Plasson DZR Double Check Valve WRAS FI x FI 1" PV9077300

This double check valve is constructed from DZR brass and fitted with BSP female threads at both ends, making it suitable for integration into potable water plumbing systems. It is commonly used to prevent backflow, helping to protect supply lines from potential contamination by allowing water to flow in only one direction.

On site, the valve is typically installed on supply pipes near appliances and fixtures where there is a risk of reverse flow. Its straightforward design enables quick installation during repairs or new system builds, supporting reliable operation for everyday plumbing tasks.
