Marioff HI-FOG SBA40-A3P-S38/30-10M Section Ball Valve | 0-3600 PSI

HI-FOG SBA40-A3P-S38/30-10M Water Mist Fire Protect Section Ball Valve 0-3600PSI

The Marioff HI-FOG SBA40-A3P-S38/30-10M (Stock Code: D06160) is a precise heavy duty section ball valve suitable for use in high pressure water mist fire protection systems. This valve is installed contextually in wet-pipe or dry-pipe networks and divides the overall maritime or industrial fire suppression networks into separate zones.

Under normal standby situations this section valve is in its regularly open condition. When the system is activated (either by sprinkler heat rupture or by manual activation), water rushes through the valve and the flow change is detected by an integral differential pressure switch (or flow monitor). The integrated switch instantly communicates back to the fire control panel with a 24VDC electrical signal indicating the particular fire zone that has been activated. This unit has an integrated test port to support local loop testing and a manual shut-off handle to isolate the device during maintenance.

Technical Specifications: SBA40-A3P-S38/30-10M

What are its features?

1. Asymmetrical Connection Sizing: Built with a 38.0 mm outer diameter (O.D.) inlet connection and a 30.0 mm O.D. outlet connection using standard DIN 2353 cutting ring fittings for leak-proof sealing under extreme vibrations.
2. Integrated Zone Identification: Factory placed 24VDC differential pressure switch provides instant notification to the centralized maritime fire safety control board when the sprinkler discharges.
3. Manual Override & Isolation: A physical 90 degree operating sector handle provides manual system isolation for field maintenance, repairs or zone changes.
4. In-Line Test Port: Integral test valve connection allows personnel to safely connect a test hose and perform diagnostic tests on the system without causing downstream water to discharge.

Systems & Equipment Compatibility

Primary System: Marioff HI-FOG High-Pressure Water Mist Fire Extinguishing Systems (Wet Pipe, Deluge, and Pre-Action Configurations).

Compatible Machinery & Spares:

Applications

1. Commercial Vessels: Bulk carriers, Ro-Ro ships, container vessels, and luxury cruise liners.
2. Offshore Units: Fixed drilling rigs, FPSOs, and semi-submersibles.
3. Machinery Spaces: Protection zones encompassing propulsion machinery, auxiliary diesel generators, and purifier rooms.
4. Accommodation Areas: Public spaces, passenger corridors, and galley protection zones.

Maintenance Guiance from NDMarineTech:

• Preventive Exercise: High-pressure marine water mist lines can accumulate localized mineral scaling if the system water is not periodically flushed. Cycle the manual 90° handle once every quarter during routine safety inspections to clear any micro-sediments on the ball seats.
• Electrical Testing Safely: Use the dedicated 1/4″ test port with a test hose (D23050) to route discharge water to a drain bucket. This triggers the differential pressure switch and tests the control board connection without flooding your dry-pipe zones or machinery spaces with high-pressure mist.
• Switch Replacement: If the 24VDC electrical block fails, the pressure differential switch assembly can be unscrewed and replaced without draining down the whole pipe network, provided the manual valve is completely isolated.
