Check Valve – KRD-DPC

Dual plate check valve with built-in retainer (no hole passing through the body) for a wide range of applications.

The dual plate check valve is one of the most compact check valves.
This valve design is the result of attempts to provide an alternative solution to the problems associated with swing check valves.
Compared to a conventional swing check valve, it is much stronger, lighter and smaller in size.
The two plates of the dual plate check valve are hinged vertically in the center, eliminating the effect of gravity in horizontal installations.
When fluid enters the valve, pressure opens the flaps, stretching the spring.
When the valve closes, the flow cushions the plates and seat, so the risk of slamming is negligible.
