Level Control Valve

The Model 750-80-X Level Control Valve is a hydraulically controlled, diaphragm actuated control valve that shuts off at pre-set reservoir high level and fully opens in response to an approximately one meter (three foot) level drop, as sensed by the 3-Way altitude pilot mounted on the main valve.

Features and Benefits

Line pressure driven - Independent operation
Bi-level altitude pilot

  • No float, simple installation
  • On/Off service
  • No cavitation damage
  • Suitable for low quality water
  • Reservoir inherent refreshing

Double chamber design

  • Moderated valve reaction
  • Protected diaphragm

External installation

  • Easy access to valve
  • Easy level setting
  • Less wear and tear

Balanced seal disk - High flow capacity
In-line serviceable - Easy maintenance
Flexible design - Easy addition of features

Typical Applications

The Model 750-80-X senses the static head of the water level in the tank by means of a high nsitivity 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.
