Application : Designed to reduce first stage pressure of 5 to 20 PSIG down to burner pressure, normally 11" w.c. Ideal for larger commercial and industrial applications, multiple cylinder installations and large domestic systems.
Features :

• Incorporates integral relief valve.
• With 15 PSIG inlet pressure, the regulator is designed to not pass more than 2 PSIG with the seat disc removed.
• Replaceable valve orifice and valve seat disc.
• Straight line valve closure saves wear on seat disc and
• Built-in pressure tap has plugged ^1/4 " F.NPT Plug can be removed with a ^3/16 ’’ hex alien wrench.
