Frequently Asked Questions
What is a dual plate check valve?
A dual plate (double disc) check valve uses two spring-loaded semi-circular discs that open with forward flow and close against reverse flow. It is lighter and shorter than a swing check and reduces slam.
Dual plate vs swing check — which should I choose?
Choose dual plate for compact wafer installation, lower weight, and reduced water hammer. Choose swing check for large-bore low-velocity lines where pressure drop must stay minimal.
What materials are available?
Standard bodies are ASTM A216 WCB, CF8 (SS304), and CF8M (SS316). Alloy 20, Duplex, and NAB are available on project enquiry.
