Product details
Introduction to H77X/W type clamp rotary check valve
Adopting short structural dimensions and dual valve disc design. Compared to traditional swing check valves, this series of valves has the advantages of no external leakage, can be installed in any position, good sealing performance, low linear vibration, low pressure drop, and zero seat ring wear. BEUB can provide products with connection sizes that comply with American and national standards.
Characteristics of H77X/W type clamp rotary check valve
It has the characteristics of short structural length, small volume and light weight, fast closing of valve disc, low water hammer pressure, smooth flow channel, low fluid resistance, and can be used in both horizontal and vertical pipelines. It is easy to install, sensitive to action, good sealing performance, short valve disc stroke, low impact force when closing the valve, simple and compact design, beautiful appearance, long service life, high reliability, prevention of medium backflow, automatic control, etc.
