This flow control and relief valve is an energy-saving valve that supplies the minimum pressure and flow necessary for actuator drive.
For the High Flow Series, double maximum flow rate [03 size: 125→250L/min (33.03→66.05 U.S.GPM), 06 size: 250→500 L/min (66.05→132.1U.S.GPM), 10 size: 500→1000 L/min (132.1→264.2 U.S.GPM)] enables a smaller valve size than conventional products; compact-sized devices can be provided.
Instructions ：
▲Drain Back Pressure
Check that the drain back pressure dose not exceed 0.2 MPa (29 PSI).
▲When Relief Valve Passing Flow Rate is Low in Pressure Control State
To avoid preselected pressure instability, use a passing flow rate of 15 L/min (4.0 U.S.GPM) or higher.Further, check that the tank-line back pressure dose not exceed 0.5 MPa (70 PSI).
▲Safety Valve Pressure Setting
The pressure of the safety valve is preset at the value equal to the upper limit of the pressure adjustment range plus 2 MPa (290 PSI). Please adjust the pressure of the valve so preset to meet the pressure to be used actually. To lower the pressure setting, turn the safety valve pressure adjustment screw anti-clockwise. After adjustment, be sure to tighten the lock nut.
▲Interchangeability in installation with conventional valves (10 -10 Series)
There is no interchangeability in installation.EFBG-03 A product in the high-flow series can be mounted on the conventional mounting surface but no conventional product can be mounted on the mounting surface of the high-flow series.
