Reotemp M30HNNS Three Valve Stainless Manifold

The Reotemp M30HNNS 3-Valve Manifold is a stainless-steel instrument manifold designed to mount to differential pressure gauges or transmitters, delivering two isolation valves plus an equalizing valve in a compact, easy-to-service package. The model code M30HNNS denotes a 3‑valve layout (M30), hard-seat configuration (H), 1/2" female connections on both ends (NN), and a stainless-steel body (S); this exact configuration is shown in Reotemp’s ordering options, with M30HNNS-M2NC cited as an example. Built with a 316 stainless steel body, it features a 0.187" orifice and a flow coefficient (CV) of 0.44 for hard-seat operation and 0.76 for soft-seat operation, with a hard-seat rating up to 10,000 psi at 200°F and a soft-seat rating up to 6,000 psi at 200°F. The manifold can be configured for block, single-flange, or double-flange connections to suit remote or direct installation. In application, it serves as a ready-to-install differential-pressure accessory that simplifies measurement tasks by allowing isolated servicing of the gauge or transmitter and controlled equalization between legs. Typical uses include process instrumentation where stable, adjustable pressure sampling is required, such as in DP gauge installations and pressure transmitter hookups in industrial environments.
