Electrohydraulic cylinders are actuation devices that use pressurized hydraulic fluid to produce linear motion and force. A hydraulic pump is an integral part of the cylinder design.
Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves.
Pneumatic lubricators in compressed air lines atomize oil into aerosol form for injection into the air stream to lubricate downstream pneumatic tools, cylinders, motors, and valves.
Pump controllers monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed, output pressure, etc.
