Weir Type Diaphragm Valve Unlined Flanged PN16

Description
The flanged PN16 weir-type diaphragm valve combines the rugged performance of diaphragm control with the strength and sealing integrity required for larger or higher-pressure pipe networks. The flanged ends conform to PN16 standards, allowing secure bolted installation in industrial, chemical, and process systems. This variation maintains the core advantage of diaphragm isolation no moving metal contact with the fluid while supporting bigger bore sizes and heavier duty service.

Technical Data

• Valve Type: Weir-type diaphragm valve
• Body Material: Cast iron or ductile iron
• Diaphragm Material: EPDM/NBR or compatible elastomer
• Connections: Flanged PN16
• Pressure Rating: Rated PN16 1" to 2", PN10 2½" to 6"
• Temperature Range: 10 °C to +120 °C (depending on diaphragm elastomer)
• Actuation: Manual handwheel; gearbox or pneumatic operator optional

Key Features

• PN16 flanged ends for secure installation in larger pipework
• Diaphragm design eliminates metal-to-metal dynamic contact
• Excellent for throttling and full shut-off duties
• Suitable for a broad range of clean and mildly corrosive fluids

Installation & Application Notes
Match flange drilling and gasket class to system design. Confirm diaphragm elastomer compatibility with the process fluid and temperature. These valves are well suited for water works, bulk chemical handling, wastewater, slurry batching, and systems demanding low contamination and easy maintenance.
