> Introduction Bronkhorst®, the European market leader in thermal Mass Flow Meters/Controllers and Electronic Pressure Controllers, has many years of experience in designing and manufacturing precise and reliable measurement and control devices. With a wide range of instruments, Bronkhorst offers innovative solutions for many different applications in many different markets. > FLOW-CONTROL series 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). While process connections are optional available, the in-line valve assemblies are equipped with G 1/4” BSPP female in- and outlet ports. Features of constant-flow controller Compact design Ruggedized aluminium housing No power required Leak-free valve Valve pin o-ring guarantees positive shut-off without stem damage Self-lubricating orifice liner assures long life Valve knob included for easy adjustment
