Gas Pressure Regulator
View system integration details
This page explains how Poppet/Valve is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A valve mechanism that uses a poppet (a disk or cone) to open and close a port, controlling gas flow in a pressure regulator.
Technical details and manufacturing context for Poppet/Valve
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Nominal Diameter | 15–50 mm | Common sizes for pressure regulator valves |
| Flow Coefficient (Cv) | 0.5–2.5 US gal/min | Higher Cv for larger sizes |

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The poppet/valve is the primary flow control element. It moves in response to pressure changes to modulate gas flow from the high-pressure inlet to the regulated low-pressure outlet, maintaining a stable downstream pressure.
The poppet/valve is typically made of stainless steel or brass, with an elastomeric seat. The seat material hardness is usually 80–95 Shore A, balancing sealing and wear.
Check the leakage rate (0.01–0.1% of rated flow) and cycle life (100,000–500,000 cycles) against your requirements. Always verify model-specific values and standards with the legal manufacturer or supplier.
