CYL-20 Series Pressure Regulators

Corrosion-resistant Two-stage Pressure Reducing Regulator

Precision pressure control is now possible with our advanced design of two stage pressure reducing regulators. Offering the utmost in corrosion resistance and safety, the CYL-20 Series is constructed from 316L stainless steel.

The two stage design has less than 0.01% change in outlet pressure with varying inlet pressure and is suitable for use in all applications where performance, cleanliness and corrosion resistance are of paramount concerns. Stainless steel caps and adjusting screws

prevent atmospheric corrosion and maintain appearance. The internal body surface finish is less than 25 Ra as standard. This, coupled with electropolishing, allows easier cleaning and potentially less particle contamination in the flow stream.

The CYL-20 Series pressure reducing regulator comes equipped with 2″ diameter 316 stainless steel gauges and a stainless steel CGA fitting.
