Description
Xylem-Bell & Gossett 110081 1.5 Inch Relief Valve 45,00,000 BTU/H 45 protects hydronic and heating circuits by releasing excess pressure when system levels exceed preset limits within HVAC systems. An internal spring-loaded mechanism responds to rising pressure by lifting the sealing element, allowing controlled discharge to maintain safe operating conditions. Once pressure returns to normal range, the valve reseats automatically to restore closed flow. The body construction is designed to withstand repeated pressure cycles while maintaining stable sealing performance. It is used in compatible boiler and hot water systems where pressure safety control and system protection are required during continuous operation.
