Precautions for Use

l The back pressure at the oil return port must not exceed 0.5 MPa.

l The oil return pipe should directly return to the oil tank and must not be connected to the oil return pipes of other valves.

l When adjusting the pressure regulating handle, turn clockwise to increase the pressure and counterclockwise to decrease it. Be sure to tighten the fixing nut after pressure adjustment.

l When the flow rate is small, the set pressure is prone to instability. For specifications 04 and 06, use a flow rate of more than 8 L/min; for specification 10, use a flow rate of more than 15 L/min.
