 Introduction: 

• 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
