Hydraulics
PLC Direct supplies industrial hydraulics hardware for replacement and maintenance in existing installed systems, stocking valves, pumps, and electrohydraulic control components from established hydraulic manufacturers. Our hydraulics collection covers the hardware used in fluid power circuits across manufacturing, process, and heavy industry environments, supporting customers who need replacement components for installed Vickers, Parker, Rexroth, and Moog hydraulic systems.
Where Are Hydraulics Used in Industrial Environments?
Industrial hydraulics are used wherever high-force actuation, precise fluid power control, or variable pressure and flow management are required in a machine or process system. Hydraulic valves, pumps, and electrohydraulic controls appear in virtually every sector of heavy industry, from discrete manufacturing to continuous process operations and mobile equipment.
Facilities and operations that depend on hydraulics include:
-
Metal forming and press operations where hydraulic cylinders and servo valves provide the force and precision control required for stamping, bending, and forging.
-
Plastics processing machinery, including injection molding and extrusion lines that rely on hydraulic actuators and proportional valves for clamp force and pressure regulation.
-
Oil and gas and petrochemical facilities where hydraulic systems control wellhead equipment, pipeline valves, and process actuators in high-pressure environments.
-
Mining and minerals processing operations using hydraulic power units for crusher drives, conveyor tensioning, and underground equipment actuation.
-
Heavy manufacturing and steel processing plants where hydraulic pumps and directional control valves drive rolling mills, continuous casters, and material handling equipment.
Wherever high-force motion control or fluid power is required in an industrial system, hydraulic valves, pumps, and control components are the hardware that make it work.
Which Brands of Hydraulics Does PLC Direct Stock?
PLC Direct stocks hydraulic hardware from leading fluid power manufacturers for replacement and maintenance in existing installed systems.
-
Vickers DG series directional control valves and V/PVB/PVH series vane and piston pumps: Vickers hydraulic hardware is widely installed across industrial and mobile applications, and the DG series directional control valves cover a broad range of flow and pressure ratings for replacement in existing Vickers hydraulic circuits.
-
Parker Hannifin PRC series hydraulic pressure control valves: The PRC series are pilot-operated pressure reducing and relieving valves rated up to 2,000 PSI for industrial hydraulic circuits requiring precise downstream pressure regulation.
-
Bosch Rexroth VT series analog amplifier modules and proportional hydraulic valves: The VT series amplifier modules provide the electrohydraulic control electronics used alongside Rexroth proportional valves in precision flow and pressure regulation applications.
-
Moog D663 series direct drive servo valves: The D663 series eliminates the pilot stage found in conventional servo valves, providing contamination-tolerant, high-reliability proportional flow control rated up to 4,500 PSI for industrial hydraulic systems, plastics machinery, and die-casting applications.
All hydraulic hardware is available as surplus sealed, refurbished, and used, depending on the specific unit and current stock.
What Should You Know Before Ordering Hydraulics?
Hardware condition options: Surplus sealed units are factory-sealed stock that have not been put into service; refurbished units have been inspected and restored to operational condition; used units are pulled from service hardware. Condition availability varies by part number and should be confirmed at the time of order.
Compatibility and part identification: Hydraulic valves and pumps are specified by pressure rating, flow capacity, port configuration, and mounting interface, and replacement components must match the installed unit across all of these parameters. The part number is typically marked on the valve or pump body and should be used to confirm compatibility before ordering; for Vickers DG series valves, the model code encodes the valve type, spool configuration, and actuation method, while Rexroth VT amplifier modules must match the specific proportional valve they are paired with.
Warranty: All hydraulic hardware purchased from PLC Direct carries a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
PLC Direct supplies hydraulic hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.
