The Watts 374A Series iron pressure relief valve is engineered for use in hot water space heating boiler applications, providing essential protection against excessive pressure. This robust valve is designed to safeguard your system by maintaining pressure within safe limits, ensuring operational reliability and safety. Equipped with a 3/4 inch NPTF female inlet and outlet, the 374A Series offers a pressure relief setpoint of 30 psi, suitable for managing high-pressure conditions effectively. The valve features a durable iron body paired with a forged bronze inlet, ensuring longevity and resistance to harsh conditions. Its non-metallic disc-to-metal seating provides a reliable seal to prevent leaks, while the integrated test lever allows for easy maintenance and functionality checks. For enhanced monitoring, the valve includes a nonrestrictive discharge drain line flood sensor with SentryPlus Alert® technology. This feature enables detection of excessive water discharges, alerting users to potential issues. Note that activation of this sensor requires a separate activation kit, which can be connected to existing building management systems for comprehensive monitoring. Built to meet stringent industry standards, the Watts 374A Series valve is ideal for demanding environments, combining high-quality materials with advanced technology to ensure peak performance and durability.
