Air Flow Electronic Pressure Valves and Regulators

electronic pressure regulators

Electronic Pressure Regulators

Proportion-Air designs and manufactures electronic pressure regulators for a wide variety of applications. Pressure controls are available for very low pressure applications (down to 0-4 inches H2O column), very high pressures (up to 1000psi direct electronic control), high flow rates (up to 4 inch pipe), ultra high resolution (0.004% FS resolution), intrinsically safe (Factory Mutual Class 1 Div 1 and Class 1 Div 2), and low cost OEM style pressure controls.

electronic flow controls

Electronic Flow Controls

Proportion-Air manufactures two types of flow control valves; closed loop mass flow control valves and open loop variable orifice flow control valves. The F-series mass flow transducer is the heart of the closed loop models. The F-series calculates flow based on differential pressure which results in very fast flow measurements. This flow can be connected to Proportion-Air’s pneumatic control valves as a feedback loop for closed loop control. The FCV (Flow Control Valve) is a variable orifice angle seat design. The FCV closes the loop around internal valve position with an integral LVDT. The position of the valve directly correlates to valve flow capacity (Cv) based on careful design of the parabolic valve plug geometry.

Custom Products and Custom Solutions

Proportion-Air builds only electronic pressure and electronic flow control valves. Each control valve we build is carefully selected based on each customers unique application parameters. Often, a standard catalog valve just isn’t a good fit. Rather than have you design around a catalog valve, Proportion-Air likes to work with each customer to see if modifying our existing technology won’t give you a better answer. See how Proportion-Air can quickly and cost effectively help you engineer a control valve right for your application.

pilot operated regulators

Pilot Operated Regulators

Often called air volume boosters, Proportion-Air manufactures or represents many types of pilot operated regulators to fit your application’s unique parameters. Both piston operated and diaphragm operated volume boosters are offered. Models are available for high pressures, ratio operation (1:1, 1:2, 1:6, and 1:15), steam temperature control, vacuum pressure control, very low pressure control, and for high temperatures. Air piloted regulators are also available in a wide variety of body and elastomer materials for oxygen clean/oxygen compatibility or for corrosive applications.

control valve accessories

Control Valve Accessories

Proportion-Air manufactures and supplies accessory equipment for the operation of your electronic pressure or electronic flow control valve. AC to DC power supplies, analog command signal sources, control valve mounting brackets, pre-wired power cords, ultra-sonic distance sensors, and panel meters to display the pressure or flow readings are available.
