Allows full unrestricted flow of air\n    while in normal (open) position. Entire unit is corrosion free. It automatically re-sets itself after repair is made.\n    Unit is tamper-proof.

Air flow must be in the direction of the arrow\n       marked on the check valve. A safety check valve should be installed for use before each air tool. The actual length of hose from safety check \n    valve to air tool must not exceed a certain length depending upon the inlet pressure (see chart). The volume of air flow (CFM) through an \n    air line will vary according to its length. A longer line will offer more resistance to flow and thus reduce the volume. The length of a hose \n    extending from the safety valve to the air tool must, therefore, be limited to a certain length to insure sufficient flow to trigger the \n    safety valve in case of a break. Check graph for hose length limitations. The closing flow rate (CFM) at various inlet pressure can be \n    obtained from the flow rate chart.\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/td\u003e\n  \u003c\/tr\u003e\n  \n  \u003ctr\u003e\n   \u003cth colspan=\"4\"\u003e\n    Caution:\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n   \u003ctd colspan=\"4\"\u003e\n    \u003cul\u003e\n      \u003cli\u003eDo not reduce safety valve with bushings for use with a smaller air line.
