Directional Control Air Valves & Accessories

PROPORTIONAL CONTROL VALVESPV1 PROPORTIONAL VALVEDesigned for industrial applications, the PV 1 deliversprecise proportional control of pneumatic output byreading analog or digital input command signalsgenerated by a programable controller or other remotepower device. Response is instantaneous, precise andrepeatable, relative to input command voltage.PV1 is activated by connection to a 15-24 VDC powersupply. You can the use either analog or digital inputsignals to direct the PV1 to produce a proportionalpneumatic output. This versatility in the module allowsthe use of a variety of controllers and other powerdevices for input signals.PV1 contains two external feedback features. The firstis a 0-10 VDC linear output from a self-containedpressure sensor that monitors pressure at the outputport. The second, a TTL (transistor-to-transistor logic)output, informs you that the PV1 has achieved thedesired command pressure. Also provided is anindicator light on the unit visually signaling thatcommand pressure has been achieved.GENERAL ENGINEERING DATA• Media: Air or neutral gases.• Recommended Filtration: 40 Micron.• Lubrication: Can be used in non-lubedsystems or with standard lubricated lines.• Versatility: Can be mounted to any standardair pilot-operated regulator or the specificallydesignedAlkon pilot operated operated regulator.1/4 NPT male thread standard.• Modular Construction: Factory adjustable andrepairable.ELECTRICAL CONNECTION• Alkon #39A01133 (Analog)• Alkon #39A01134 (Digital)or equivalentsSee page 80 for Connector PinoutInformation.PERFORMANCE SPECIFICATIONSPneumatic Min.
