Proportional valves

Multitasking proportional valves are equipped with electronic circuitry and sensors that control both pressurize and exhaust and can be set to operate within particular electrical values (0 to 0 V or 4 to 20 mA). The sensors automatically adjust after the eighth cycle. The valve offers varied operating positions (from 0 to 100%) and provides complete adjustability and repeatability. Electronic and sensing controls ensure level pressure even when dealing with faulty system seals, component wear, pressure drops, varying electrical supply, and other challenges. It functions as an integral pilot or power valve.Ross Controls, 1250 Stephenson Highway, Troy, MI 48083, (800) 438-7677, www.rosscontrols.com
