It is important to us to support our customers during the green transition of the maritime industry.

The function of pressure relief valves

The function of pressure relief valves is to protect a system from overpressure conditions that could cause damage or failure. When pressure within the venting system reaches set point, the valve opens and releases excess pressure to the environment, preventing the system from becoming overpressurized. This helps to ensure the safety and reliability of the system. 

The function of vacuum valves

The vacuum valve function is to enable the release of air or gas as needed to maintain the desired pressure. Vacuum in the venting system is to be avoided wherever possible. Vacuum valves ensure a fast compensation in any vacuum situation, in order to avoid any damage to the cargo, ship or crew.
