CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The typical input signal pressure range is 0.02–0.1 MPa (approximately 3-15 psi). This low-pressure control signal is amplified to a higher output pressure to actuate final control elements.
Common materials include stainless steel, aluminum alloy (often anodized for corrosion resistance), Buna-N rubber for seals, and brass for certain components. These materials are selected for durability and compatibility with pneumatic systems.
Always verify the specific model's ratings with the manufacturer.
The input signal pressure acts on a diaphragm or bellows, creating a force that is balanced against a spring or opposing pressure. This mechanical movement controls a pilot valve that regulates supply air flow, resulting in an output pressure proportional to the input signal.
