Carrier EB51LZ221 Pressure Relief Valve 220 PSI 3/4X3/4 NPT female X male

The Carrier EB51LZ221 Pressure Relief Valve is a safety device that is meant to be used on your Carrier HVAC system. This valve measures 0.9”W x 0.8”D x 3.6”H and, although small in its design, is essential in safeguarding your equipment. In this case, the pressure that is built up beyond a safe limit, normally 220 PSI opens the EB51LZ221 valve to release the pressure. This pressure relief mechanism protects your HVAC system from possible harm that high pressure may bring. The valve has a 3/4” female and male NPT on both ends to allow easy connection to the Carrier equipment.
