OCV 3331

One-Way Altitude Valve

OCV 3331, a one-way altitude valve, controls the level in the tank without the use of floats or probes in the tank itself. It shall be a one-way flow (single-acting) type, designed to open fully to fill the tank and close completely when the predetermined high level is reached. Sensing of the altitude pilot shall be by means of a field-installed sense line between the pilot and the base of the tank. The altitude valve shall be equipped with a visual indicator assembly.

This valve is applicable anywhere it is necessary to automatically maintain the water level in elevated storage tanks or reservoirs. Some examples include: municipal water, rural water, industrial plants.
