Pneumatic Proportional Control Valve

They convert a variable current or voltage signal into a proportional compressed air output.

Pneumatic proportional control valve. 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. Proportional control valves or electronic regulators can control compressed air gas liquid and vacuum. Our pneumatic proportional flow control valves handle flow conditions from less than 1 liter per minute lpm up to 400 lpm. Direct solenoid operated proportional throttle valve without lvdt.

The flowtronic d features software with many features including control loop customisation so the valve can be tuned to the application. Pfv liquid and gas 2 2 proportional solenoid valves simplify design and construction of medical life science semiconductor and other oem equipment. 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. Proportional pressure 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. Industrial and mobile hydraulic proportional valves enable a precise directional or flow control. 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. Control the pressure for connected pneumatic loads.

Quick easy online ordering. 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. Our process control valves are versatile for various. Parker s proportional valves employ powerful valve technologies and are well suited for a variety of applications where accuracy and efficiency are a must.

Control the pressure for connected pneumatic loads. Quality hydraulics pneumatics inc. We offer a range of functions including open and closed loop control fail freeze and atex options. Proportional valves are sometimes referred to as i p or e p convertors.

Offers design products and systems for all three types. Figure 14 9 depicts a proportional valve used for a throttle function. Pneumatic flow control valves circulate air and gases throughout a larger pneumatic system by either allowing or inhibiting the flow of pressurized air. Directional proportional and servo valve control systems.

Max pressure is 200 pounds per square inch gauge psig for standard units unless you choose our pressure compensating valve. The kelly proportional valve range.
