Materials: stainless steel products

The plunger globe valves are introduced in detail
A product use
Globe valve piston ring due to adopting new nonmetal materials, high temperature, high voltage withstand long without loss of elasticity of the performance and plunger and sealing between large contact area, moreover, sealing ring is mixed material performance is good, therefore, sealing is reliable and durable. Mainly used in metallurgy, chemical, electric power, oil refining, chemical fertilizer, light industry, food industry etc
A product features
1 and in valves with a seal, through the adjustment of flange bolts pre-tightening force, sealing the lateral force produced by compression and body surface area and the column in the round hole sealing, so as to ensure the valve sealing, eliminate the external leakage
2, due to strong resistance, sealing ring with exciting new type sealing material of non-toxic high, so the sealing is reliable and durable, so as to improve the service life of the valve
3 and the valve piston valve with no leakage advantages and globe valves open, and become a kind of novel structure, widely used in varieties
