WITT Gasetechnik GmbH presents precision metering valve with sintered body


WITT, manufacturer in the field of gas safety and gas process technologies, presents the precision metering valve (PMV).

Its spindle with 14 full rotations is generously sized to allow very fine flow gradations and has virtually no hysteresis. An alternative is a digital knob with 1499 divisions and a locking ring, this allows any target value to be set rapidly, precisely and with high repeatability.
