HVL Series for 3/4" ID Hose Bronze Vented Loop
Material: Bronze
Hose ID: 3/4"
Allows air to enter to break siphon, but does not permit air and odors to escape! Cap is threaded 1/2" NPT to accept a barb fitting if you wish to vent overboard.
Overboard venting is required if HVL series is used in an exhaust system.
HVL Series vented loops assure clog-free anti-siphon protection for sanitation or engine exhaust systems.
The oversized vent valve can easily be removed for inspection or cleaning without tools.
