Product Description
A
1-1/4" (32mm) Brass Ball Valve is a heavy-duty, quarter-turn manual shut-off valve designed to control, isolate, and regulate fluid flow within a pipeline. Featuring a
1-1/4 inch nominal port size, it is widely used in residential, commercial, and industrial plumbing systems to manage water, oil, gas, and compressed air. [

Core Technical Specifications
Fluctuations in pressure and temperature ratings occur depending on the specific application (e.g., water vs. gas) and standard vs. lead-free brass formulations. [

- Pressure Rating: Typically rated up to 600 PSI WOG (Water, Oil, Gas) for non-shock applications and 150 PSI WSP for saturated steam.
- Temperature Range: Operates effectively from -20C to 120C (-4F to 248F) depending on the seal material.
- Connection Standards: Commonly configured with Female-to-Female (F-F) threads, utilizing either BSP (British Standard Pipe) or NPT (National Pipe Tapered) standards.
- Nominal Sizing: Identified internationally as DN32 (Diameter Nominal 32mm). [1, 2, 3, 4, 5, 6, 7, 8]
Key Design Features
- Quarter-Turn Mechanism: Features a top lever handle that pivots exactly 90 degrees. When the lever is parallel to the pipe, the valve is fully open; when perpendicular, it is completely closed. [1, 2, 3, 4, 5]
- Full Port / Full Bore Design: The internal hollow ball matches the 1-1/4" inside diameter of the connected pipe. This prevents flow restriction, reduces friction loss, and maintains maximum system pressure. [1, 2, 3, 4]
- Forged Brass Construction: Forging the brass body minimizes structural porosities and micro-fissures compared to standard cast valves, making it exceptionally resilient against mechanical stress and cracking. [1, 2, 3, 4, 5]
- PTFE Seating & Seals: Outfitted with premium Teflon (PTFE) seats surrounding the chrome-plated brass ball. This guarantees a 100% leak-proof seal and ensures low operational torque even after long periods of disuse. [1, 2, 3, 4]
Common Industrial & Domestic Applications
- Main Water Lines: Acting as the master shut-off valve for residential buildings or commercial facilities due to its high-volume capacity.
- HVAC & Solar Systems: Managing hot and cold water circulation lines in climate control and radiant heating systems.
- Gas & Fuel Pipelines: Safely isolating gas connections in heavy-duty commercial equipment and mechanical systems. [1, 2, 3, 4, 5]
