Ball Type Check Valve Introduction

Ball check valve is a kind of check valve with multi-ball, multi-runner and multi-cone inverted fluid structure, which is mainly composed of front and rear valve body, rubber ball, cone body and so on.

Its working principle is: the rubber ball in the ball cover for a short trip rolling to realize the opening and closing of the valve. When the pump starts, the water under the action of pressure to open the rubber ball, so that the rubber ball rolled to the right, by the back of the valve body in the cone body to fix its position, the check valve is open; pump stops, due to the piping system in the backwater pressure, forcing the rubber ball rolled to the left side of the front valve body, to achieve the closure of the check valve. The rubber ball is made of hollow steel ball, and the rubber with good elasticity is used to ensure the sealing and reduce the damage to the pipeline system in the process of closing the valve. Cone with holes in the valve when the valve is opened on the steel ball to play a fixed role and eliminate the rubber ball and cone contact area of the pressure, so that the contact for the surface contact, reducing the rubber ball in the valve body of the hydraulic loss caused by trembling.

This valve is made with strong and durable materials, ensuring long-lasting performance. Its ball design allows for a tight seal and prevents any backflow, keeping your system running smoothly. Trust the expertise and quality of this valve to secure your system's functionality.
