Sub-Sea Hydraulic Actuator
Sub-Sea Hydraulic Actuator
(OP)
I am looking for manufacurers of Sub Sea Hydraulic Actuators. I received enquiries for valves c/w hydraulic actuation on occasion and never seem to have much options. Does anyone supply sub sea hydraulic actuators for needle valves?

I have only used larger hydraulic/electric actuators in subsea applications, but maybe this website will help you further.

Dantorque is a very good option:

Are the Dantorque actuators capable of modulating service if married to a hydraulic servo valve (e.g. a Moog or similar)? I can think of a couple of our butterfly valves in modulating duty on IP steam where this actuator could be a solution.

Best to talk to your local rep for more specific info.
However, as these are quarter turn actuators, I don't think they would work for Subtek.
I think the problem is that not many people supply sub-sea hydraulic actuators for linear applications, especially small needle valves. Maybe if you opened up the floor to other valve types, you might see other options for the actuator as well.

Sircrashalot, you are right. I dind't
realize subtek was looking actuation for a needle valve. Dantorque is a solution for quarter turn valves.

ScottyUK,
Dantorque actuators are designed for On-Off Service, however you could talk to your local Rep.
Shafer is also a good option on Hidraulic, Gas/Hidraulic & Subsea Applications.

I'll speak to our Emerson rep and see what he says. Thanks for the replies.
