Ball check valve, rubber for the disc, under the action of the medium, can be in the valve body of the integrated slide up and down, so as to open or close the valve, sealing performance is good, noise-cancelling closed, do not produce permanent hammer.The valve body adopts full flow channel, with large flow, small resistance and 50% lower head loss than swing type. It can be installed horizontally or vertically. It can be used in cold water, hot water, industrial and domestic sewage networks.Suitable for submersible sewage pump, medium temperature is 0~80℃.
1. The valve body adopts full channel and streamlined design, with small fluid resistance and large flow rate.
2. The joint of body, cover and piston rod is sealed by sealing gasket and sealing ring with no leakage.
3. Valve body, piston cylinder, piston double guide, smooth and reliable movement.
4. All stainless steel piston cylinder, monolithic cast piston, NBR sealing ring.
The perfect combination greatly extends the service life.
5. Removable valve seat with advanced technology, with clever structure, novel conception and convenient maintenance and replacement.
6. The piston cylinder with diversion holes can increase the resistance properly to make the piston motion more stable.
