Circle Seal PVR-2PM-CV Valve

Circle Seal PVR-2PM-CV is a panel-mount, 1/4 in NPT low-pressure regulator in Circle Seal Controls’ PVR series, designed to accept up to 3,000 psi inlet and deliver a precise 2–6 psi outlet. The valve’s PVC body houses a Kel-F seat paired with a synthetic sapphire ball and PTFE (Teflon) seals, and it has a flow coefficient (Cv) of 0.011 to support stable, low-flow regulation across its operating range of 0 to 125°F (-18 to 46°C). Ports are 1/4 in NPT female on both inlet and outlet, and the PM designation confirms a panel-mount configuration suited for compact installations in instrumentation panels or enclosed systems. Circle Seal describes the PVR series as providing exceptional accuracy and response for regulating corrosive and non-corrosive media, making the PVR-2PM-CV a suitable choice when tight pressure control is required in demanding environments. Applications include panel-mounted gas lines in analytical equipment, chemical processing, and laboratory instrumentation where reliable 2–6 psi control from a 3,000 psi source is essential.
