The YeeValve TT9800 Breather Valve, a Pilot-Operated Pressure Vacuum Relief Valve, is designed for use on liquid storage tanks and other containers or systems to prevent damage due to excessive internal pressure or vacuum.

Compared to standard relief valves, the pilot-operated valve offers two primary advantages:

  1. It provides an airtight response to set pressures.
  2. It fully opens when pressures are within 10% below the set threshold. These features allow it to operate very close to the maximum allowable working pressure of the storage tanks. The higher operational pressure reduces evaporation and venting, thereby minimizing product loss and the cost associated with handling emissions.
