Ball check valve

 Ball check valve is designed to prevent medium backflow in piping systems. Distinguishing itself from traditional swing check valves and lift check valves, it adopts a free-floating, rubber-coated spherical sealing structure without complex hinges, swing arms, or movablel disc shafts. This simplified internal design offers good stability and anti-clogging performance, and an instant response for water supply, wastewater, and industrial pumping systems.

• Low Flow Resistance: The straight-through, full-bore design minimizes head loss and pipeline pressure drop, effectively reducing pump

operating energy consumption and improving overall system efficiency.


• Fast Closing & Water Hammer Reduction: The floating ball resets instantly under reverse medium pressure. This rapid shut-off action

greatly suppresses water hammer impact, protecting pumps, pipes, and auxiliary equipment from pressure damage during frequent

start-stop operations.


• Anti-Clogging & Low Maintenance: Free of hinges, pins, or bearings, the spherical rolling structure prevents fine sediment, fiber, and

impurities from getting stuck. This self-cleaning action ensures long-term stable operation with minimal maintenance.


• Zero-Leakage Tight Sealing: Featuring an EPDM/NBR fully encapsulated ball and a precision-machined seat, the soft-sealing

configuration achieves bubble-tight, zero-leakage shut-off, guaranteeing reliable one-way flow control.


• Flexible Installation: Supports both horizontal and vertical pipeline installations (with upward flow), offering versatile layout solutions

for complex engineering designs and limited installation space.
