API 6A Hydraulic gate valve to be wellhead valves, API 6A Hydraulic gate valve is applicable for oil and gas wellhead. API 6A Hydraulic gate valve is designed, manufactured and tested as per API Spec. 6A. The API 6A Hydraulic gate valve open and close is controlled by hydraulic piston, which can be safer and quicker, valve stem packing and seat are elastic energy storage sealing structure, which has good seal performance, and valve with balance tail rod, lower valve torque and indication function, moreover, double acting actuator requires hydraulic power to open and close, which can provide positive control during working. API 6A Hydraulic gate valve is often used in oil and gas industry. Note: Hydraulic actuator: 3000psi working pressure and 1/2” NPT connection
 

API 6A Hydraulic gate valve design specification:
API 6A Hydraulic gate valve is in accordance with API 6A 21th latest Edition, and use the right materials for H2S service according to NACE MR0175 standard.
Product Specification Level: PSL1 ~4　　　 Material Class: AA~FF　　 Performance Requirement: PR1-PR2　Temperature Class: LU
 

API 6A Hydraulic gate valve features:
◆ Balancing stem that allows gate to stay in position unless hydraulic power is supplied to actuator to positively open or close valve
◆ Gate to seat, seat to body, bonnet seal and stem backseat are metal to metal sealing
◆ Linear double acting actuators guarantee opening valves rapidly in 30 seconds .
