HYDRAULIC VALVES

Hydraulic Valves, Pumps and Systems.

Hydraulics are widely used in the Lifting and Materials Handling Industries, and offer a compact, High Power to Weight Ratio, Cost Effective source of Power to Raise, Lower and Position Loads.

Hydraulic Power is generated by a Hydraulic Pump, which produces a flow of Fluid at Pressure. This flow and pressure is then supplied to a Hydraulic Actuator which provides the Power to Move and Position a Load.

Hydraulic Valves are introduced between the Pump and Actuator to Control the Load, to Start and Stop movement, Control Direction and Speed of movement, and Force applied.

The combination of Pump, Valves and Actuators is known as a Hydraulic System.

Generally Hydraulic Pumps and Valves are built into a Hydraulic Power Unit, as a self contained unit.

Hydraulic Pumps, are driven by Various Power Sources -

• Hand Pump - Manual Effort.
• Electrically Driven Pumps -
  AC, Single and 3 phase supply (Normally used on Static Equipment) DC, supply from batteries (Normally used on Mobile Equipment)
• Internal Combustion Engine Driven Pumps.
  Air Driven Pumps (Converts a Pneumatic air supply to Hydraulic Power)

Hydraulic Valves

• Pressure Control Valves - Control Force.
• Flow Control Valves - Control Speed.
• Directional Valves - Control Starting, Stopping and Position.
• Load Hold Valves - Supports Load in a fixed position.

Hydraulic valves can be operated by a variety of methods, Electrical, Manually or Pneumatically operated.

Hydraulic Actuators

• Linear Actuators or Hydraulic Cylinders / Rams - Converts Hydraulic Flow and Pressure into a Push / Pull Force.
• Hydraulic Motors - Converts Hydraulic Flow and Pressure into a Rotary Motion.
