Structural advantages and characteristics of cast steel stop valves
Steel stop valves are designed and manufactured in accordance with national standards, with reasonable structure, reliable sealing, excellent performance and beautiful appearance.
The sealing surface of the flap valve seat is made of iron-based alloy surfacing or Stellite cobalt gold hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life.
The valve stem diameter is modulated and the surface is nitrided, which has good corrosion resistance and scratch resistance.
Using various piping flange standards and flange sealing surfaces to meet various engineering needs and user requirements.
The body materials are complete in variety, and the fillers and gaskets can be reasonably selected according to actual working conditions and user requirements, and can be applied to various pressure temperatures and medium working conditions.
The seal is made of threaded sealing seat or body surfacing of austenitic stainless steel. The sealing is reliable and the packing can be replaced without stopping the machine. It is convenient and fast and does not affect the operation of the system.

Operation Principle and Structural Description of Cast Steel Globe Valve
When the handwheel turns clockwise, the valve stem moves downward, and the valve disc drops to make the sealing surface close and cut off the passage. When the valve is turned, it opens, and the seal works when the valve stem is raised to the highest point.
This valve adds an upper seal, which acts as a two-layer seal together with the packing when the valve is open, and has a certain protective effect on the packing
This valve uses nylon products as the sealing surface, and the packing is soft molding packing. , the upper seal is also made of soft material, with good sealing performance
