Double Acting Hydraulic Gate Valve

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.

Features

Double Acting Hydraulic Gate Valve
  • 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)
  • Bidirectional flow
  • 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
