Pressure equalisation valves adjust for any pressure difference and prevent damage to stored or transported products due to internal or external overpressures.

Description of pressure equalisation valves

Atmospheric pressure differences between the containers and the external atmosphere are brought about by air transports and temperature fluctuations on the ground. Pressure equalisation valves are used to prevent damage to the transported goods or storage containers due to internal or external overpressure. Pressure equalisation valves are set to any desired pressure differences and are available in a variety of designs. They are offered as 1- and 2-way valves, as well as with or without manual discharge. The pressure equalisation valves comply with the requirements of the International Air Transport Association (IATA) and the Society of Automotive Engineers (SAE).

Applications of equalisation valves

The main applications of pressure compensating valves are:

Export of products
Protection of goods
Military applications
Aviation industry

Specifications of equalisation valves

Below is a table specifying the different types of pressure compensation valves based on their flow rates, that is, the amount of steam or gas they let through.

Further pressure equalisation elements specifications

Below we show you the specifications of the open pressure compensation elements for protection against dust and splashes which, however, unlike valves, allow the passage of water vapor.
