Model 118-5 Surge Anticipation Valve-Electronic Type

Model 118-5 Surge Anticipation Valve-Electronic Type

The Model 118-5 operates as a pressure relief valve by opening at a pressure above its set point. In addition, it provides extra protection against surges associated with power failure or other pump failure by opening in “anticipation” of the high pressure wave to follow. By being already open when the high pressure wave hits, any potential surge is harmlessly bypassed to atmosphere. Typical examples include pump systems, municipal distribution systems and irrigation systems.

 

Model Features

  • Surge Commander IV control panel provides valve control interface
    -12 VDC continuously charged battery backup
    -Multiple control features
    -Start up time delay – keeps valve closed during pump start to allow for pump check valves to open fully
    -Shutdown time delay – takes valve off line after pump shutdown
    -Surge time delay – determines how long valve stays open during down surge and/or power failure
  • Two selectable operating modes
    -Mode A: Opens on power failure accompanied by a low pressure
    -Mode B: Opens on either power failure or low pressure
    -Mode A or B: Valve remains open an adjustable preset time then slowly closes
  • Opens on high pressure – Closes slowly when pressure returns to normal
  • Operates over a wide flow range
  • Quick opening and adjustable closing speed
  • Can be maintained without removal from the line
