Overview of Ductile Iron Ball Valve Flanged PN16 Direct-Mount Brass Ball / Stem / NBR O-rings

Description
This flanged-end ball valve combines a robust ductile iron body with a brass ball and stem assembly, sealed with NBR O-rings to deliver reliable performance in general industrial applications. The direct-mount design supports bolt-on actuation or gearbox mounting, making it ideal where automation may be desired. A full-bore ball offers minimal pressure drop, and PN16 flanged ends provide a standardised connection to the piping system.

Technical Data

• Body Material: Ductile iron (epoxy-coated)
• Ball Material: Brass
• Stem Material: Brass
• Seat / Seal: NBR O-rings
• End Connections: Flanged, PN16 rated
• Pressure Rating: PN16 (~16 bar)
• Operating Temperature Range: 10 °C to +90 °C (typical for NBR seals)
• Mounting: Direct-mount pad for gear or actuator interface

Key Features

• Strong ductile iron body capable of handling moderate pressure and mechanical load
• Brass ball and stem reduce wear and corrosion under typical service conditions
• NBR O-ring sealing offers a reliable seal for water, air, and many fluids
• Flanged PN16 end connections simplify integration into standard industrial pipelines
• Direct-mount pad allows easy upgrade to manual gearbox or automation later

Installation & Application Notes
Ensure flange faces and gasket surfaces are clean and aligned prior to installation. Tighten flange bolts in a star pattern to maintain even compression and prevent distortion. When installing an actuator or gearbox onto the direct-mount pad, confirm that coupling and shaft alignment are accurate to prevent stem binding. This valve is well suited for general service linessuch as chilled water, compressed air or chemical supplywhere moderate pressure and temperature ranges apply. For fluids outside standard compatibility (e.g., high temperature or aggressive chemicals), check that NBR seals remain appropriate.
