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)
The PC30 has exceptional maximum flow, 300LPM at 5.8 watts, and in a compact, 1/8 PIPE, 2-port, valve body. The smaller PC10 valve is a 10-32 threaded, 2-port proportional valve capable of 0-65 LPM flow at 5.8 watt maximum power consumption. The miniature PC3 rounds out the offering at 24 LPM flow at 2.3 maximum power consumption. All are available as inline or manifold mount configurations, with control voltage options of 0-10V or 0-20V, and option picks for maximum pressure ratings and orifice sizes to best suit your application and flow requirements.
All ProControl Proportional Valves are ideal for many types of compressible media including vacuum. With their selectable or dynamic control of media flow, they can be applied to a multitude of market segments such as medical and analytical, testing and instrumentation, as well as factory and process automation. All of the products in the ProControl series are RoHS and REACH compliant.
Now six valves strong of 3-port and 4-port types in three sizes, Humphrey Balanced Valves offer exceptional versatility.
The Balanced Solenoid Valve Series is an universal balanced design valve, offering several benefits:
MULTI-PURPOSE. The Series is versatile with its many functions: Normally Closed or Normally Open; 2- or 3-way; Diverter or Selector; pressure range of vacuum to 125 PSIG.
MULTI-MEDIA. The Series’ balanced poppet design performs whether the media is air or inert gases, clean, dry, lubricated, or contains some airline impurities.
RELIABLE SHIFT, TIGHT SEAL. Internal forces generated by the pressurized media are neutralized. The shifting forces of the coil and return spring are optimized and need only seal the poppet to our tight leakage specifications.
HIGH FLOW CAPACITY. Internal flow path management has been maximized. Coupled with the balanced design and an optimized solenoid magnetic circuit, significantly greater flow, within a reduced overall size, has been achieved.
EASE of USE. All electric and pneumatic connections are on opposing surfaces, minimizing total space occupied, and simplifying mounting and connections during installation.
