Electro-proportional controlled cushion lock assembly - XCCLLANAI224 · 模型 123788
This valve assembly provides independent, proportional meter-in speed control for ports A and B, overrunning load control, and load-port relief protection. It also supplies make-up oil and flushes hot dirty oil out of the actuator. All oil coming out of the actuator returns to tank through port T. The counterbalance valves should be set at 1.3 times the maximum load induced pressure. The term cushion in the name Cushion Lock is a misnomer. Because the counterbalance valves play a dual role as load controls and work port reliefs they must be set too high to provide any real cushion. Deceleration can only be achieved by ramping down the input flow. This assembly is ideal for applications with long lines to the actuators. Mounting the assembly close to an actuator ensures that cool, clean oil will be supplied to the actuator and that the hot, dirty oil will go out the T port to the tank Low pilot ratio counterbalance valves (3:1 vrs 10:1) may be necessary to generate enough pressure to release a brake. Hydraulic motors leak. Therefore a mechanical brake is recommended to positively lock any stopped live load. Includes mounting threads 8-32 UNC-2B x .28 (7 mm) deep for optional XMD driver. When not configured with cartridge, the XMD driver must be purchased separately. A harness will be required.
