Please note that when the product is shipped from the factory, gases such as and air may leak from the valve at a rate of cm /min (when pressurized).. When operated at a very low flow rate, the series LQ with flow rate adjustment may vibrate, etc. depending on the operating conditions. Therefore, operate it after careful examination of the flow rate, pressure and piping conditions.. In the series LQ, water hammering may occur depending on the fluid pressure conditions. In most cases, improvement is possible by adjusting the pilot pressure with a speed controller, etc., but the flow rate, pressure and piping conditions should be reviewed.. To adjust the flow rate for the series LQ with flow rate adjustment, open gradually starting from the fully closed condition. Opening is accomplished by turning the adjustment knob counter clockwise. dditionally, do not apply any unreasonable force to the adjustment handle when nearing a fully opened or closed state. This may result in deformation of the orifice sheet surface or damage to the threaded part of the adjustment handle. It is in the fully closed condition when the product is shipped from the factory.. fter a long period of nonuse, perform a test run before beginning regular operation.. Since the LQ is packaged in a clean room use sufficient care in handling when opened. W Q X X X X L L LH L LQ LQ L TI/ TIL P PX P --89
