Differential Pressure Manifolds

Used together with a DP transmitter, The manifold comes with either a 3 valve manifold or a 5 valve manifold. The valve is used isolate the DP transmitter from the process for maintenance and calibration.


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

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.

The A26 is a five-valve manifold designed for mounting to differential pressure transmitters. Lightweight and with compact dimensions, A26 manifolds enable instrument operation, isolation, zeroing and venting in a single unit.

More details

The MDP is a five valve manifold designed for direct mounting to differential pressure transmitters. Lightweight and with compact dimensions, MDP manifolds enable instrument operation, isolation, zeroing and venting in a single unit.

More details

The DPM is a five-valve manifold designed for remote mounting to differential pressure transmitters. Lightweight and with compact dimensions, DPM manifolds enable instrument operation, isolation, zeroing and venting in a single unit. 

More details

The MM5 is a five-valve miniature manifold designed for instrument installations where space is restricted. Lightweight and with compact dimensions, MM5 manifolds are designed for flow metering and differential pressure transmitters to enable instrument operation, isolation, zeroing and venting in a single unit.
