4-way/3-position (tandem center) solenoid valve with Posi-CHeck

Application:Double-acting cylinders.

Actuation:Solenoid operated, 115 volt, 50/60 Hz.

Functions:Push button control of advance, hold and return. The Posi- Check feature guards against pressure loss when shifting from advance to hold. With valve in hold position, cylinder ports are blocked and oil is directed from pump to reservoir.

NOTE:Consult factory before installing a pressure switch on any of these valves.

CAUTION:To prevent sudden, uncontrolled descent of a load as it is being lowered, use a Load Lowering Valve (No. 9596) or Counter Balance Valve (No. 9720) in conjunction with the directional valve used in your application.

CAUTION:The Posi-Check feature will not hold the load when shifted directly A to B-B to A or from hold to A or B.

NOTE:Maximum tank line pressure for remote mounted valves is 500 psi.

Application:Single or double-acting cylinders. Permits adjusting operating pressures at various values below relief valve setting of pump.

Operation:Regulator valve is easily adjusted to maintain pressures between 300 and 10, 000 psi. Maintains a given pressure setting within 3% over repeated cycles. Flow range is 17 cu. in./minute to 6 gpm.

Simply turn the handle clockwise to increase the pressure setting, counter-clockwise to reduce pressure.

NOTE: 3' Drain Line Kit is Included.

Application:Single or double-acting cylinders.

Actuation:9593, 9524 and 9554 are solenoid operated.

Operation with single-acting cylinder:Either oil port A or B must be plugged on valve. With port B plugged, solenoid is energized to position A, oil port A becomes pressurized. When solenoid is energized to position B, oil port A becomes the return port.

Operation with multiple single-acting cylinders:A pressure line from one bank can be connected to oil port A and the other to oil port B on the valve. Sequence: When energized to position A, oil port A becomes pressurized and clamps the fixture connected to oil port A; oil port B becomes a return port for cylinder connected to oil port B, and retracts it. The opposite happens when solenoid B is energized.

Operation with double-acting cylinder:Port A is connected to advance port of cylinder, oil port B connects to cylinder return port. Solenoid is energized to position A, oil port A becomes pressurized to extend cylinder piston. The opposite happens when solenoid B is energized. Valve does not hold in retract position.

NOTE:When using more than one valve on a pump, the tank port may require a check valve (9580)to permit inadvertent, momentary extension of a retracted cylinder.

NOTE:If pump is equipped with an internal outlet check, a hold position can be maintained with the pump shut off.

NOTE:Valves are shipped without control switch.
For valves 9524, 9554 and 9593, use Remote Hand Control (No. 304718).
For valve 9595, use Remote Hand Control (No. 209593).

NOTE:Valves have 1/4" NPTF ports. 3/8" to "1/4" adapters are included.

NOTE:Maximum tank line pressure for remote mounted valves is 500 psi.

NOTE:Valves are shipped without control switch. Use Remote Hand Control (No. 202777).

CAUTION:To prevent sudden, uncontrolled descent of a load as it is being lowered, use a Load Lowering Valve (No. 9596) or Counter Balance Valve (No. 9720) in conjunction with the directional valve used in your application.

Application:Double-acting cylinders. Provides positive holding and controlled, chatter-free lowering of a load.

Operation:Load is raised at flow rate of pump, and held when pump is shut off. When the pump is shifted to retract, the counter balance valve will continue to hold the load until system pressure exceeds pressure caused by load. The load can then be lowered smoothly to the flow rate of the pump. The counter balance valve is designed to operate with pumps having a high pressure flow rate of up to 120 cu. in./min. and cylinder ratios of 3 to 1.

CAUTION:The 9720 patented counter balance valve has a pilot pressure as high as 3, 000 psi. Because this pressure is applied to the rod end of the cylinder while it is already under load, the system should not be sized for loads greater than 80% of cylinder rated capacity.

CAUTION:To prevent sudden, uncontrolled descent of a load as it is being lowered, use a Load Lowering Valve (No. 9596) or Counter Balance Valve (No. 9720) in conjunction with the directional valve used in your application.

Application:Single or double-acting cylinders. For remote locations in a hydraulic circuit where maximum pressure requirements are less than basic overload valve setting in pump.

Operation:Adjustable from 1, 000 to 10, 000 psi. Valve is spring-loaded and direct-acting.

Application:For use with open or tandem center valves. Permits free flow of fluid in one direction.

Operation:Flow is blocked in opposite direction until pilot oil pressure is applied. This prevents the loss of pressure if the valve is inadvertently shifted or the pump line is broken. Minimum cracking pressure is 60 psi. Required pilot pressure is approximately 16% of checked system pressure.

Application:This needle valve permits fine metering of hydraulic oil.

Operation:Can be used for controlling multiple single-acting cylinders.
