The 7MF9411-5.. 2-spindle, 3-spindle and 5-spindle valve manifolds are for pressure transmitters for absolute pressure or differential pressure.
The valve manifolds are used to shut off the differential pressure lines and to check the pressure transmitter zero.
The 2-spindle and the 5-spindle valve manifold also enable venting on the transmitter side and checking of the pressure transmitter characteristic.
