Hydraulic Pump

Daikin - Daikin VZ Series Piston Pump

These pumps realize highly intensified outputs by adopting a cradle swash plate. Products in the range from 50 to 130 cc/rev are brought together as a series.

Daikin - Piston Pump

These are the standard variable displacement piston pumps. Products characterized by low noise, high efficiency and high reliability are brought together in a series covering the range from 8 to 70 cc/rev.

Nachi - Small Variable Volume Vane Pump

These solid, long-lasting, compact pumps are of simple design, precision manufacturing, and deliver powerful, high-pressure capabilities. On/Off and Off/On response is immediate. Noise is reduced, vibration and power loss are minimized. These simple vane pumps work well in a wide variety of hydraulic applications.

Hydraulic Valve

Moog - Flow Control Servo Valve

The G631 series flow control servovalves are throttle valves for 3- and preferably 4-way applications. They are a medium performance, two-stage design that covers the range of rated flows from 1.0 to 20 gpm at 1,000 psi valve drop. The output stage is a closed center, four-way sliding spool. The pilot stage is a symmetrical doublenozzle and flapper, driven by a double air gap, dry torque motor. Mechanical feedback of the spool position is provided by a cantilever spring. The valve design is simple and rugged for dependable, long life operation. These valves are suitable for electrohydraulic position, speed, pressure or force control systems with high dynamic response requirements.
