The RB 1700 & RB 1800 series feature 3/4″, 1″ (RB 1700) and 1″1/2 (RB 1800) sizes. The 3/4″ size is specially designed for high pressure reducing applications, such as LPG first stage pressure reduction, while the 1″ and 1″1/2 sizes are appropriate for Commercial & Industrial applications such as burner and large appliance regulation, where fast response is required. Their balanced valve design provides constant outlet pressure under all inlet pressure conditions.

The RB 1700 & RB 1800 series also include a built-in safety shut-off valve for over-pressure and under-pressure protection, a mistake-proof SSV by-pass and a creep relief valve (on low outlet pressure versions RB 1800 only).
