JNB & JNO-H

Style JNB balanced bellows valve

Bellows

Style JNO-H open bonnet valve

JNB Balanced Bellows type

A high capacity Safety-Relief Valve, but developed especiallyfor services where the valve must operate under conditionsof built-up or superimposed back pressure due to beingconnected to a closed blowdown system, and for thoseservices where severe corrosion or fouling of working partscan be anticipated. The bellows subassembly is the onlyconstruction difference between style JNB and JNO valvesand conversions from one style to the other are simple.

JNO-H Open Bonnet type

Style JNO-H with open bonnet and Type C regular liftinglever is available as an option for ASME Section VIIIsteam applications. Only the bonnet need be changed toconvert a Style JNO Type C to Style JNO-H.With the open bonnet feature, carbon steel spring materialcan be used to +343˚C (+650F).

JLT & O-Ring

JLT Liquid Trim Style JLT standard for liquid service

Full lift and rated capacity at 10% overpressure with stable operation from a pressure relief valve specificallydesigned for liquid service.

High Coefficient of Discharge

The JLT Liquid trim construction has a high coefficient of dis-charge. Generally a smaller JLT orifice size may be selectedthan that of a conventional pressure relief valve sized forthe same application. Smaller orifice sizes mean reducedvalve and related piping costs.

High Capacity at 10% Overpressure

Published valve capacities are based on capacity certificationtests performed at 10% overpressure. This eliminates theneed to use the traditional overpressure derating factorbased on 25% overpressure is based on the ASME Boiler andPressure Vessel Code that permits pressure in a vessel to rise10% above the maximum allowable working pressure(MAWP) of the vessel during an overpressure excursion.

As system pressure approaches the valve set pressure, the differentialforce tending to hold the seats in contact is diminished. Consequently,to obtain an acceptable degree of tightness capability, the valvemust be designed and built with a high level of quality.

MOTOYAMA pressure relief valves are carefully engineered andmanufactures ti provide those features essential for good valveperformance and continuous long term protection. The inherenthigh degree of seat tightness found in MOTOYAMA pressurerelief valves is possible due to the following design features.

1. Positive alignment of the seats through generous guiding andball joints.

2. Minimum distortion as a result of full nozzle construction andthermally balanced disc design.

3. Excellent flatness and surface finish of the seating surfaces byprecision machining and custom lapping.

Cleanliness of the system and proper installation of the valve arealso essential for good seat tightness.

DefinitionAmbiguous terms such as "bubble tight", "drop tight", "zeroleakage" and "commercial tightness" have been used in the past.Since these terms were used without uniform definition, theylacked true practical meaning.

Now with the adoption of a standard that defines the terminologyused to describe pressure relief devices (ASME Performance TestCode PTC-25.3), and the adoption of a standard describing a methodof determining seat tightness of relief valves (API Standard 527),there should exist a degree of uniformity throughout the industry.

"Commercial" Seat Tightness Standard(API Standard 527)The following API Standard of "commercial" tightness has beenadopted by industry and users in order to clarify testing methodsand tightness standards for the sake of uniformity. It applies topressure relief valves.

The API Standard is as follows:

Scope:This standard describes a method of determining seat tightness ofpressure relief valves as covered in API Standard 527 Seat Tightnessof Pressure Relief Valves. The maximum acceptable leakage rates aredefined for commercial pressure relief valves with, metal-to-metaland soft neats for set pressures up to 6000 psig (414 barg). Ifgreater tightness is required it can be supplied but must be specifiedon the purchase order or inquiry. See page 6 for O-Ring soft seatpressure-temperature limits.

Test ApparatusA typical test arrangement for determining seat tightness for pressurerelief valves is shown in Fig.1. Leakage measurement shall be madewith use of a 5/16 in. (7.93 mm) OD tubing with 0.035 in. (.88 mm)wall. The tube end shall be cut square and smooth. It shall be parallelto and 1/2 in. (12.7 mm) below the surface of the water A clamp typeseat leak apparatus is available from Crosby. Contact the factory.

ProcedureWith the valve mounted vertically, as shown in Fig. 1, the leakagerate in bubbles per minute shall be determined with pressure at thevalve inlet held at 90 percent of the cold differential test pressure,except for valves set at 50 psig (3.44 barg) or below, in which case thepressure shall be held at 5 psig (.34 barg) below the cold differentialtest pressure. The test pressure shall be applied for a minimum of 1minute for valves of inlet sizes through 2 in. (50.8 mm); 2 minutesfor sizes 2-1/2, 3 and 4 in. (63.5, 76.2 and 101.6 mm); 5 minutes forsizes 6 in. and 8 in. (152.4 and 203.2 mm). Air at approximatelyatmospheric temperature shall be used as the pressure midium.

Tightness StandardThe leakage rate in bubbles per minute shall not exceed the val-ues indicated in Table 1 below. For soft seated valves there shallbe no leakage for one minute (zero bubbles for one minute)

Table 1

Maximum Seat Leakage RateMetal Seated Pressure Relief Valves

MOTOYAMA Seat Tightness Standard-Water Service Valves(Style JLT)MOTOYAMA pressure relief valves are checked for seat tightnessby a quantitative seat leakage test. All of the test fluid passingthrough an assembled valve is collected and measured under thefollowing test conditions:

1. The inlet pressure is adjusted to a test pressure which is 90% of the"Cold Differential Test Pressure". Valves set below 50 psig (3.44barg) are tested at 5 psig (.34 barg) below the cold differentialtest pressure.

2. The seat leak pressure is maintained for a period of not lessthan ten minutes.

Allowable Leak RateThe maximum allowable leakage rate should not exceed 10 cubiccentimeters per hour per inch of diameter of nominal valve inletsize. For nominal valve sizes of 1 inch(25.4 mm) or less the leakagerate shall not exceed 10 cubic centimeters per hour. For soft seat-ed valves there shall be no leakage for one minute.

Valve installation

StorageRelief valves are often on hand at the job site months before theyare actually installed. Unless they are properly stored and protectedtheir performance may be affected injuriously. Roughness in handlingmay damage flanges or cause misalignment of the valve parts. It isbest to leave valves in shipment cases, store them in a dry placeand give them a protective covering until they are to be used.

InstallationInlet Piping–The valve should be mounted vertically in an uprightposition either directly on a nozzle from the pressure vessel or ona short connection fitting that provides direct and unobstructedflow between the vessel and the valve Installing a pressure reliefvalve in other than this recommended position might adverselyaffect its operations. Where rounded or beveled approaches cannotbe provided ahead of the valve it is recommended that one sizelarge riser or fitting be used. A valve should never be installed ona fitting having a smaller inside diameter than the inlet connectionof the valve. Compliance with the above recommendations willassure clean positive valve operation.Many valves are damaged when first placed in service because offailure to clean the connections properly when installed. Both thevalve inlet and the vessel and/or line on which the valve is mountedmust be thoroughly cleaned of all foreign material. The inlet con-nection bolts or studs should be drawn down evenly to avoidstraining the valve body with possible distortion of the nozzleflange or base. The design and analysis of the inlet piping for apressure relief station must include all of the valve operatingforces (reaction forces) as well as the installation loads and forces.

Outlet Piping–Discharge piping should be simple and direct.Where possible a short vertical pipe discharging into the atmosphereis the most desirable type of outlet piping, and affords little trou-ble. (See illustration.) However, if this is impractical and the dis-charge must be piped to some definite place, the precautions list-ed below should be carefully considered.

All Valves:1. MOTOYAMA valves are designed with reinforced inlet necks to

minimize effects of discharge piping loads. However, regardlessof this reinforcement, discharge piping should be designed forminimum load on the valve under all conditions of valve operation.

2. Expansion joints or large radius bends of proper design andcold spring should be provided to prevent excessive strain onthe valve body under normal operating conditions. An excessiveexpansion load is a continuous source of trouble in improperlydesigned installations. (See illustration below.)

3. The piping should be anchored to prevent any swaying or vibrationwhile the valve is discharging.

4. Where possible, open drains should be provided to prevent anyaccumulation of corrosive media in the valve body.

Conventional Valves5. When two or more valves are installed to discharge into a common

header the discharge pressure due to the opening of one (ormore) valve(s) may affect the opening pressure of the remain-ing valves in the system.

5a Closed Top Valves With Bonnets NOT VENTEDThe discharge line pressure of these valves will increase theopening pressure by the amount (p.s.i.) of the discharge pressure.

5b Closed Top Valves With Bonnets VENTEDThe set pressure of the remaining valves in the system will bereduced by the amount(p.s.i.) of the discharge pressure.

Where either of the above conditions are unacceptable the use ofStyle JNB Balanced Bellows valves as described below is recommended.

Note: Conventional Valves with vented bonnets are not suitablefor continuous back pressure.

Bellows Valves5c The Style JNB Balanced Bellows Safety-Relief valve is particularly

adapted to installations where two or more relief valves mustbe vented into a closed exhaust system resulting in variableback pressures which would affect the performance of a con-ventional type relief valve. The metal bellows used in Style JNBis so designed that the effective area of the bellows is equivalentto that of the valve seat. Because of this balanced area design,back pressure surges, whether constant or variable, do notadversely affect the performance of the valve. These valves areregularly furnished with atmospheric vents from the bonnet.

Flanges and flange facing

Dimensions of flanges conform to current ASME (ANSI)standards. On full nozzle valve inlets, however thethicknesses are greater than the minimum required byASME (ANSI) standards. Dimension X shown oppositeshould be used to determine bolt length. Dimension Xremains the same for raised face or ring joint flanges andis found on pages 10 through 36.

All flange facings are finished with spiral serration.Concentric serration finish are optional. Flange facingson valves for marine or Navy use must follow govern-ment specifications. Drilling of inlet and outlet flangeholes straddle the valve center line. Inlet and outletflanges are spot faced on back for stud nuts. Center-to-face dimensions are Subject to tolerance of±1/16"(1.5 mm) for valves through 4" inlet size and±1/8"(3.2 mm) for valves with inlet size larger than 4".

In addition to standard raised face or ring joint flanges,tongue and groove or other facings are optionallyavailable.
