Type R122H First-Stage Regulator
Introduction
The Type R122H is an Underwriters Laboratories listed
regulator designed for Two-Stage LP-Gas systems.
The unit is designed to reduce the tank pressure to an
outlet pressure of 10 psig. The compact size makes it
ideal for small domestic applications and underground
tanks. The outlet pressure setting is nonadjustable
and is factory set at a nominal 10 psig. Screened drip-
lip vents are oriented over the outlet as standard.
Features
