Anderson Greenwood M4TPVS-4-PT 02-2550-662 Instrument Manifold

The Anderson Greenwood M4TPVS-4-PT (02-2550-662) Instrument Manifold is a rugged two-valve static pressure manifold used to interface a pressure transmitter with a process line, while providing built-in venting and test access to simplify calibration, maintenance, and leak testing in high‑pressure environments. Constructed with a 316 stainless steel body and PTFE packing, it features a 1/2 in FNPT inlet, a flange-style outlet, and two 1/4 in FNPT test ports, enabling secure process connections alongside convenient test and vent paths. The unit is rated for up to 6,000 psi at 200°F (414 barg) and maintains a reduced rating of 4,000 psi at 500°F, reflecting its suitability for demanding instrumentation installs where temperature can influence pressure handling. Typically deployed in differential pressure measurement configurations, it supports reliable isolation and calibration of pressure transducers in industrial process lines, making it a common choice when precise pressure monitoring and safe, accessible service are paramount.
