VM-3 and VM-5 valve manifolds ¸ Body material – steel (316 ss)
VM-3 valve
VM-5 valve Features
3-val ve and 5-valve manifolds are used where relative pressure transmitters are installed. They enable essential operations to be performed on the transmitters, such as starting up a transmitter or setting the zero position in con ditions of static or atmospheric pressure. The five-valve manifold also enables a calibrato r to be connected for metrologi cal testing of the transmitter. The VM-3 and VM-5 have a modern lightweight construction. The hi gh precision of manufacture enables individual valves to be opened and closed easily.

Recommendations concerning selection of valves
The standard versi ons of the valves have Teflon pin packing; a special version is available with graphite packing. The special version should be used only when the valves operate at temperatures in excess of 2 00°C. The valve manifold is su pplied with seals for the collar-type output points. 7 To order, i t can be supplied additionally with a set of M10 or / 16 " (stainless steel) screws fo r fitting the transmitter, connectors for impulse lines and a sheet-metal handle used to mount the valve on the construction.
