Anderson Greenwood (AGCO) M4A, M4T Three-Valve Differential Pressure Instrument Manifolds

In Stock Options

The TESCOM™ AGI / AGCO / Anderson Greenwood M4A and M4T three-valve manifolds have two main block valves and an equalizing valve for direct or remote mounting at pressures to 6,000 psig (414 barg). The AGCO M4A is designed for mounting on differential pressure transmitters with 2 1/8″ (54mm) center-to-center connections. The AGCO M4T is used in applications where direct coupling to orifice flanges is not desired.

Optional soft-seated bonnet assemblies have a one-piece rotating stem and plug, available with an FKM O-ring and PTFE back-up ring in addition to the adjustable PTFE packing gland. Metal-seated bonnet assemblies use a rotating stem with a free swivel ball-type seat for long service life, with a specially hardened ball seat ideal for both gas and liquid service.

Features
