Keystone™ F791A Solenoid Valve

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

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
