Dual Modular Safety Shutoff Valves w/ Two-stage operation and Proof of Closure DMV-ZRD(LE)/612 Series
The Two-Stage Dual Modular Valve DMV-ZR/612 series combines two safety shutoff valves in one compact housing. Valve 2 incorporates two stages which can be set at two different firing rates. Both firing rates are field adjustable and can modulate from high to low during burner operation. Valve 1 (V1) of the DMV-ZRD and DMV-ZRDLE series is fast opening and fast closing. Valve 2 (V2) of the DMV-ZRD is fast opening while V2 of the DMV-ZRDLE is slow-opening for smoother light-off. Max. flow adjustment on V2 provides variable main flow on both models.
Application: The DMV-ZR is recommended for industrial and commercial heating applications, where two automatic shutoff valves, proof of closure and modulating between two firing rates during burner operation are required. The DMV-ZR Dual Modular Valve two stage is suitable for dry natural gas, propane, butane, air and inert gases.
A “dry” gas has a dew point lower than +15° F and its relative humidity is less than 60%.
