VALVE SETTING
Type J valve can be set by client. Calibration requires a pump, a pressure gauge (to measure the
pressure), a shut-off valve and Type J valve.
Start up the pump with the shut-off valve in the closed position. The liquid will pass through the Type J
valve, which will act as a bypass (recirculation). Tighten the top screw (previously loosening the lock nut)
on the TypeJvalveuntilthepressuregaugeindicatesthepump’smaximumworkingpressure.Thevalve
will then be set to the pressure indicated on the pressure gauge; if this pressure is exceeded, the valve
will close and the flow will be recirculated, thus preventing any damage to the system.
