Due to the pressure of the inlet medium in the pipeline, and to overcome the spring resistance make the valve opened or closed. When the inlet pressure of medium below the outlet, the spring into the valve core seat and make the valve closed, stop medium counter-current, start-stop function back. Stainless steel vertical check valve is widely used in chemical engineering, liquefied petroleum gas, liquid etc.
Stainless steel vertical check valve is rely on the medium itself and automatically open and close to prevent medium refluent valve and also is called cut-off valve, one-way valve, reflux valve and counterbalance valve. Check valve is an automatic valve, its main function is to prevent medium backflow, prevent pump and drive motor reversion and medium tapping. Check valve is also used to give the pressure could rise to more than the system pressure of the secondary system supply piping.
This type of valve's role is only allowed to medium flows in one direction. This valve is normally automatic work, in a direction of flow of fluid pressure and valve opening; In the opposite direction of fluid flow, the fluid pressure since the overlap of the disc and the disc on the seat, thereby cutting off flow.
The specifications of Stainless steel vertical check valve are:
1. Pressure: Mpa1.6 / 2.5 / 4.0, 150Lb-900Lb
2. Valve body materials: WCB(C) /CF8(P) /CF 8M (R) /WC6 /WC9; 20#, A105
3. Working temperature: ≤ 425 / ≤ 100 /≤ 100/ ≤ 550 /≤ 550
4. Application medium: Water, steam, oil, nitrose, acetic acid etc.
