DIN Flanged Globe Valve Screwed Bonnet Bronze

Key Features

• Bronze Body Construction: Offers corrosion resistance in compatible water and marine fluid applications. The specified bronze alloy should be matched to the fluid composition, temperature, flow velocity and surrounding piping materials.
• Screwed Bonnet Design: The bonnet connects to the body through a threaded joint, forming the upper pressure-containing assembly. This arrangement allows access to internal components during maintenance in accordance with the manufacturer’s instructions.
• Stem-Driven Closing Mechanism: The stem transfers operating force to the disc, bringing it into contact with the seat to stop flow. Seat condition, closing force and the specified leakage criteria determine shut-off performance.
• Flow Adjustment Capability: Where an appropriate regulating disc is fitted, progressive disc movement allows the flow passage to be adjusted. Continuous throttling requires evaluation of flow capacity, differential pressure and potential erosion or cavitation.
• DIN Flanged Connections: Flanged ends provide detachable connections for installation and replacement. Flange drilling, sealing faces and pressure designations must match the connected piping.
• Maintenance Accessibility: The bonnet assembly provides a route for internal inspection after the valve has been safely isolated, depressurized, drained and cooled.

Applications

• Marine and Shipbuilding: An option for compatible shipboard auxiliary and utility systems requiring bronze construction, subject to applicable classification and installation requirements.
• Freshwater Distribution: Suitable for consideration in freshwater isolation and distribution duties. Drinking-water applications require separate confirmation of material compliance and approvals.
• Cooling Water Systems: Can be considered for compatible cooling circuits where the valve’s flow resistance and pressure–temperature limits meet system requirements.
• Seawater Piping: Suitability depends on the confirmed bronze alloy, internal materials, seawater conditions and compatibility with adjacent components.
• Industrial Utility Systems: Applicable to compatible utility fluids after verifying the complete valve’s material compatibility and operating limits.
• Ship Repair and Replacement: An option where the existing valve’s function, installation length, flange dimensions and operating clearances can be matched.
