Differential Pressure Manifolds - M4A and M4T 3-Valve ...

1 Anderson Greenwood Manifolds Catalog Flow, Static Pressure , and Liquid Level Manifolds Differential Pressure Manifolds - M4A and M4T 3-Valve Manifolds Fugitive emissions. To meet low fugi- tive emissions requirements, special Graphite sealed bonnets are available. Fewer parts means fewer leak points which mean fewer fugitive emissions. Manifold mounts directly to the pipestand. The AGCO Mount sup- ports the transmitter and allows loop installation to be completed without the transmitter. Instrument removal for service or repair does not disturb M4T installation. M4A. Teflon , GRAFOIL , or Graphite packing adjusts easily. Decreases downtime and increases valve life. Integral hard back seat protects against stem blowout and forms a secondary seal. Product Overview Protective bonnet cap (Teflon.)

Rolled threads provide additional thread strength because the stem and bonnet threads are rolled, not cut. 1998, Rev. 1999 Anderson Greenwood Instrumentation Products reserves the right to change product designs and specifications without notice. 64.
