- Tank-Line back pressure
Check that the tank line pressure does not exceed 0.2MPa (2.0kgf /cm²)
- Vent Control
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 )
