Anderson Greenwood (AGCO) M1, M110 Three-Valve Differential Pressure Manifolds

The AGCO / Anderson Greenwood M1 three-valve manifold serves differential pressure transmitter installations with the option of metal or roddable soft seats; the high pressure all stainless AGCO M110 has integral metal seats.

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. The high pressure M110 bonnet assemblies use a strengthened stem and bonnet fitted with a larger T-bar handle, and the M1’s high-temperature bonnet assemblies incorporate adjustable graphite O-rings and back-up pressure rings to ensure a leak-free stem seal.
