Zhejiang Yongjia County Lin Wanle county magistrate visit ST valve
Flow direction of medium in globe valve includes "low in and high out" and "high in and low out". The medium is allowed to flow in only one direction. The valve shall be installed in right direction.Globe valve has structure of straight-through type, direct flow type and right angle type.When globe valve is open, and the opening height of valve clack is up to 25% ~ 30% of nominal diameter of the globe valve,the flow reaches the maximum which show that the valve reaches the fully open position.
Structural features:
1. Wide application range
2. The cavity adopts self-sealing structure, the higher the pressure, the better the sealing performance
3, the surface welding company is too rigid carbide, wear resistance, corrosion resistance, good friction resistance, long service life
3, the valve stem surface after more than compact wear (nitriding) treatment, small opening and closing friction, to ensure that the product no leakage
4. There are three bonnet designs: bolted bonnet, welded bonnet and pressure self-tightening bonnet
(1) : Bolted bonnet, valve designed in this form, having a body and bonnet connected by bolts and nuts, sealed with a wound gasket (made of 316 flexible graphite clamps).Customers with special requirements can also use metal ring connection.
(2) : Welded bonnet, designed in this form of valve with a body threaded to the bonnet and fully welded seal.Customers with special requirements can also use full welding connection.
(3) : Pressure self-tightening valve cover, according to the design of the valve in this form, the body and the valve cover with thread connection, internal pressure self-sealing ring seal.
5. Manual and pneumatic operation modes are available
6. Flange and welding size can be reasonably selected according to actual working conditions to meet various needs
