Featuring rugged construction of durable stainless steel, O'Keefe Controls Co. Pneumatic Float Valves are long-lasting and suitable for use in a wide variety of liquids. Their non-electrical operation makes them especially appealing in industrial applications which carry an explosion hazard. They are available in either side- or top-mounting configurations for closed or vented vessels.

Unique Design Allows Lower Cost of Operation

In the O’Keefe Controls Co. Pneumatic Float Valve, the level sensor and pneumatic output valve are separated by the solid wall of the unit's pressure vessel. On the wet side, liquid level is sensed via a float on one end of an arm and a ceramic-coated magnet on the other.

The float rises or falls as the liquid level changes, causing the magnet on the other end of the pivoted arm to move, triggering a magnetically actuated sensor on the outside of the solid metal housing. The movement shifts a 3-way air valve, which enters an actuated state only when the sensor is triggered, thus conserving energy costs on compressed air flowing through the sensor.
