Flow control valves with easy-to-read micrometer dials provide a staggering 1100 precise set points to accurately control the flow of gas or liquid. The high CV of the Magna flow control valve enables high flow rates of the 608 series and low flow rates of the 700 or 808 series, suitable for any controlled medium, up to 200 PSIG pressures or full vacuum. Linear flow characteristics provide easy setup and precise gas and liquid metering for almost all applications requiring accurate results.
