Minimum Control Pressure

EPCG2-03 EPCG2-06 EPCG2-10

Notes on Operation

• Air bleedFor stable pressure control, loosen the air bleed plug and bleed air completely out of the valve prior to use.

• Manual adjustmentIn case there is no input current to the solenoid during initial adjustment or electric malfunction, pressure may be set manually with the pressure adjustment knob. Return knob to counterclockwise direction upon electro-magnetic control.

• Minimum control flowPressure setting may be unstable in the case of low flow. Maintain minimum flows above values shown in the table below.

• Drain pipingY port (drain) allowable back pressure is 0.2 MPa. Drain piping should be directly returned to tank. Ensure that end of the piping is always below the fluid level.

• Tank pipingDo not connect with piping of other tanks, each should be directly returned to tank. Ensure that end of the piping is always below the fluid level.

• Vent pipingCare should be paid when the vent line piping is long as the large volume of fluid in the pipes may cause instability in pressure control.

• Zero adjustmentThis is adjusted at factory before shipment. Readjustment is not necessary.

• Main valve setting pressureThe main valve is set at the maximum adjustable pressure plus 2.5 MPa as safety valve (flow is set at 1/2 of max. flow).

• When using the valve mounted on subplate, connect drain from main valve cover Y-port (Rc 1/4).

Mounting Bolts (JIS B 1176, Strength Class 12.9)

• Mounting bolts must be ordered separately.• Mounting bolt tightening torque

EPCG2-03: 72 to 88 N·mEPCG2-06: 90 to 110 N·mEPCG2-10: 180 to 220 N·m

Subplate

• Subplate must be ordered separately.• Hex socket bolts for mounting valve included. (Unified thread)• See page R6-2 for dimensions.Note: When using subplate, care should be paid to working flow and piping

resistance in order to avoid high minimum pressures and poor flow-pressure override characteristics.
