What are the common sizes and pressure ratings available for brass angle valves?

Brass angle valves come in a variety of sizes and pressure ratings to accommodate different plumbing system requirements. Here’s an overview of the most common specifications:

Common Sizes of it

Brass angle valves are typically sized based on the nominal pipe size (NPS) or diameter of the connection. The most common sizes include:

1. 1/4 inch (6 mm)
   • Used for small appliances like refrigerators or water dispensers.
2. 3/8 inch (10 mm)
   • Commonly used for connecting supply lines to faucets, sinks, and toilets.
3. 1/2 inch (15 mm)
   • The most widely used size for residential and commercial plumbing systems, suitable for sinks, showers, and washing machines.
4. 3/4 inch (20 mm)
   • Used for larger applications, such as water heaters, outdoor faucets, or main supply lines.
5. 1 inch (25 mm)
   • Typically used in industrial or commercial settings for high-flow applications.

Pressure Ratings of it

Pressure ratings indicate the maximum pressure the valve can withstand without failing. Brass angle valves are designed to handle a range of pressures, depending on the application. Common pressure ratings include:

1. 150 PSI (10.3 bar)
   • Standard rating for most residential plumbing systems. Suitable for low to medium-pressure applications.
2. 200 PSI (13.8 bar)
   • Used in systems with higher water pressure or in commercial settings.
3. 300 PSI (20.7 bar)
   • Designed for high-pressure applications, such as industrial plumbing or heavy-duty commercial systems.
4. 600 PSI (41.4 bar)
   • Used in specialized industrial applications where extremely high pressure is required.

Additional Considerations

• Thread Standards: Brass angle valves are available with different thread types, such as NPT (National Pipe Thread) or BSP (British Standard Pipe), to match regional plumbing standards.
• End Connections: Valves may have compression, threaded, or push-fit ends to suit different piping materials (e.g., copper, PEX, or PVC).
• Temperature Ratings: Most brass angle valves are rated for temperatures up to 250°F (121°C), making them suitable for both hot and cold water systems.

Summary:

The most common sizes for brass angle valves are 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, and 1 inch, while pressure ratings typically range from 150 PSI to 600 PSI. Selecting the correct size and pressure rating ensures optimal performance and compatibility with your plumbing system. Always check local codes and standards to ensure compliance.
