Gate valve

SCOTON gate valve with single gate and full bore. Suitable for double flange, thread end and special connection. Pressure range: 2000psi to 20000 psi. DN size: 1 13/16" to 9",  Can used with our SCOTON actuator.

Main features of  Wellhead Gate Valves are as follow

• Double-way downstream Sealing structure, prolong service life.
• Fixed metal seal, (between gate and seat, seat and body)
• Simple, reliable gate and seat design can reduce site service and keep the minimum spare parts storage.
• The sealing ring between seat and body can help to seal in low pressure environment, it also can prevent granular pollutant goes into valve bore and sealing area.
• Stem seal design covers all pressure range and temperature range, and all fluid environment in well head and manifold.
• Metal seal between bonnet and body.
• Stem back seal structure allows valve replace stem seal under pressure activate.
• To ensure safety, injection device can put behind of stem back seal, it can put on bonnet and eliminate body leak.
• Low open-close torque, easily to open and close.
