Description

The Two-Stage Dual Modular Valve (DMV-ZR) combines two safety shutoff valves in one compact housing, which can be wired independently or in parallel.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) is a two stage valve. 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.

Internal profiles and compact design optimize flow and provide a low pressure drop. Three body styles reduce inventory. Directly mounting the following accessories creates a compact valve train without additional piping: pressure regulator, high and low gas pressure switches, valve proving system, and vent line adapter.

Application

The DMV-ZR is recommended for industrial and commercial heating applications, where two automatic shutoff valves 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 %.
