The nut–screw ball valve with butterfly handle from the F-COMFORT collection is a compact control element for water installations, designed for DN15 systems with a G1/2 connection. It works in domestic and technical networks where reliable shut-off and easy identification of circuits are important.
The brass body with a flow coefficient Kvs of 5.34 m³/h supports efficient water distribution, while the pressure rating of 20 bar and operating temperature up to 100°C suit demanding conditions. The integrated gland improves tightness over time, and the non-full-bore design fits applications where precise throttling of water flow is required.
The body is made of CW617N-4MS brass with reduced lead and nickel content, and all media-contact surfaces are nickel free, which aligns with modern drinking water standards. The brass ball works with PTFE seals on both the ball and stem, giving smooth operation and resistance to wear. The nut–screw connection simplifies assembly in existing pipework, and the butterfly handle is convenient in confined spaces.
Advanced Body Technology, replaceable bands for marking hot/cold or supply/return lines, and informative tags under the handle support clear installation labelling, thanks to which service work becomes more intuitive. Awarded the Gold Medal at the Installation 2020 fair, this F-COMFORT ball valve is a solid choice for professional and home water systems.
