Need assistance specifying Emergency Shutdown Valve (ESD)

(OP)
Currently the client has provided the following information, and he has asked me to help him with the specification -

Application: liquid condensate truck fill skid
No air available, must use electric actuator (480V available)
3", 150# RF Flanges
Ball valve
CS body, SST trim
Must handle 100 gpm @ 50psi, 125F
Area Classification Class 1 Div 2

Any help with type/line of valve and actuator assembly would be greatly appreciated.

RE: Need assistance specifying Emergency Shutdown Valve (ESD)

there are so many ESD ball valves can be used for your application, thost picked a right one for you. the only issue is that if it is for salty water or other corrosive liquid, trim material has to be carefully selected.

RE: Need assistance specifying Emergency Shutdown Valve (ESD)

by the way, oil hand pump is not very good for cold winter like in Canada, a mechanical hand wheel and clutch would be better.

RE: Need assistance specifying Emergency Shutdown Valve (ESD)



1. You have to specify, or let the enduser specify needed closing time.
2. Use a reputable ball valve brand / manufacturor.
3. Order the ballvalve and actuator (specified or suggested/accepted type) as a complety mounted unit supplied and tested from one (responsible) source.
4. Performance test described, agreed from supplier before acceptance.

Other types of electrical actuators: BIFFI with spring return. Check suppliers for offshore arctic North-Sea for quotes or recommondations/references (UK or Norwegian suppliers)
