{"product_id":"conrader-rc-series-pilot-valve-manual-hand-unloader","title":"Conrader RC-Series Pilot Valve with Manual Hand Unloader","description":"\u003cp\u003eThe Conrader RC-series pilot valve is a factory-set pressure control valve with a manual hand unloader lever, used on air compressors and compressed-air systems to switch a downstream device on a pneumatic signal. As tank pressure rises to the unload (cut-out) setting, the pilot opens and pressurizes the line downstream; as pressure falls to the load (cut-in) setting, the pilot closes and vents that line. This cyclic signal is what drives an unloader valve, throttle control, drain valve, or shuttle valve. The hand unloader lever makes for easy, low-load engine starting and can be swapped for a dual-control lockout on electric-motor compressors to switch between start\/stop and continuous running.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating pressure:\u003c\/strong\u003e 20–250 psi (RCL-S rated to 1200 psi)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating temperature:\u003c\/strong\u003e -15° to 400°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody:\u003c\/strong\u003e brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl:\u003c\/strong\u003e manual hand unloader (HU) lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection types:\u003c\/strong\u003e Male or Female NPT, depending on configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e factory-set cut-in \/ cut-out pilot signal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChoose your port configuration\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCB-HU\u003c\/strong\u003e — 1\/4\" FNPT inlet × 1\/8\" FNPT outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCBM-HU\u003c\/strong\u003e — 1\/4\" MNPT inlet × 1\/8\" FNPT outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCT-HU\u003c\/strong\u003e — 1\/4\" FNPT inlet × 1\/8\" FNPT outlet, cross body\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCQ-HU\u003c\/strong\u003e — 1\/4\" FNPT inlet × 1\/4\" FNPT outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCLS-HU\u003c\/strong\u003e — 3\/8\" FNPT inlet × 1\/4\" FNPT outlet (high-pressure RCL-S series)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eRegulating engine speed through a throttle control, loading and unloading a compressor, draining condensate, and operating normally open\/closed or shuttle valves on gas-engine and electric-motor driven compressed-air systems.\u003c\/p\u003e\n\u003cp\u003eThe Conrader RC-series pilot valve with manual hand unloader is a proven, rebuildable brass control for keeping compressor cut-in and cut-out pressures consistent.
