The SSV is the device that blocks or allows the flow thru the production line. It is therefore an essential part of the Surface Safety System. It´s components are a Model “S” gate valve plus an actuator. The combination of the Model “S” gate valve with an inverted port gate (the opening port is in the upper section of the gate) and our actuator, results in the SSV to be normally closed.
The model S valve can be supplied with pneumatic or hydraulic actuators.
The pneumatic or hydraulic operated valves, meet a wide range of applications in oil and gas services up to 10,000 PSI, they can be supplied with pilots, filters and all the necessary elements that compose and integrated surface safety system.
In case of hydraulic operated valves, they can be supplied as self-contained packages. These units do not require external power source.
Actuator´s main features are to have Internal sleeve protected with Non Electrolytic Nickel Coating, non-elastomeric stem packing, Metal to Metal backseat between stem & bonnet, adjustable built-in stroke limit and to be easy inspection and repairing.
The pneumatic actuators are simple effect piston actuators designed to operate any gate valve. These actuators can be powered by wellhead gas, treated gas, air or nitrogen.
