Model 750-80-X

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

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
