Product Overview
Dual Plate Check Valves are compact, high-performance non-return valves designed to prevent reverse flow with low pressure drop and fast closing action. The dual spring-loaded plates ensure quick response, minimizing water hammer and enhancing system protection.
MNC Dual Plate Check Valves are manufactured in Wafer, Lug, and Double Flanged constructions for Class 150 / 300 / 600 pressure ratings, suitable for water, wastewater, HVAC, oil & gas, chemical, power, and general process piping systems.
