Keystone-F791A

Keystone™ F791A Solenoid Valve

Product Description

A robust, high flow general purpose Namur mount pilot operated solenoid valve for direct mounting to Keystone Figure 89 pneumatic actuators.

Charakterystyka

  • Compact design with standardized, market-proven, NAMUR mounting interface, which reduces installation expense and complexity whilst increasing actuator
  • The black anodized aluminum body of the F791A solenoid valve is supplied with stainless steel fasteners as standard, providing excellent resistance to corrosion
  • Suitable for use with both double and single-acting pneumatic actuators
  • 5/2 or 3/2 way function is selectable via interchangeable port configuration plate
  • Instrument air return (closed loop) is an integral capability of the 3/2 port configuration plate, allowing clean, dry instrument air to be directed to the pneumatic actuator’s springs during the actuator’s spring stroke, thereby protecting the actuator from a contaminated atmosphere
  • High flow capacity of 1100 L/min (1/4” ports) and up to 3000 L/min (1/2” ports) ensures that the F791A solenoid is suitable for most actuators and provides excellent response times
  • Bi-stable (turn and lock) manual override included as standard
  • Ingress protection rating to IP65 (Nema 4,4X)
  • Available with either a single coil (solenoid/spring) or dual coil (solenoid/solenoid) configuration
