CV7500 Manual Control Valves Air ranges to 68 LPM, water to 3.55 LPM
DESCRIPTION CV7500 control valves are for low flow OEM, laboratory instrumentation, or bench top flow control applications. The valve designs and material make them suitable for use with a variety of gases and fluids. Complete valves are available in straight through or 90 degree angle body configurations and are constructed of brass or stainless steel. All valves are supplied with 1/8" FNPT inlet and outlet ports.
The economical cartridge valve (CVS) is available in three different needle tapers which cover our entire flow range. These units have a rising stem and provide nine turns from closed to full open.
The precision control valve (CVP) features a non-rising stem and is available in six different needle tapers, for fine control of very low flows. This valve offers sixteen turns from closed to full open. Its design eliminates saw-toothing and is virtually hysteresis free. All materials are matched for similar coefficients of expansion.
