The ball check valves have excellent waterproof hammer function, which is mainly composed of a spherical device and a valve body, with a simple structure. The spherical device consists of a ball cover and a rubber ball. The rubber ball is processed from steel plate into a core and lined with a rubber layer to maintain a certain degree of elasticity and sufficient strength.
Designed with a full bore design, the head loss is about 50% smaller than that of the rotary opening type, resulting in significant energy savings.
The shutdown speed is fast, effectively suppressing water hammer and protecting pipelines and equipment.
Adopts a soft sealing design (EPDM), ensuring excellent sealing performance and silent shutdown operation.
