Diaphragm Valve MV 309

Product catalog summary
Overview: The Diaphragm Valve MV 309 is a compact, pneumatically operated valve designed for chemical and industrial plants. It features a visual position indicator and standard installation length with air connections according to NAMUR standards.
Specifications:
  • Nominal Pressure: PN 6 (H2O, 20°C)
  • Size: DN 15 - DN 32
  • Valve Body Materials: PVC-U, PP, PVDF
  • Bonnet Material: PP, glass fibre reinforced
  • Diaphragm Materials: EPDM, FPM, PTFE (with EPDM diaphragm and PTFE coating)
  • Sealing Materials: FPM, EPDM
  • Actuation: Pneumatic lift actuator
  • Control Functions: NC (normally closed), NO (normally open), DA (double acting)
  • Control Pressure: NC, NO: max. 6 bar; DA: max. 4 bar
  • Connection Types: Various union and spigot ends for solvent and fusion welding according to DIN ISO standards
  • Mounting Position: Flexible, preferably with bonnet at the top
  • Color: Bonnet - orange (RAL 2004); Valve body - grey (PVC-U RAL 7011, PP RAL 7032), opaque yellowish-white (PVDF)
Applications: Suitable for shut-off and control purposes in technical processing plants.
Testing and Standards: Complies with DIN EN ISO 16138, ISO 9393, and DIN EN 12266 standards, with leakage rate A tested.
Pressure/Temperature Diagram: The diagram provides operating pressure and temperature limits for nominal pressures, assuming a 25-year operating life for harmless media. For other media, refer to the ASV resistance guide.
Maintenance: Regularly check the tightening torque of body screws, especially with diaphragm setting and temperature fluctuations.
Actuator Variants: Available in NC, NO, and DA configurations with body materials in PVC-U, PP, and PVDF, each with specific diaphragm and sealing options.
Dimensions: Detailed dimensions are provided for various sizes and materials, ensuring compatibility with installation requirements.
Parts List: Includes valve body, diaphragm, pressure piece, actuator upper part, washer, hexagon bolt, union nut, union end, and O-ring.
