J961 electric high-pressure valve 



 Design, characteristics and uses: 
 1 body and bonnet connection form: PN10-64 using bolted bonnet; PN64-320 using a self-pressure seal bonnet. 
 2 Stem nut: Under normal circumstances, stem nut material is ASTM A439 D2, while the use of copper alloy according to user requirements and other material for large-diameter valve, mounted bearings, can effectively reduce the valve opening torque to the the valve can easily switch. 
 3 stem design: the use of the whole forging process is made in accordance with standards to determine the minimum diameter. 
 4 valve cover gasket forms: PN10-64 cut-off valve with stainless steel graphite spiral wound gasket; PN100 stainless steel valve can also be metallic graphite spiral wound gasket ring gasket; PN160 metal ring gasket can be cut-off valve, PN320 valve pressure using a self-sealing metal ring. 
 5 valve structural features: Bolted bonnet, rod bracket and lift out the metal stem cover. 
 6 seat on the seal design: Our company provides all the valves are closed down design, typically, carbon steel valve seat design using separate inverted sealing structure, the inverted stainless steel valve sealing surface is very reliable. Although there are inverted according to the standard API600 seal, but not as a replacement in case of filling with a pressure basis.
