VM-3 and VM-5 valve manifolds are utilized with pressure transmitters. These valves allow operations to be carried out on the transmitters, like the initiation of a transmitter operation or adjusting a zero dimension in case of static or climatic pressure.
Additionally, the five-valve manifold offers a calibrator, the capability to connect for a metrological test for the transmitter.
The units can rev up up to 420 bar of maximum pressure and has Graphite pin packing. They are relatively light weight - the VM-3 weighing 1.8 kg and the VM-5 with 2.54 kg.
