The TT7100/8100 Series pressure/vacuum relief valves are essential solutions for managing the pressure dynamics in storage tanks. These valves effectively prevent losses associated with both overpressure and negative pressure, significantly reducing steam loss caused by tank "breathing."

Key Features:

• Size Range: 2" to 12" (DN50-DN300)

  • API7100 Series: Discharge port matches the inlet, allowing easy selection for users.
  • API8100 Series: Larger discharge port enhances exhaust volume.
• Breathing Modes: Supports both discharge and inhalation of atmospheric air.
• Rainproof Cap: Facilitates easy disassembly for inspection and maintenance, with a protective net to prevent debris ingress.
• Customizable Options: Add-ons available such as explosion-proof flame arresters, inhalation bends, jackets, blowing holes, linings, and dehumidification features (please confirm requirements before ordering).
