Excess Flow Valve Model S11 2" IPS Schedule 40 Thread x Thread 14" LONG, with Series 700 Valve
  • Work with the flow of natural gas as the sensing source
  • Activate when a line rupture causes an excess flow condition
  • Automatically reset and resume normal operation after repairs are made using a slight gas bypass to re-pressurize the line
  • Non-bypass models are also available. These models are reopened by correcting the excess flow condition and manually applying back pressure to the line and valve.
  • Install in minutes with standard tools
  • Operate within your normal service line sizing requirements to avoid tripping by snap-acting loads
  • Higher capacity EFVs can accommodate future increases in gas loads.
  • Maintain stability under turbulent flow conditions by using a unique, dynamically balanced float
  • Available for virtually all pressures and service line capabilities
  • In-line installation makes them tamper-proof
  • Can be fabricated with fitting and piping materials from most manufacturers
  • UL Listed 4DU5 for use on propane service line applications
