INTRODUCTION Back Pressure Valve: Generally, the back pressure valve can be installed anywhere in the discharge line, provided there is some downstream pressure at the dosage point. If there is no downstream pressure the back pressure valve should be installed at the dosage point to prevent siphoning and drainage of the chemical line. The valve can be installed either vertically or horizontally. All GRIFFCO valves are factory set at 50 psi, unless otherwise specified.
