Why Storagetech Pressure Vacuum Valve?

Liquids are mostly carried or kept in the closed vessels or tanks, some reasons such as evaporation or weather conditions may cause the fluctuation at the pressure level in the vessels or tanks. Vessels or tanks that filled with liquids must have an opening points through which the accumulated pressure might be released and vacuum in the tank or vessel compensated. For that, Pressure Vacuum Valves are provided with weight-loaded or spring-loaded valve discs. In the case of overpressure in the tank, the overpressure valve disc guided in the housing is lifted and releases the volume flow into the atmosphere. When there is a vacuum in the tank, the overpressure of the atmosphere lifts the vacuum disc and the tank is vented.

Pressure Vacuum Valve is fitted on a tank roof flange or pipe that connects to the vapor space of a storage tank. In the closed position the weight-loaded pallet and diaphragm assembly is held tightly against a seal to prevent the loss of vapor to atmosphere. As the internal pressure in the tank reduces, due to emptying, the balance between the tank pressure and the external atmospheric pressure changes, and when the set pressure of the unit is reached, the diaphragm will open to admit air and rebalance the internal pressure.

StorageTech Pressure Vacuum Valve provides protection to bulk storage tanks and vessels from over and under pressurization. The valves are mounted on the tank roof flange or a vent pipe from the vapor space. System is especially preferred for transferring vapor content to collection system or condensation units, even prevent certain fire hazards.

StorageTech pressure vacuum valves carry many benefits with its features. It is easy to install, does not require any special tools or experience. It transfers vapor content to collection system or condensation unit. It is protected for certain fire hazard, has light weight construction and any grade materials are available.

  • Other key features are as follows:
  • Has stainless steel pallets.
  • Special designs can be achievable upon request to meet individual specifications.
  • Eliminate the intake of air content (if needed) and the escape of vapors,
  • Internal materials are resistant to winter conditions.
  • Vacuum and relief cases can be managed effectively as per the set requirements of bulk storage tank.
  • Super Duo technology provides extra curves and perfect seating with zero leakage.
  • Set values can be arranged as per the site conditions, no need supervising.
  • Design, manufacturing and test according to EN ISO 80079-36.
  • PTFE, XYLAN, Rubber lining,etc. coating options are available.
  • ANSI, DIN, JIS, APl,etc. any special end connections are available
  • Breathing requirements are fulfilled according to APl 2000 7th Edition.
  • Diaphragm is manufactured from PTFE material to prevent possibility of ice formation and sticky residues hindering the valve from opening, while the pallet assembly moves freely on guide posts.
