Manual control valves for extremely precise control of a constant-flow rate

The new FLOW-CONTROL manual control valves are designed for extremely precise control of a constant flow rate in low flow gas and liquid applications. The desired flow rate is set via the needle valve. Any upstream or discharge pressure variations are automatically compensated by a built-in membrane operated valve to ensure a steady, constant flow. Thanks to its thought-out design and construction, these instrument models do not require any electrical power source.

The manual constant-flow control series is available in 4 different models to control flow capacities in a range from 0.02 ln/min up to 50 ln/min (N2-equivalent) and 3 up to 1800 ml/min for water. While process connections are optional available, the in-line valve assemblies are equipped with G 1/4” BSPP female in- and outlet ports.
