Voice of Customers 用户心声

“In comparing the

different actuator

manufacturers … it was

demonstrated, that for a

total of 133 quarter turn

ESD valves varying in size

between 3” and 20”, an

initial weight difference

of 13 tons was separating

manufacturer “A” from

Bettis.”

“我们有133台角行程紧急关断阀，尺寸从3寸到20寸不等。通过对不同执行机构厂商的比较，我们发现安装Bettis的阀门总重量要比安装其它品牌执行机构的阀门总重量轻13吨。”

“. . . project, where process pressures

where higher and size varied between

3” and 24”, a weight difference of 17

tons was separating manufacturer “A”

from Bettis.

我们的项目是高压环境下的，阀门尺寸从3寸到24寸不等，安装Bettis的阀门要

比安装其它执行机构总重量轻17吨。

“. . . an average weight

reduction of 22% was noticed

with brand “Bettis” against all

others, with the spread

increasing as the torque

requirement increases.

An average reduction of 20% of

the dimensional envelop was

achieved, effectively offering a

smaller foot print

A volumetric displacement

reduction of 24% was noticed

as the actuators used where

often of smaller size to achieve

same torque output.”

“通常小尺寸意味着小扭矩，体积减少24%的同时，意味着扭矩输出的减少。而

Bettis执行机构在扭矩输出增加的情况下，仍然比其他执行机构重量轻22%，体积

小20%。”

“ . . the mechanical efficiency of the

different units was varying between 62%

and 90%, with design “B”,”C”& “D” in the

60% range, while Bettis design did

demonstrate greater mechanical

efficiency and less energy loss showing

a mechanical efficiency in excess of

90%.” “不同设备的机械效率在62%-90%之间，安装“B”,“C”,“D”三个品牌的执行机构后，设备的机械效率在60%左右，而安装Bettis后，设备的机械效率超过了

90%。”
