Hydraulic Proportional Control Valve

Improve productivity and quality.

Hydraulic proportional control valve.

How it works hydraulic proportional valve. Offers design products and systems for all three types. Directional proportional and servo valve control systems. Reduce commissioning time through plug and play functionality.

Here the throttle measuring throttle in the form of a 2 2 way or 4 2 way valve is actuated by a proportional solenoid. A proportional throttle valve in the pump line of figure 14 11 controls flow to a standard solenoid valve. Quality hydraulics pneumatics inc. Understand the different types of valve that are available their function and where they are used.

A solenoid is essentially an electro mechanical device consisting of a ferrous metal core inside a copper winding called a coil. When an electrical current passes through the copper coil it creates a magnetic field. With over 60 years experience producing servo and proportional valves for the industrial market our products are legendary for reliability. Proportional pressure control valves have proven their reliability time and time again in literally millions of operational hours.

This circuit is good for resistive loads only because it meters fluid to the cylinder. Moog is a leader in designing manufacturing and selling high performance hydraulic valve products. From multiple direct to pilot operated proportional pressure control valves this range delivers a wide range of hydraulic flow capacity for any relieve circuit. Proportional pressure control valves.

Our valves offer extremely high response up to 300 hz and are offered with or without on board control electronics. To reduce energy waste use a load sensing pump and sense the line between the proportional valve and the directional valve. In the context of oil hydraulics a solenoid valve can be either of spool or poppet construction. Proportional valves are increasingly fitted with electrical feedback proportional flow valves as in conventional hydraulic systems there are throttle valves figure p 27 and 2 way and 3 way flow control valves.

A proportional control valve system can be used to improve control of most machines without the high price tag of servo control systems. Servo valves are closed loop control devices that can be single stage two stage or three stage designs. Reduce labor time and costs by minimizing wiring. Parker proportional valves employ powerful voice coil valve technology which allows higher flows from smaller valves.

Proportional valves are only used relatively infrequently as their function is mostly performed by proportional directional valves.
