BH Series Dual plate wafer check valve

Product Detail

Description:

BH Series Dual plate wafer check valve is the cost-effective backflow protection for piping systems,as it is the only fully elastomer-lined insert check valve.The valve body is completely isolated from line media which can extend the service life of this series in most appications and makes it an especially economical alternative in application which would othervise require check valve made of expensive alloys..

Characteristic:

-Small in size, light in weight, compact in sturcture, easy in maintenance.-Two torsion springs are added to each of the pair valve plates, which close the plates quickly and automatically. -The Quick cloth action preventsthe medium from flowing back. -Short face to face and good rigidity. -Easy installation, it can be installed on both horizontal and vertival direction pipelines. -This valve is tighly sealed, without leakage under the water pressure test. -Safe and reliable in operation, High interference-resistance.
