This page explains how Diaphragm 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 that uses a flexible diaphragm to control fluid flow by isolating the valve body from the operating mechanism.
Technical details and manufacturing context for Diaphragm Valve

Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 16 bar (standard), up to 25 bar (high-pressure designs) |
| flow rate: | Cv values typically 0.1 to 50 (depends on valve size) |
| temperature: | -20°C to 150°C (varies with diaphragm material) |
| slurry concentration: | Suitable for slurries up to 40% solids by weight (depends on particle size and abrasiveness) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

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 typical operating pressure range is 1.0 to 1.6 MPa. Always confirm the exact range for your specific model with the manufacturer.
Common diaphragm materials include EPDM rubber, nitrile rubber, and PTFE. The choice depends on the application; for example, PTFE offers chemical resistance, while EPDM is suitable for steam. Verify material compatibility with your process.
In pulse-jet systems, a solenoid or pilot valve controls the diaphragm. When actuated, the diaphragm flexes to open the port, allowing a rapid release of compressed air. Quick closing is achieved by de-energizing the pilot, which conserves air.
Standards referenced include ISO 6708 for nominal diameter, ISO 5208 for leakage, and flow, IEC 60529 for ingress protection and control signals, ASTM A351 for body material, and ASTM D1418 for diaphragm material. These are references for verification, not certifications.
