Description
Reliable, full-bore isolation valve designed for fast, secure installation on compatible press-fit pipework systems. Manufactured from dezincification-resistant (DZR) brass, it provides strong long-term performance in water services and other suitable pipework applications where corrosion resistance, dependable shut-off and installation efficiency are important. Supplied with a black lever handle and in M press profiles, this valve is designed to suit installers working with standard M profile pressing tools.
The full-bore design helps maintain flow through the valve, reducing unnecessary restriction compared with reduced-bore alternatives. This makes it a strong choice for commercial, industrial and building services pipework where reliable flow control is required. A non-press leak detection system helps identify unpressed joints during testing, supporting safer and more reliable installation checks before the system is fully commissioned. The valve is also WRAS approved, making it suitable for applicable potable water installations when installed correctly as part of a compliant system.
