40L
Automatic Reseating Temperature and Pressure Relief Valves and Flood Sensor
Series 40L Automatic Reseating Temperature and Pressure Relief Valves now come packaged with SentryPlus Alert® discharge line flood sensors for monitoring unwanted valve discharges once activated. Activating the sensor requires purchase of an additional connectivity kit to read the sensor and signal a building management system.
Series 40L valves provide higher capacity temperature and pressure protection to domestic hot water supply tanks and hot water heaters for various commercial applications. Valves are ASME rated and CSA listed.
