drip-lip vent is oriented downward and the second-stage
vent is oriented over the outlet as standard.

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.
