HPR 540 Series is cost effective product equivalent to Concoa 432 series, Tescom 44-3400 series, Go Regulator CYL-20 series, Swagelok KCY series.

The HPR 540 series is a stainless steel two stage pressure regulator recommended for use with high purity corrosive gases requiring precise, contaminant free pressure control. The two stage design yields a delivery pressure change of less that 0.05% with varying inlet pressure which minimizes the supply pressure effect caused by decaying inlet pressure. Internal surface finish of body is better than 1.6µm which allows easier cleaning and lesser particle contamination. Stainless steel bonnet prevent atmospheric corrosion and maintain appearance.
