North American Pneumatic Cycle Valve The 1447 Pneumatic Cycle Valve isolates oil, water, or gas in industrial applications including air dryers, ovens, furnaces, autoclaves, food, and sterilization processes. They are high duty cycle on/off angled globe valves that are primarily used on StepFire™ and TwinBed II™ systems. Compressed air opens the valve and a spring returns the valve to the original closed position. The "Y" pattern valve is operated by a linear piston actuator. When the valve is in the normally closed position, the pressure is against the valve seat, not the packing. The shaft seals are self-adjusting and protected by a wiper ring against fouling and damage. This ensures a tight seal even after long periods of operation. The fail-safe actuator is maintenance-free and can be rotated 360 degrees.

The North American 1447 can be ordered with two-position indication switches only. Single position is not available. Specify -LL after the part number. Example: 1447-2-LL. The position indicator consists of two micro-switches with roller arms. Each switch is mounted on a carrier. Separate threaded spindles enables them to be independently adjusted for a maximum stroke of 20 mm. The unit is mounted on a plastic base that can be rotated 360 degrees. The complete assembly fits under a transparent hood which fits on the base plate. Two PG 9 cable glands are supplied for the electrical connections....
