Advanced Valve Temp & Relief Fi 20mm 400Kpa

Product Overview
The Advanced Valve Temperature and Relief FI 20 mm 400 kPa is a safety relief valve designed for use in domestic and light commercial hot water systems. It combines protection against excessive temperature and excessive pressure within a single unit. When either the set temperature or the set pressure limit is exceeded, the valve automatically opens to release water, helping protect the water heater and connected plumbing from unsafe conditions.
