Check valves for servo drive JCM

The JCM check dampers are servo-ready (e.g. BELIMO) and are designed for TH, CRV, CRH and HCT roof fans. JCM dampers are made of double-sided galvanized sheet metal for optimum durability with respect to the ductwork and roof fans used. Check dampers are an important part of the HVAC ductwork to prevent unwanted air backflow.
