Ball Check Valve

The rubber ball adopts hollow steel ball with elastic rubber to ensure sealing and reduce the damage to the pipeline system in the process of valve closing. When the valve is opened, the conical body with holes can fix the steel ball and eliminate the pressure on the contact surface between the rubber ball and the conical body, so that the contact is surface contact, and reduce the hydraulic loss caused by the trembling of the rubber ball in the valve.

In large piping system with three port or four port ball check valves can replace a large valve plate structure, reduce weight of valve plate, the passage is free-standing porous structure, sphere put in every hole, in the process of the liquid into the body and out of the way its, mutual interference, reduce impact and vibration in the process of valve, reduce the noise, and eliminate any running fault. Multi-channel spherical check valve has no joint parts (shaft and shaft sleeve exist, no relative mechanical friction movement, compared with swing check valve, no wearing parts exist, with a long service life, and no maintenance work.
