Watts Regulators series LFN36 lead free water service VAC uum relief valves are used in water heater/tank applications to automatically allow air to enter into the piping system to prevent VAC uum conditions that could siphon the water from the system and damage water heater/tank equipment. It consists of a lead free brass body construction with NPT male inlet connection, and a protective cap. Series LFN36 has a low profile design, is tested and rated to ANSI Z21.22, and is CSA certified. It is suitable for low pressure steam and water service, and is ideal for use in domestic water heaters and supply tanks, table top heaters, jacketed steam kettles, unit heaters, low pressure steam systems, and steam coil heaters.

• Protective cap for automatic venting of a closed system to atmosphere when a VAC uum is created
• Suitable for low pressure steam and water service
• Permits air to enter and prevent VAC uum conditions that could siphon the water from the system, resulting in collapse of a tank or water heater or equipment burn out
• 302 stainless steel spring
• Polysulfone glass filled float
• Polypropylene cover
• 200 psi maximum working pressure
