• Proportional Pressure Control Valves allow total control of pressure or force requirements
• True centering spring brings valve to safe position in the event of failure
• Easy to Set Up  Electronic Amplifiers – On Board L.E.D. Simplifies Startup and Adjustment
• Can Be Interfaced with Input Signals from Transducers, PLC’s, Computers, Joysticks and Potentiometers

Product Description

Proportional Control Valves are controlled by electronic Amplifier control boards, and are commonly called electro-hydraulics. These Proportional Valves control direction and the amount of fluid flow or can control the amount of pressure within a system.

Electro-hydraulic controls are especially useful in situations where system speed must be tightly controlled, or where ramping up and down is needed to avoid sudden starts or stops. Electro-hydraulics also provides precise control in applications where hydraulic pressure must be built up steadily.

Continental Hydraulics Proportional products can help increase production and reduce down time by minimizing the shocks that occur from sudden changes as compared to standard components.

In conjunction with precision valves, Continental Hydraulics provides Electronic Control Amplifier Cards. These Amplifiers come in a variety of mounting styles, signal conditioning, PWM and Dither, Acceleration and deceleration limiting and current sensing circuitry to work with and accurately control proportional products whether in open or closed loop systems.
