9597 Valve - Inline
LOAD LOWERING VALVE
Application: Precision metering for controlled cylinder piston return.
Operation: Permits free flow when extending cylinder, built-in pressure relief and “Posi- Check®” locks and holds load in raised position until operator opens valve. May be pre-set to provide consistent metered return, or operator may select rate of return with each actuation. Has 3/8" NPTF ports.
NOTE: Pressure relief valve setting is 12,000 psi. Operating pressure is 10,000 psi and max. flow rate is 5 gpm.
No. 9596 – Load lowering valve. Wt., 2.1 lbs.
Application: Used when one cylinder in a multi-cylinder application must advance before any other.
Operation: Pump is connected to port “P” and separate cylinders to ports “A” and “B”. When pressure is applied to port “P”, cylinder “A” advances. Cylinder “B” will not advance until a predetermined pressure setting is reached in cylinder “A”. Pressure setting is adjustable from 500 to 8,000 psi with adjustment screw; factory preset at 1,000 psi. Has 3/8" NPTF ports.
No. 9597 – Pressure control sequencing valve. Wt., 5.6 lbs.
PRESSURE REDUCING VALVE
Application: Provides complete, independent pressure control to two or more clamping systems operated by a single power source. Operation: Can be used to provide different pressures in various stages of a single system. Virtually zero leakage across valve means each system can be operated by a single continuous pressure source. Adjustable from 1,000 to 5,000 psi at outlet port “B” (secondary). Has 1/4" NPTF ports.
No. 9608 – Pressure reducing valve. Wt., 5.8 lbs.
COUNTER BALANCE VALVE
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.
No. 9720 – Counter balance valve, including two male and two female half two hydraulic hoses, fittings and dust caps. Wt., 10 lbs.
No. 9721 – Same as 9720, but does not include couplers, hoses, fittings and dust caps. Wt., 9.2 lbs.
