The Model 13110 Proportional-Speed Floating Hydraulic Controller is designed for applications where a group of controllers are supplied from a separate, but common power supply. The controller has a practical output range of approximately 235 to 45,000 pounds of force at the actuator. Model 13110 accepts pressure, differential pressure or electric signals.

The Model 13120 Hydraulic Controller (servo valve) is specifically designed for any control system applications that require high performance hydraulic control or continuous servo valve actuation. The Dynaguide* Hydraulic Controller accepts electrical or pneumatic signal inputs from primary sensors. This signal is converted into a powerful hydraulic signal, through the use of an integrally mounted moving coil or diaphragm assembly and a jet pipe nozzle.

The Model 19111 is a complete Hydraulic Pump Unit consisting of pump, motor, 30 gallon reservoir and necessary accessories. Designed primarily for hydraulic controller application, it can be used wherever hydraulic power is required.

Model 14130 Crank Type Cylinders accept hydraulic oil to produce a rotary motion 90 degrees maximum. The models consist of a linear motion cylinder and a linkage which connects to a rotary motion.

Model 14140 Crank Type Cylinders accept hydraulic oil to produce a rotary motion (90 degrees maximum). The models consist of a linear motion cylinder and a linkage which connects to a rotary motion.

The Model 31490 Rotary Position Transmitter is a potentiometer type transmitter which transmits field information to a remote point. The Model 31490 Rotary Position Transmitter is used principally as a feedback for valve actuators. The 31490 accepts a shaft position and produces a 4-20mA electrical output signal over a 2 wire system. The signal from shaft rotation is produced by a potentiometer. The shaft of the potentiometer is connected to the transmitter input shaft through a stepdown gear. The 4-20mA is generated by a constant current generator. The transmitter is housed in an aluminum, weatherproof and explosion proof housing built to Class I, Division I, Group D requirements of Factory Mutual. Temperature Range is from -30°F to +140°F.

GPE Controls Model 31590 Position Transmitter is a heavy-duty assembly packaged for industrial on-line applications. Electrically, it is a rotary potentiometer, but mechanically it is built withstand rugged environments and translates linear motion into rotary motion. The Model 31590 Linear Position Transmitter is used principally as a feedback for valve actuators. This unit can be used in many applications on moving web processes, such as sensor following feedback and final control element feedback.
