Overview
The Brass Ball Valve is designed for quick and reliable on-off isolation in water supply, plumbing, HVAC, irrigation, compressed air, and general utility systems.
The valve uses a quarter-turn ball with a through bore to control the medium. When fully open, the bore aligns with the pipeline and provides a straight flow passage with low pressure loss. The brass body, compact threaded construction, and lever operation make it suitable for frequent and convenient shut-off service.
Product Advantages
● Fast 90-degree opening and closing
● Compact and lightweight construction
● Reliable shut-off performance
● Low operating torque
● Low pressure loss when fully open
● Simple installation and maintenance
● Suitable for frequent isolation service
Technical Specifications
Size Range
● NPS 1/4\”–4\” (DN8–DN100)
Pressure Rating
● PN10 / PN16 for EN 13828 building water-supply configurations
The rated pressure decreases as operating temperature increases. The pressure–temperature rating must be confirmed for the actual application.
Standards
● Design and Performance: EN 13828:2025 for applicable manually operated building water-supply ball valves
● Inspection and Testing: EN 12266-1
● Thread Connection: ISO 228-1
● Optional Thread Standards: ISO 7-1 or ASME B1.20.1 NPT upon request
● Gas-Service Option: EN 331 only when specifically designed, tested, and approved for gas service
A standard water-service brass ball valve should not automatically be treated as an EN 331 gas valve.
Industry Applications
● Domestic and commercial water supply
● Building plumbing
● HVAC water circulation
● Agricultural irrigation
● Water treatment auxiliary systems
● Compressed air pipelines
● General utility systems
Suitability for drinking water, gas, oil, steam, or chemical media should be confirmed according to the brass grade, seat and seal materials, pressure, temperature, and required approvals.
