LOW PRESSURE SECOND STAGE REGULATORS
• Replaceable valve orifice & seat disc • Built in 1/8” pressure tap
• Straight line valve closure reduces wear on seat disc
Designed to reduce fi rst stage pressure of 5 to 20 PSIG down to burner pressure, normally 11” W.C. Ideal for medium commercial installations, multiple cylinder installations & normal domestic loads. Features integral relief valves, large vent with 3/4” FNPT for vent piping & a unique bonnet vent profi le to minimize vent freeze. Select brown fi nish.
