Counterbalance Valves and Manifolds

Counterbalance valves control lowering and hold the load, on hydraulic winches, motors and cylinders. Manifold blocks are designed from the circuit diagram.

Valve functions: Relief, check, counterbalance, flow control, directional
Material: Aluminum, steel, ductile iron
Testing: Pressure, leakage, function

Hydraulic power supply

Power Units

Power for motors, cylinders and winches, and for brake release, lubrication and cooling circuits. Tank, pump and valves are sized to the actuators and duty.

Components: Electric motor, pump, tank, manifold, filter, cooler
Power supply: Voltage and power to suit the machine
Control: Manual, electric, sensor feedback, PLC

Ask about a power unit

Match valves and power units to the circuit

Do not swap counterbalance valves or manifolds casually. Different flow, cracking pressure, circuit and load behavior can cause shaking or runaway when lowering. Send the circuit diagram, or describe the motions you need.
