Cylinder & Two Stage Regulators

Go Regulators


Precision pressure control is now possible with the CYL-20 Series regulator. This two-stage regulator, constructed of 316L stainless steel and PTFE, has less than 0.01 percent outlet pressure change with varying inlet pressures and is designed for use in gas calibration systems and semiconductor materials processing.

With materials of only 316L stainless steel, PTFE and Tefzel®, this regulator is suitable for service in corrosive streams as well as non-corrosive streams with potential surface absorption problems. This regulator accepts inlet pressures up to 6000 psig and has bubble-tight shutoff . Operating temperature ranges may vary from -40° C up to +260° C and outlet pressure ranges of 0–10 psig up to 0–500 psig are easily adjustable by a fl uted knob.
