Aluminum body; Inlet, intermediate and outlet side taps (G1/8 ISO 228); Inlet gas strainer installed in the housing upstream valves (23 mesh screen); 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 DMVZRD 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; Refer to Flow Curves for Body Selection. Conduit Adapter (240671), DIN connector (210319), and flanges must be ordered and priced separately. Code requirements vary. FM requires visual indication on 1" and larger safety valves. Two visual indicators, (VI) 266949 or one CPI 400 (CPI) 266968, and one VI meet this requirement. These also must be ordered separately.
