Keystone™ F791A Solenoid Valve
High flow NAMUR-mount solenoid design enabling direct actuator installation for reliable pilot operation.
主要功能
- 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
