The M1 is a three-valve manifold designed to mount to the signal lines and instrument when the instrument has connections different than 21⁄8-inches [54 mm] between signal taps such as recording orifice meters, small differential pressure indicators and some differential pressure switches.In these applications, the manifold is often supported by the signal lines but may be AGCO Mount supported (-AM). The M1 manifold is available with an integral metal seat or with various replaceable, roddable soft seats. The valve orifice is 3/16-inch [4.8 mm] diameter. The M110 manifold is a high pressure version of the M1 and is available in 316 SS with integral seats.

The MM1 is a miniature three-valve manifold for applications requiring remote mounting from the instrument. Made in CS, 316 SS, or brass, the MM1 features O-ring or packed bonnets with soft or metal seats. This mini-manifold features a unique valve seat which can be converted from soft to hard by simply removing two insert washers. No other parts are required. Used to set or reset differential pressure switches during initial plant start-up. Also used in assemblies for portable differential pressure test equipment used for any miniature differential pressure measuring device.

Designed for remote mounting an instrument via threaded process and instrument connections, the A22N has two block valves, an equalizer valve and two instrument side vent/calibrate valves. Process and instrument side connections are available either 1/4-inch or 1/2-inch threaded. Vent connections are threaded 1/4-inch on all manifolds and provided with blanking plugs. The instrument connections are positioned on 21/8-inch [54 mm] centers but can easily be adapted to suit instruments with other center-to-center dimensions via screwed fittings. Suitable for pressures of up to 6000 psig [414 barg] and temperatures of up to 1000°F [538°C].

The M3A Equalizer Manifold is designed for use with differential pressure transmitters where low-cost direct coupling is desired and piping specifications require individual block valves. The valve is Teflon® -packed and uses a self-aligning SS ball seat. This single valve serves to equalize the transmitter. The M3A fits between the transmitter and the 2-bolt flanges (futbols). For complete mounting, each manifold package includes two Teflon® or GRAFOIL® gaskets and four 7/16-inch – 20 x 21/2-inch zinc cobalt plated alloy steel bolts.

Our M4 Manifold is a three-valve unit designed for mounting on differential pressure transmitters having 21/8-inch [54 mm] center-to-center connections. For direct or remote mounting, the M4A permits the transmitter’s futbol flanges to connect the process signal lines to the manifold directly, with either 1/2-inch pipe or tubing connections. It contains two main block valves and an equalizing valve. For close or remote mounting, the M4T Manifold is used in applications where direct coupling to orifice flanges is not desired. On the instrument side, the M4T bolts directly to the transmitter. On the process side, two 1/2-inch NPT or AGCOTube connections are provided for piping or tubing into the flange taps.

Our M45A manifold is a three-valve unit with 3/8-inch [9.5 mm] orifice block valves designed for mounting on differential pressure transmitters having 21/8-inch [54 mm] center-to-center connections. For direct or remote mounting, the M45A permits the transmitter’s futbol flanges to connect the process signal lines to the manifold directly, with either 1/2-inch pipe or tubing connections. It contains two main block valves and an equalizing valve. Same as M4A except bonnet to accommodate 3/8-inch [9.5 mm] orifice soft seat block valves and metal seat equalizer valve.

The AX3 is a three-valve manifold designed for direct mounting to standard differential pressure transmitters. Lightweight and compact, the manifolds enable instrument operation, isolation and zeroing in a single unit. Process connections are available either threaded 1/4- and 1/2-inch NPT or flanged to accept standard futbol flanges. Suitable for pressures of up to 6000 psig [414 barg] and temperatures of 1000°F [538°C]. AX3 is available metal seated with the option of Teflon® or Graphite stem packing.

The M20 Manifold is a rotary-positioned differential pressure transmitter manifold. It uses a dual-rotary element with passages cut to perform the functions of a doubleblock- bleed manifold, with single handle actuation. The M20 ensures correct valve sequencing every time the manifold is manipulated from RUN-to-ZERO-to-OFF, or from OFF-to-ZERO-to-RUN.

The M24 is a five-valve manifold designed for direct mounting to differential pressure transmitters. Lightweight and with compact dimensions, M24 manifolds enable instrument operation, isolation, zeroing and venting in a single unit. Manufactured from a precision casting with two block valves, an equalize valve and two instrument vent/calibrate valves, the M24 is coupled directly to differential pressure transmitters via standard instrument flanged connections on 21/8-inch [54 mm] centers. (Non-standard instrument centers are also available). Process connections are available threaded or flanged to accept standard futbol flanges. Vent connections are threaded 1/4-inch on all manifolds and provided with vent plugs as standard. Suitable for pressures of up to 6000 psig [414 barg] and temperatures of up to 1000°F [538°C]. M24 is available with a metal seat and the option of Teflon® or GRAFOIL® stem packing.
