Pneumatic Proportional Control Valve

Our pneumatic proportional flow control valves handle flow conditions from less than 1 liter per minute lpm up to 400 lpm.

Pneumatic proportional control valve.

The function of proportional valves falls into a wide spectrum somewhere between on off solenoid valves and electrohydraulic servo valves. Control the pressure for connected pneumatic loads. Figure 14 9 depicts a proportional valve used for a throttle function. We offer a range of functions including open and closed loop control fail freeze and atex options.

The flowtronic d features software with many features including control loop customisation so the valve can be tuned to the application. Quick easy online ordering. Proportional pressure control valves. Our process control valves are versatile for various.

Our valves cover the complete performance range from standard up to maximum dynamics. Proportional control valves or electronic regulators can control compressed air gas liquid and vacuum. Control the pressure for connected pneumatic loads. Max pressure is 200 pounds per square inch gauge psig for standard units unless you choose our pressure compensating valve.

Offers design products and systems for all three types. They convert a variable current or voltage signal into a proportional compressed air output. Industrial and mobile hydraulic proportional valves enable a precise directional or flow control. Featuring a wetted path made of 300 and 400 series stainless steel and fkm epdm and ffkm seal options pfv proportional solenoid valves flow not only air and water but also the most challenging media.

Quality hydraulics pneumatics inc. Digital controller for proportional solenoid valves control d is a pid controller that controls the current to a solenoid coil making any solenoid valve respond proportionally to an electrical control signal. Numatic engineering is your premier resource for pneumatic automation components solutions and services unlike directional control valves which produce full flow when energized proportional control valves produce pressure or flow proportional to an electrical signal. A proportional valve may have feedback control but the response time of the valve is too slow to get the precise control that a servovalve circuit provides.

Pfv liquid and gas 2 2 proportional solenoid valves simplify design and construction of medical life science semiconductor and other oem equipment. The kelly proportional valve range. Proportional valves are sometimes referred to as i p or e p convertors. Parker s proportional valves employ powerful valve technologies and are well suited for a variety of applications where accuracy and efficiency are a must.

Direct solenoid operated proportional throttle valve without lvdt. A proportional control valve system can be used to improve control of most machines without the high price tag of servo control systems.
