Diaphragm valve WW-750-86

hydraulically-operatedfloatpilot

The 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. PRODUCT FEATURES & 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 PRODUCT APPLICATIONS 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.
