Can be used as a safety device in case the fluid line to the fixture could become damaged. Can also be used to prevent workpieces from floating between opposing clamps. The version shown here is manifold mounted, to eliminate exposed fluid lines. Also available with standard fittings for mounting with exposed tubing. Available in one size: Standard capacity (1200 cu.in.\/min flow rate) \u003c\/p\u003e\u003cp\u003e\u003cimg class=\"__mce_add_custom__\" title=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0852\/7223\/2237\/files\/CLR-2951-416_Product_Information_1_jpg.jpg\" alt=\"\" width=\"300\" height=\"300\"\u003e\u003c\/p\u003e\u003ch3\u003eOperation\u003c\/h3\u003e\u003cp\u003eFlow from B \u0026gt; A is free flow.

Due to the unfavourable surface-area ratio of these elements, the control pressure is not sufficient for unlocking and dangerous pressure intensification can occur. \u003c\/p\u003e\u003ch3\u003eMounting \u0026amp; Fluid Supply\u003c\/h3\u003e\u003cp\u003eFluid enters and exits through four O-ring ports fed by drilled fixture passages. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing (32 RMS max). Fasten with four #8 or M4 cap screws. Mount in any position, horizontal or vertical. Do not use NPT fittings. \u003c\/p\u003e\u003ch3 dir=\"ltr\"\u003eParts Specification\u003c\/h3\u003e\u003cdiv class=\"col-md-6\"\u003e\u003ctable class=\"table table-condensed table-striped table-bordered table-primary\"\u003e\n\u003cthead\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e\u003cstrong\u003eSIZE\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e\u003cstrong\u003eMAXIMUM FLOW RATE (cu in\/min)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e\u003cstrong\u003eMINIMUM PILOT PRESSURE (psi)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e\u003cstrong\u003ePILOT FLUID VOLUME (cu in)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e\u003cstrong\u003eWEIGHT (lbs)\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003eCLR-2951-416\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003eStandard Capacity\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e1200\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e.32 x PA + 200\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e.012\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 10px;\"\u003e.55\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Carr Lane","offers":[{"title":"Default Title","offer_id":51721675505965,"sku":"70039806","price":296.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0852\/7223\/2237\/files\/CLR-2951-416_Product_Information_1__34604.png?v=1767057650","url":"https:\/\/allindustrial.mx\/es\/products\/carr-lane-clr-2951-416-pilot-operated-check-valve","provider":"All Industrial Tool Supply Mexico","version":"1.0","type":"link"}
