Z41W/Y Stainless Steel Large Diameter Gate Valve product use
Z41W/Y Stainless Steel Large Diameter Gate Valve produced and sold by Baigang valve group has the characteristics of small fluid resistance, small impact erosion on the sealing surface, no change of medium flow direction, no disturbance and small pressure drop. It is suitable for a wide range of pressure and temperature. It is a common block valve, which is widely used for connecting or cutting off the medium in oil and steam pipelines of petroleum, chemical, thermal power plants, etc Quality. (it can not be used as throttle valve).
Z41W/Y Stainless Steel Large Diameter Gate Valve product features
1. The two sealing faces of the commonly used wedge gate valve form a wedge, and the wedge Angle varies with the valve parameters, usually 50;The gate of wedge gate valve can be made into a whole, called rigid gate;It can also be made into a gate that can produce trace deformation to improve its technology and make up for the deviation of the sealing surface Angle in the process of processing. This gate is called the elastic gate.
2, reliable sealing, excellent performance;Under normal circumstances, wedge type elastic gate structure is adopted, large diameter rolling bearing is set, easy opening and closing;Wedge gate valve has the advantages of simple shape, short structure length, good manufacturing technology and wide application range.
3. Bevel gear, electric, pneumatic and other driving devices can be selected according to users.
