QR4000 SERIES - UHP SINGLE STAGE, PRESSURE REGULATOR

Customer Value Proposition:

 

The QR4000 is a high purity, high pressure non-tied diaphragm regulator. It utilizes a metal-to-metal diaphragm seal which provides enhanced leak integrity.

 

The NPR4000 regulator is for applications involving negative delivery pressures with low pressure gas sources. Typical applications include the delivery of low pressure gases from liquid sources such as WF6, BCL3.

 

Product Features & Benefits:

·       “VeriClean”, Veriflo’s custom low sulfur high purity 316L Stainless Steel™ enhances electropolishing, welding and corrosion resistance.

·       Unique compression member loads the seal to the body without requiring a threaded nozzle or additional seals to atmosphere.

·       Threadless internal nozzle assembly.

·       Metal-to-metal diaphragm to body seal assures high leak integrity.

·       Minimal particle generation and entrapment.

·       Positive upward and downward diaphragm stops.
