API 6A hydraulic gate valve 3 1/8 5000psi

API 6A hydraulic gate valve 3 1/8 5000psi

Description:

Full bore design eliminates efficiently pressure drop and vortex, eliminates washing by solids in fluid.

• Special seal type lower switch torque.

• Mental-to-mental seal is used between bonnet and body, gate and seat rising.

• Mental-to-mental seal between gate and seat, and the surface is weld overly with hard alloy, which has feature of corrosion resistance and washing resistance.

• Retainer plate fix seat ring insuring good stability.

• The stem designed with back seal, can replace stem sealing under pressure.

• One side of bonnet is designed with sealant injection in order to supply sealant and improve seal and lubrication performance of gate and seat.

• Can complete with different pneumatic (hydraulic) actuator upon user’s requirements.
