Manual gate valve

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.
