The check valve is designed to allow fluid to flow in one direction while preventing fluid from flowing back in the opposite direction. It is equipped with a stainless steel spring, allowing for vertical and horizontal installations.
The check valve has NPT threads, which are tapered threads that provide a good seal. It has a maximum pressure of 14 bar (200 psi) and an operating temperature ranging from -10 degree C to +120 degree C (14 degree H to 248 degree H).
Suitable for water, oil, air, etc. The check valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, and urea.
The valve flap of the check valve opens under fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the outlet side, the valve flap automatically closes.
