HSE® Uniwater system ball valves
HSE® Uniwater system ball valves with external threads on both sides facilitate compliance with the installation regulations of DVGW Code of Practice W 570. The ball valves can be connected with all half screw connections of the commercially available press connections and can therefore be replaced without changing the pipe routing.
When using the version with drain, there is no need to create an additional connection for a KFE valve to drain the system.
All ball valves are available in 3 different handle variants and also complete with Viega-Profipress® screw connection.
