Metaval Dual Plate Check Valves are compact, lightweight, and efficient non-return valves designed for high-performance applications. Featuring a spring-assisted dual disc mechanism, these valves close quickly to prevent water hammer and reverse flow, making them ideal for both vertical and horizontal installations in space-constrained piping systems.
