The circuits show a standard counterbalance valve as a bypass on a cylinder activated by the pressure for a hydraulic saw or drill motor.
- Standard counterbalance valve: CB**
- Ventable reducing relieving valve: PV*B
Benefits of this circuit arrangement:
- Fig.1 The motor may be for a drill or a saw. The speed of the feeding cylinder is reduced when the pressure to drive the motor exceeds a pressure that is adjustable on the counterbalance valve. A variety of counterbalance valves are offered to allow stable interaction between two circuits.
- Fig.2 The counterbalance valve can also control a pressure-reducing valve type PV*B to control the feed/clamping cylinder.
