Double Acting Hydraulic Gate Valve is a combination of API 6A slab-style gate valve with a double-acting hydraulic actuator.
The gate valve is fitted with a balancing lower stem to work with a double acting hydraulic actuator to provide positive, reliable control through the entire stroke of the valve. This valve will remain in position in case a failure of hydraulic power occur.
Double acting actuator that requires hydraulic power to both open and close, providing positive control during operations
Balancing stem that allows gate to stay in position unless hydraulic power is supplied to actuator to positively open or close valve
Positive metal-to-metal sealing (gate-to-seat and seat-to-body)
Two spring-loaded, pressure-energized, nonelastomeric lip seals between each seat and body, which assist in low-pressure sealing and protect against intrusion of particle contaminants into the body cavity and seal areas
Stem seal design that covers a wide range of pressures, temperatures, and fluids encountered in wellhead and manifold service
Grease injection fitting downstream of stem back seat for increased safety and fitting in bonnet that helps eliminate body penetration
Manual locking screw that maintains the gate (valve) in the closed position without any operating pressure in the actuator
Use of socket head cap screws to tie down actuator head flanges, reducing area exposed to corrosive environments
