Hydraulic component

ACTUATOR: A device which converts the energy in a fluid power system into mechanical force. This would typically be a motor, a cylinder, or a rotary actuator.
DIRECTIONAL VALVE: A valve which directs flow or prevents flow through selected ports. A two-way directional control valve has two ports. A three-way directional control valve has three ports, and a four-way directional control valve has four ports.
FILTER: A device placed in a hydraulic circuit to remove small particles and silt from the fluid. Filters can be placed in the suction line (suction strainers and suction filters), in a pressure line (pressure filters), or in the return line (return line filters).
FLOW CONTROL VALVE: A valve used to control the amount of flow entering or leaving a segment of the hydraulic circuit. Pressure compensated flow control valves have a constant flow rate regardless of operating pressure, while the flow through non-pressure compensated flow control valves may fluctuate as the pressure
PUMP: A device which when driven by a prime mover will draw low pressure fluid into an inlet port and push high pressure fluid from an outlet port. A pump can be a hand or air operated linear device, or a rotary device that uses gears, vanes or pistons to move the fluids.
RESERVOIR: A container that holds fluid. A reservoir in an industrial fluid power system typically holds three times as much fluid as the pump's capacity (a 60 gallon reservoir for a 20 gpm pump), has a baffle separating the suction and return ports, has a clean-out port and a filtered filler/breather cap.
PRESSURE REDUCING VALVE: A valve which reduces the pressure in a particular portion of the circuit by venting a small amount of fluid back to the reservoir.
COUNTERBALANCE VALVE: A valve commonly used to balance the weight of a dead load by creating a back pressure in the system cylinders that is high enough to support the weight.
CHECK VALVE: A two port valve that allows flow in only one direction
TANK: Also called a reservoir. A container that holds fluid. A reservoir in an industrial fluid power system typically holds three times as much fluid as the pump's capacity (a 60 gallon reservoir for a 20 gpm pump), has a baffle separating the suction and return ports, has a clean-out port and a filtered filler/breather cap.

THREE WAY VALVE: A valve which has three ports - typically one inlet port and two outlet ports. The inlet port is the pressure port. One of the outlet ports is normally open (flow is allowed through) and the other outlet port is normally closed (no flow allowed).

TWO WAY VALVE: A valve which has two ports - normally an inlet port and an outlet port. Two way valves are used to open or close a flow passage and can be configured as normally closed (no flow through the valve) or normally open (fluid flows through the valve).
RELIEF VALVE: A valve which limits the maximum pressure in the system by dumping fluid from the high pressure line to a lower pressure line when the pressure setting of the relief valve is reached. SEQUENCE VALVE: A pilot-operated two-way valve that is pilot operated and shifts when the pilot pressure reaches a preset pressure level. Sequence valves are normally used to start a secondary set of operations.
