Dual plate check valves are wafer, lug, or flanged ends, meeting API 6D or API 594. Dual plate check valves are retainerless designs to avoid leakage paths through the valve body.
The Double Plate Check Valve employs two spring-loaded plates hinged on a central hinge pin. The dual plate check valve is a kind of swing check valve, with features that are much shorter and less weight compared to a conventional swing check valve.
Advantages:
– Dual Plate Check Valves perform the work of almost any swing check valve. However, its smaller dimensions make it lighter and, therefore, more cost-efficient to purchase, install, and maintain.
– The Dual plate check valve is a silent check valve; because of its innovative design, it does not slam shut upon closing.
– The dual plate check valve has an important feature in that it does not rely on pressure or flow to center the plates in relation to the sealing surface in order to make the seal.
