Rego® Low Pressure Second Stage Regulator (LV5503B8)

he RegO LV5503B8 Regulator is 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, regulator is designed to not pass more than 2 PSIG with the seat disc removed
