Tank-Line back pressure
Check that the tank line pressure does not exceed 0.2MPa (2.0kgf /cm²)
When this valve is used as a relief valve or for other valve vent control purposes, use 6 mm ID, 300mm long or shorter pipes for piping connections, If pressure instability is encountered, provided a 1-1.5mm diameter orifice for the relief or other valve vent port.
Circuit Pressure Control
When circuit pressure is directly controlled by this valve, make sure that the trapped oil volume is exceeding 40cm3.
Low Flow Rates
The preset pressure may become unstable. To avoid such pressure instability, the flow rate should not be lower than 0.3 L /min.
Safety Valve Pressure Setting
The safety valve pressure setting at the maximum flow rate is preset to a level that is 2MPa( 20.4kgf /cm² ) higher than the pressure adjustment range upper limit. If the operating pressure upper limit is low or a different flow rate upper limit is used, make adjustment after calculating the safety valve pressure setting from the following equation; Pressure setting＝(Operating pressure upper limit )＋(Additional pressure indicated right )
