Product Description

KOSEN Forged Bronze Check Valves is a valve that can automatically prevent fluid from flowing back. The disc of the valve is opened under the action of 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 disc automatically closes under the action of fluid pressure difference, gravity and other factors to prevent fluid backflow.


1.It adopts pressure self-sealing structure, while ball valve needs external force.

2. Check disc limit device can prevent valve disc from opening too high to close.

3. Precise installation of solid pin shaft of check valve and high strength guarantee the service performance and service life of valve.

4. The joystick has sufficient strength and has sufficient freedom to close the disc.

5. Check disc has sufficient strength and stiffness. The sealing face of disc can be welded with metal material or inlaid with non-metal material according to user requirements.
