Dec 16, 2011 Featuring field-adjustable PID potentiometer, QPV Series controls pressure from vacuum to 150 psig, including differential and absolute ranges. Variable orifice proportional solenoid valve on input pressure side eliminates digital stepping for smooth, ripple-free pressure control. With IP65 construction that is insensitive to vibration or mounting orientation, unit is suited for leak testing at low pressures, air-over-liquid dispensing, and gas chromatography.

Energy Savings Device regulates AODD pump operation.

Proportion-Air, Inc.    McCordsville, IN 46055
Oct 14, 2009 Designed to help conserve energy used by air operated double diaphragm (AODD) pumps, MizAir® uses fuzzy logic to analyze each stroke of pump and learns its unique characteristics. This electro-pneumatic smart device automatically makes internal adjustments to reduce pump's air consumption, consequently reducing energy required to run pump with little to no effect on its throughput, fluid flow, or flow rate.

Closed Loop Regulator is optimized for flexibility.

Proportion-Air, Inc.    McCordsville, IN 46055
Jul 02, 2009 Able to proportionally control pressures up to 150 psig, HVC suits high-volume OEM applications requiring closed-loop control and high forward and relief flow rates. Mounting placement and orientation flexibility is due to shock and vibration resistant technology integrated within 2 x 2 x 4.5 in. IP65 housing. Integral pilot operated regulator ensures equalized operation under flow/static volumes, and internal pressure sensor offers closed loop control that will not change over time.

Pressure Control Valve allows air to move at up to 150 psig.

Proportion-Air, Inc.    McCordsville, IN 46055
Apr 28, 2009 Suited for use with flow meters, QL3 Pressure Control Valve utilizes current driven variable orifice proportional solenoid valves combined with analog PID circuit on high flow volume booster to optimize air movement. PID circuit integrates error out to maximize resolution, and volume booster is designed so there are no stamped gaskets or molded diaphragms or seal parts; all of parts related to normal maintenance are standard o-rings.

Pressure Regulator comes in stainless steel manifold version.

Aug 28, 2008 Combining 303 stainless steel and Viton wetted parts, Electronic Pressure Regulator is suited for wide range of applications such as food processing, pharmaceutical, petrochemical, and semi-conductor, where yellow metals are undesirable. Unit can be calibrated from full vacuum to 1,000 psi.

Pressure Transducers feature stainless steel wetted parts.

Proportion-Air, Inc.    McCordsville, IN 46055
Aug 28, 2008 Intended for use in food processing, pharmaceutical, petrochemical, and other applications requiring 303 stainless steel parts, pressure transducers are available with wide range of pressure ranges with either 4-20 mA or 0-10 V output. Units can be offered with variety of calibrations ranging from -29 in. Hg to 7,000 psig.

Pressure Control Valve features onboard display.

Proportion-Air, Inc.    McCordsville, IN 46055
Aug 28, 2008 Model QB3 is available with onboard digital pressure display with accuracy of .3% FS Offering flow rate of 25 scfm in both forward and exhaust, unit is suited for precise electronically controlled pressure regulation of compressed air and other gasses. Valve comes with command inputs of either 0-10 Vdc or 4-20 mA, and separate 0-10 Vdc pressure-sensor feedback is standard in all units.

Valve controls pressures from full vacuum to 500 psig.

Proportion-Air, Inc.    McCordsville, IN 46055
Oct 16, 2006 With slightly enlarged air piloted regulator section, Model QB3H features Nor-Kote(TM) surface finish for high corrosion resistance. Aluminum bodied valve is suitable for most inert gases in high pressure applications, while brass valve is designed and cleaned to specifications for use with oxygen service. NEMA4/IP65 rated units feature stainless steel pressure transducers.

Control Valve conserves air in diaphragm pump operation.

Proportion-Air, Inc.    McCordsville, IN 46055
Aug 17, 2006 Utilizing microprocessor control air dispensing system, MizAir(TM) produces pulsating effect that allows for reduction of air consumption up to 50% without any loss of fluid flow during operation of Air Operated Diaphragm Pumps. Product consists of high-flow, NO, 2-way, ¾ in. NPT full flow valve and electronic control unit in NEMA4 enclosure. Intelligent device continuously monitors pump speed and operating parameters and makes adjustments to valve timing as needed.
