ZJHK-320 pneumatic film multi-stage throttle high pressure regulating valve is designed according to the principle of step-down of multiple valves in series. Several window holes (or multi-stage valve seat holes) with a certain shape are opened on the sleeve, and high pressure liquid is wound around the valve core and sleeve window holes (or multi-stage valve seat slots), which expand through multiple throttling, and the fluid enters from the sleeve. From mouth to exit, the pressure difference is gradually reduced to achieve the purpose of air defense. The product can be widely used in high pressure differential occasions such as petroleum, chemical industry and power station.
