A207

Series A207 ATEX Normally Open Servo-Assisted Solenoid Valves Ultravalve supplies the Series A207 2 way normally open servo-assisted diaphragm solenoid valve for automated on/off flow control in hazardous-area industrial fluid systems. Equipped with an ATEX certified explosion-proof coil and brass valve body, the A207 is designed for applications requiring normally open operation and reliable diaphragm-assisted performance. Servo-Assisted Flow Management for High Capacity Systems Ready for rapid dispatch from our UK warehouse, subject to configuration and current availability, the A207 supports system integrators, maintenance teams and facility engineers requiring replacement valves for hazardous area pipeline systems. The servo-assisted diaphragm design provides high capacity flow control while requiring a defined minimum differential pressure for correct operation. Full Hazardous Area Certification: Features an ATEX certified explosion-proof coil for gas and dust hazardous areas: ATEX II 2GD Ex d IIC T6/T5/T4 Gb IP66 and Ex tb IIIC T85°C/T100°C/T135°C Db IP66. Normally Open Operation: The A207 is a 2 way normally open solenoid valve, allowing flow in its de-energised state and closing when energised, subject to correct specification and installation. Servo-Assisted Control: The diaphragm design supports higher flow capacity than direct-acting alternatives, with standard versions requiring a minimum differential pressure of 0.15 bar and reinforced diaphragm versions requiring 0.5 bar. Defined Pressure Operation: The operating table lists maximum differential pressures from 15 bar down to 10 bar, depending on valve size and configuration. The published maximum allowable pressure value should be confirmed before being used in application-critical specifications. Robust Brass Construction: Manufactured with a brass body and available with FPM or NBR seal materials, with seal selection dependent on valve code and media compatibility. Continuous Electrical Duty: Rated for ED100% continuous service, supporting continuous coil energisation in suitable industrial applications. Flexible Installation: Available in the operating table with G1/4 to G2 ISO 228 threaded connections, with additional dimension data shown for larger sizes requiring confirmation before specification. Electrical Connection: Supplied with a 1/2" NPT electrical connection, with M20x1.5 available on request. Slow-Closing Option: Available with slow-closing diaphragm versions to help reduce water hammer in suitable pipeline systems. With over 30 years’ experience and an ISO 9001:2015 certified quality management system, Ultravalve provides dependable valve solutions for UK industry.
