Electro-Pneumatic Proportional Valve - 1

Electro-Pneumatic Proportional Valves Proportional Valve Proportional Valve with Booster STANDARD SPECIFICATIONS Common Specifications: Analog Monitor Signal: Voltage: 0 – 10 volts DC@20 mA maximum. Current: 4 – 20 mA sinking (sourcing optional). Ambient/Media Temperature: 32° to 158°F (0° to 70°C). Body and Dome: Zinc. Command Signal Impedance: Voltage: 4.7 k . Q Current: 100 . Q Voltage/Current: 0 – 10 volts DC/4 – 20 mA. Command Signal Electrical Connector: 6-pin Brad Harrison or 5-pin M12. Fluid Media: Compressed Air. Housing: Aluminum; powder coated. Input Pressure: 29.9 in Hg to 300 psig (760 mm Hg to 20.7 bar). Manifold: Brass. Output Pressure: 0 to 200 psi (0 to 13.8 bar). Seals: Fluorocarbon. Supply Voltage/Current: 15 – 24 volts DC/250 mA (required). Transducer: Silicon, aluminum. Valves: Nickel-plated brass. For Proportional Valve with Booster only: Accuracy: < ± 2.5% F.S. Linearity/Hysteresis: < ± 2.0% F.S. BFSL. Repeatability: < ± 0.6% F.S. For Proportional Valve only: Accuracy: < ± .25% F.S. Linearity/Hysteresis: < ± .2% F.S. BFSL. Repeatability: < ± .2% F.S. GENERAL: The Series RER1 Proportional valve is ROSS CONTROLS’ latest product using closed loop control technology. It incorporates many important standard features. Standard flow rate of the valve is typically one scfm maximum. When used with a volume booster a flow rate in excess of 1,000 scfm can be achieved. Check the items below to see how cost-effective these valves can be in your plant. FEATURES: • • • • • • Fits into very small space Accurate to < ± 2.5% F.S. 0 – 10 volts DC analog monitor output NEMA 4 1P65 rating Accepts analog command signal inputs Proportional valve with regulator: control pressure ranges from vacuum to 300 psig (20.7 bar) • Flow rates can exceed 1,000 scfm • Valve is insensitive to shock, vibration, or mounting position • Easily repairable in the field Note: High-pressure Proportional valve Q175 psi (12 bar) - inlet and exhaust ports reversed from picture shown.
