Info
Designed for use as a First-Stage regulator for
domestic applications, the Type R122H’s size makes it perfect for tight
installations. Stainless steel internal parts and corrosion resistant
coatings provide a recommended replacement life of 20 years. Its
non-adjustable setpoint makes the unit virtually tamper proof. Inlet
and outlet gauge taps allow easy system testing. Large inlet and
outlet wrench fl ats provide for easy installation, even in underground
tanks. The outlet pressure setpoint remains at a nominal factory
setting of 10 psig / 0,69 bar. The designs superior relief performance
exceeds UL requirements and provides double failure overpressure
protection when used with R600 Series Second-Stage regulator.
The unit’s Fluorocarbon (FKM) valve disc provides better lockup
performance and durability in contaminated gas. The vent is with
3/8-inch NPT for easy installation of vent piping. A large fabricreinforced
diaphragm provides accurate regulation. The large orifi ce
assists in minimizing freeze problems.
