Noise protection taken seriously
Sound insulation is considered an important and value-determining characteristic for the quality of buildings. It is required by building regulations for most types of buildings and is regulated in DIN 4109. Water vortices created in fittings lead to flow noises that are transmitted to the building. Especially in modern buildings, these noises are perceived as unpleasant and stress-inducing.

HSE^®Uniwater ball valves in dimensions 3/8″-2″ are DVGW-certified under registration number NW-6102AT2438 and have noise class I, P-iX 18536/I. The dead space-optimised fitting ensures that no legionella formation is possible. DIN face-to-face lengths allow easy replacement with DIN free-flow valves. The material used, CW 617 N, is also permitted for use in domestic water systems after 11/2013.

HSE^®ball valves made of MS 58 are available in various pressure ratings and handle variants and are suitable for a wide range of applications in heating and industrial systems. We offer ball valves with thread, with screw connections, with solder connection and with press connection. The ball valves have a PTFE seal on the ball and on the spindle with a retractable packing gland and are therefore absolutely leak-proof over a long period of use.
