Description

Designed to provide dependable isolation in high pressure systems where corrosion resistance and long-term reliability are essential. Manufactured from dezincification resistant brass, it offers improved durability in aggressive water conditions compared to standard brass valves, making it particularly suitable for potable water and demanding industrial applications. The full bore design ensures unrestricted flow through the valve, reducing pressure drop and maintaining system efficiency. This makes it an excellent choice for installations where flow performance is critical, such as distribution lines, plant systems, and process applications.

The threaded BSP taper connection allows for secure, leak-resistant installation across a wide range of pipework systems. The robust two-piece construction also allows for easier maintenance while maintaining structural strength under pressure. An anti-blow-out stem enhances safety by preventing stem ejection under pressure, while PTFE seats provide smooth operation and reliable sealing over repeated use. With a working pressure of up to 40 bar and a broad temperature range from -20°C to +130°C, this valve is well suited to both hot and cold service conditions.

Typical Applications

  • Water Distribution Systems: Ideal for isolating flow in potable and non-potable water networks.
  • Industrial Pipework: Suitable for high pressure process lines and plant installations.
  • Heating and Cooling Systems: Handles both hot and cold media reliably.
  • Compressed Air Systems: Full bore design supports efficient flow.
  • General Mechanical Services: Dependable shut-off across a wide range of engineering applications.
