Hex Valve's HM54 Double Flanged Three Valve Manifold
The HM54 Series is a double flanged instrument manifold that is used to perform the block, equalizing and vent requirements of differential pressure transmitters.
For compact, close-coupled installations, the manifold bolts directly to the instrument and can be mated directly to the orifice flange using futbol flanges and short nipples. For remote installation, tube adaptors are used with the futbols.
The non-rotating tip (NRT) stem provides tight, repeatable shutoff without the galling or cross-scoring that occurs on ball type stems. The NRT conical stem tip stops rotating when it contacts the seat, so further torque turns the stem, but not the tip, preventing damage to the tip.
The HM54 has fully backseated bonnets that prevent accidental stem removal and blowout. This unique design minimizes emissions while offering easy access to the packing.
