Such aninstallation will double the maximum and minimumflows.APRESSURE DROP (PSI)10090807060504030201098765<strong>802</strong>-GPM 28 39 54 66 80 91 103<strong>802</strong>-LPM 106 148 208 247 303 341 388MINIMUM FlOW <strong>802</strong>*MAXIMUM FlOW <strong>802</strong>TYPICAL SPECIFICATIONMaster water mixing valve shall be of the thermostatictype with liquid filled thermal motor. It shallhave bronze body construction with replacablecorrosion resistant components. Valve constructionshall employ a sliding piston controlmechanism. Sliding piston and liner shall be ofstainless steel material. Valve shall come equippedwith union end stop and check inlets with removablestainless steel strainers. Valve shall controltemperature from a low flow of 2 GPM* up to amaximum flow rate for a given pressure differential.Valve shall provide protection against hot or coldsupply line failure and thermostat failure.4321 2 3 4 51020 30 40 50 60 70 80 90100AllOWABlE FlOWSMAXMINFlOW (gPM)<strong>MODEL</strong> <strong>802</strong> FEATURES• Built with a powerful liquid thermal motor.• Compensates for supply line temperature andpressure changes.• Outlet flow is greatly reduced upon supply lineor liquid motor failure.• Inlets are fully rotatable through 360° and outletis rotatable through 360° in 90° increments.Full flexibility is provided for roughing in thevalve.• Tamper-resistant control adjustment.• Rugged design equipped with stainless steelpiston and liner.*1/ 2 gpm when properly installed in recirculated system.• Easy maintenance valve can be completelyrepaired without being removed from the system.
