Burst Control & Pressure Reducing Valve Model 792-U

The Model 792-U Burst Control & Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve with two independent functions.
When flow is below setting, it reduces higher upstream pressure to lower pre-set downstream pressure, regardless of varying demand or upstream pressure.
Upon sensing flow in excess of setting, it shuts off drip tight and locks (until it is manually reset).
  • Line pressure driven – Independent operation.
  • Hydraulic flow sensor (upstream installation)

-No moving parts

-No electronic components

-No need for flow straighten

  • Sensitive hydraulic pilot – Tight setting window.
  • In line serviceable – Easy maintenance.
  • Double chamber design

-Moderated valve reaction

-Protected diaphragm

  • “Y” or angle, wide body – Minimized pressure loss.
  • Obstacle free, full bore – Uncompromising reliability.
  • Stainless Steel raised seat – Cavitation damage resistant.
  • Semi-straight flow – Non-turbulent flow.
  • V-Port Throttling Plug – Low flow stability.

Typical Applications

Burst Control Valves in a Network
Every water system is vulnerable to bursts, whether due to system problems or external mechanical damage. This illustration shows a reservoir feeding a downhill line with lower elevation consumers. Each Model 792-U protects the lower elevation consumers. It reduces their supply pressure and, in case of burst, “closes & locks,” preventing flooding. The Model 790-M, installed at the reservoir outlet, also protects against reservoir emptying.
