Features

• 20-Year Recommended Replacement Life –

The Type R632A is designed using rugged time proven design concepts with enhancements to the corrosion resistance and durability of materials, both internally and externally. With proper installation and periodic inspection and maintenance the Type R632A design has a 20- Year Recommended Replacement Life. In some environmental conditions earlier replacement may be required.

• Improved Regulations – Fisher®’s large molded fabric reinforced diaphragm and spring assisted vent stabilizer deliver accurate, stable regulation.

• Superior Overpressure Protection – The combination of a high capacity relief valve and large vent provide overpressure protection which exceeds UL standards.

• Corrosion-Resistant – Added corrosion resistance with an internal and external coating process for all castings prior to painting, stainless steel relief valve spring and retainer and a non-corrosive relief valve seat.

• Positive Drainage – When installed properly with the spring case pointed down the Fisher Positive Drainage design allows any moisture formed in the spring case to drain out eliminating the problems with corrosion and freezing of the water in the spring case.
