Description
The SEAFLO aerator valve SFVL-01 is an important safety component for piping systems in marine toilets and other water systems installed below the waterline. This anti-siphon valve prevents water from naturally flowing back or siphoning through hoses, which could lead to flooding or contamination of the system.
The internal valve automatically allows air when a vacuum is created in the pipe. This immediately interrupts siphoning without the need for external venting. The housing is made of strong, corrosion-resistant plastic and is designed for long-term use in marine environments.
This model is suitable for hoses with a diameter of 19 mm and can be used in both supply and discharge lines of onboard toilets and other water installations.
