Proportional Valves

The Humphrey ProControl Proportional Valves provide outstanding performance, versatility and value. The inert construction makes this an ideal choice for many types of mulit-media use. The patented frictionless flat-spring armature design results in long, trouble-free and excellent flow characteristics.

Built within a simple, compact valve body is a frictionless design that doesn’t use any sliding parts that will wear out, create variability and ultimately fail over time. This design provides applications with excellent resolution to overcome sticktion and inertia, ultimately achieving superior performance with a high end-gain and faster responsiveness.

ProControl Proportional Valves precisely control air or gas flow across a broad range of applications by using DC current, open- or closed-loop control, or even PWM (Pulse Width Modulation). The unique Humphrey design responds accurately and consistently to any adjustment of current with low hysteresis results and improved control in either direction of flow.

ProControl Proportional Valves are a compact flexible solution for controlling air, vacuum, and inert gases, but also many reagents and corrosive fluids. The valve armature and body are plated to process corrosive media. All wetted surfaces are inert materials with tight sealing characteristics. Stainless steel wetted materials are available for water and corrosive liquids.

PC3 ProControl Miniature Proportional Valve

• The PC3 miniature proportional valve is ideal for precise control up to 24 litres per minute. The PC3 is a compact, flexible solution for controlling air, vacuum, and some gases.

PC10 Pro Control Small Proportional Valve

• The PC10 small proportional valve is ideal for precise control up to 24 litres per minute. The PC10 is a compact, flexible solution for controlling air, vacuum, and some gases. 

PC30 ProControl Large Proportional Valve

• The PC30 large proportional valve is ideal for precise control up to 300 litres per minute. The PC30 is a compact, flexible solution for controlling air, vacuum, and some gases. 

Regulator Series

Expanding the ProControl family to go a step beyond single valves, Humphrey adds the ProControl pressure regulator series of products. These electronic pressure regulators provide outstanding performance, versatility and value. Designed for low volume flow rates (PCRL) or high volume flow rates (PCRH), ProControl regulators precisely sustain outlet pressure, even during dynamic changes in downstream flow rates.

ProControl Series Regulators provide closed-loop proportional pressure control by incorporating a unique, dual proportional valve design. This achieves superior pressure regulation control, including:

• Very quiet operation. Ideal for any work environment, particularly medical and laboratory applications.
• Long service life compared to competitive models using ON/OFF valves for supply and/or venting control.
• Greater responsiveness and stability at dynamic inlet and outlet pressure applications.

Typical applications include: 

• Direct control of pressurized air and inert gases (consult factory for special gases and liquids)
• Operation of small bore cylinders
• Medical / analytical applications
• Leak testing
• Packaging

Features:

• Two frictionless proportional valves control both fill and venting functions.
• Two sizes: Low flow and high flow types.
• Quiet operation, particularly at low pressure settings.
• Relieving regulator type is standard (plug vent port for non-relieving)
• Frictionless design results in multi-million cycle life.
• Made in the USA.
• RoHS and REACH compliant.
