Model 750-86 - Level Control Valve

WW_750-86_Big_GalleryThe Model 750-86 Level Control Valve with Bi-Level Altitude Control is a hydraulically controlled, diaphragm actuated control valve that shuts off at pre-set reservoir high level and fully opens at pre-set low level, as sensed by two 2-Way high sensitivity altitude pilot mounted on the main valve.

Typical Application

Bi-Level Water Towers
The Model 750-80-X senses the static head of the water level in the tank by means of a high sensitivity pilot. To do so accurately, the sensing tube end must be connected to a “still point” at the bottom of the tank. The drainage pipe provides this “still point,” a location not influenced by flow velocity as in filling and outflow pipes.
