Model 66TS Tank Safety Valve

Model 66TS Tank Safety Valve

The Model 66TS Tank Safety Valve is designed to automatically isolate a fuel storage tank from its loading terminal or product transfer point. Hydraulically linked to the delivery pump, the valve is open only when the pump runs and is effectively producing pressure. The valve will automatically close when the pump is off, fails to produce pressure, or in the event of a line rupture.

  • Thermal relief of excess downstream pressure
  • Provides anti-siphon protection
  • Capable of manual operation
  • Can be maintained without removal from the line
