This Maestrini siphon break valve is made from brass. It is used to operate anti-siphon loops (41001+) typically on board boats where equipment is installed below the waterline, such as engine intakes, wet exhausts and marine toilet systems.

The valve is fitted with a check ball to prevent siphoning from taking place and a pin to minimize ball rotation.
