The higher flow single stage free diaphragm regulator in the RX family, with five flow capacities from Cv 0.15 to 1.1 and outlet pressures from 0.7 to 10 bar. Inlet ratings of 21, 117, 207 and 240 bar apply depending on the Cv and outlet chosen, because not every combination reaches every rating. Connections extend to 1/2 inch VCR alongside the 1/4 inch options. Assembly, testing and packaging are done in an ISO Class 4 cleanroom, and each regulator carries an individual serial number.

Common questions
- Is the RX 4000 a single stage or a dual stage regulator, and does it matter?
- Single stage, free diaphragm. As the inlet falls the outlet shifts: 0.25 bar for every 100 bar of inlet change on the Cv 0.15 body, rising to 4 bar on the Cv 1.1, so on the larger bodies an emptying cylinder moves the outlet noticeably. Where the process cannot accept that, a second regulator is added downstream. On a steady supply, such as a panel fed from a manifold, the single stage RX 4000 is usually enough, and it is the higher flow body in the RX family.
- How do I pick the Cv for an RX 4000?
- By the flow the point of use needs at the outlet pressure you set. The five sizes are Cv 0.15, 0.25, 0.5, 0.9 and 1.1, with outlet versions of 0.7, 2, 4, 7 and 10 bar and inlet ratings of 21, 117, 207 and 240 bar. Not every combination reaches every rating, so tell us the gas, the inlet pressure, the outlet pressure and the flow and we will confirm the version.
- What connections and body options does the RX 4000 have?
- 1/4 inch or 1/2 inch VCR, male or female, on two, three or four port bodies. The body is AISI 316L to SEMI F20, the seat PCTFE with polyimide optional, and the working temperature minus 20 to plus 65 C. Each regulator is assembled, tested and packaged in an ISO Class 4 cleanroom and carries its own serial number.
