The pneumatic control valve is composed of an actuator and an adjustment mechanism The actuator is the thrust component of the adjustment valve. The valve body is the regulating component of the pneumatic regulating valve It directly contacts the regulating medium to regulate the flow, pressure, temperature and other process parameters of the fluid. Without additional explosion-proof measures.
Application: petroleum, chemical, electric power, metallurgy, etc.
We offer self-operated pressure, differential pressure, and flow-regulating valves three series self actuating pressure control valve. Pressure regulator type and pressure relief type are available. The self-operated pressure regulating valve does not need additional energy and can work in a situation without electricity and gas, which is convenient and energy-saving. The pressure balance mechanism is adopted to make the regulating valve sensitive and accurate to control.
The valve disc and valve seat sealing surface of the pneumatic control globe valve are made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing. The valve stem has been tempered and surface nitrided, and has good wear resistance, high temperature resistance, and corrosion resistance. Corrosion-resistant, scratch-resistant, and long service life.
The medium flow direction of the stop valve changes from the top of the valve disc to the valve cavity. Under medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be reduced accordingly.
Pneumatic globe valve is a forced sealing valve. The sealing surfaces of the valve disc and valve seat are made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, which has the characteristics of good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life. When the pneumatic valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage.
The valve is a low-platform rising pole industrial straight stroke pneumatic gate valve (double-layer cylinder with buffer mechanism) and manual with protection mechanism (manual and self-locking air manual switching device). Adopting a double-layer cylinder structure, fundamentally solves the common problem in single-cylinder pneumatic gate valves that the valve body wedge is stuck and cannot be opened. It is also equipped with a buffer mechanism, reducing wear on the sealing surfaces and preventing the gate from seizing.
