3100 End of Line Conservation Breather Vent

The 3100 end-of-line conservation breather vent is designed for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief is required.

Weight loaded pallets in the vent housing allow the intake of air and the escape of vapours as the tank breathes due to thermal changes and product movement in and out of the tank. The pallets open and close to permit in breathing and out breathing necessary to maintain the tank pressure within permissible limits to avoid damage to the tank

Maintains Accurate Settings: Minimum setting available is ½ oz/in2 for both pressure and vacuum. Maximum setting upwards to 2.5 psig for pressure and 1 psig for vacuum. If higher settings are required see Valve Concepts Series 4000 Spring Loaded Vents or Valve Concepts Series 5000 Pilot Operated Vents. All vents are tested to high standards for both leakage and set point prior to shipment. A certified test certificate is included with each vent verifying the accuracy of both the pressure and vacuum setting and leakage. A leakage rate of less than 1 SCFH at 90% of set point is verified for both pressure and vacuum.

Condensate Drainage: Self-draining housing body and drip rings keep condensate away from seating surfaces, preventing freezing, binding and clogging. Air-Cushioned Seating. Air-cushion seating provides tight sealing to reduce evaporation losses and the release of toxic vapours. The pallets have outer guiding and centre stabilizing stem to provide self-alignment and tight seating.
