Model 3K00

Description:

The Model 3K00 Pressure/Vacuum Vent is designed for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief is required.

Available Sizes

• 2" (DN50)
• 3" (DN80)
• 4" (DN100)
• 6" (DN150)
• 8" (DN200)
• 10" (DN250)
• 12" (DN300)

End Connections

• DIN PN10
• ASME 150 RF

Features

• Maintains Accurate Settings: Standard settings for pressure are +5 mbar to +50 mbar and for vacuum -2,5 to -50 mbar. Other settings are available upon request. All vents are tested to Cashco 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. Seat leakage meets or exceeds international standards (ISO 28300, API 2000).
• Condensate Drainage: Self-draining body and specially designed seat ring keeps 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 vapors. The pallets have outer guiding and center stabilizing stem to provide self alignment and tight seating.

Technique

Weight loaded pallets in the vent housing allow the intake of air and the escape of vapors 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.
