Excess Flow Valves

Brand: GasBreaker
Request Information

If you have questions on the sizing and application for Excess Flow Valves, please submit a “Request for Information” and a CR Wall representative will be glad to help you.


 

The GasBreaker EFV is manufactured in a wide variety of models that can accommodate service line capacities for both residential and commercial applications. 

All GasBreaker EFVs Feature:

Simplicity of Design

  • 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 repressurize 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

 

 

Features

Durable/Maintenance-Free Construction

  • Made of plastic materials proven in use on natural gas systems
  • Require no lubrication and are compatible with all types of pipe materials and configurations – plastic-toplastic, steel-to-plastic, and steel-to-steel
  • Constructed of maintenance-free materials that surpass stringent gas utility requirements
