Model C Hydraulic Actuator

The Model C Hydraulic Actuator takes a unique method in that the piston assembly is moved to the bottom of the actuator, allowing the power spring to be submerged in clean hydraulic oil, preventing corrosion even under extreme working circumstances. This actuator is ideal for remote locations where routine maintenance is a challenge. When the control pressure is lost, the C has a powerful power spring that assures complete gate closing. This actuator also has an unique Quick Disconnect function that allows the bonnet to be disconnected from the actuator, allowing the actuator to be serviced while the bonnet safely retains pressure inside the gate valve.

The Model C actuator is capable of controlling valves with diameters ranging from 1-13/16” to 4-1/16” and operating pressures up to 10,000 psi (689 bar). 6-3/8” gate valves with operating pressures up to 5000 psi are likewise controlled by the actuator (345 bar). Actuators with a 3” or 4” piston are offered to optimize control pressures to satisfy application requirements. Hydraulic actuators from the Model C series include: Overpressurization of the actuator is prevented by an external safety release mechanism. Long-term operation and dependable closing are provided by a power spring submerged in pure hydraulic oil. The Quick-Disconnect function allows the actuator to be removed without depressurizing the valve, substantially reducing downtime and lost revenue.The actuator shaft is visible, giving a visual indication of the position of the gate valve.
