Ball valves are proven in practice: wherever aggressive gases and liquids are safely and reliably shut-off, isolated, mixed or distributed, a ball valve is the ideal partner for various tasks. There is hardly any pressure loss when they are used and the power consumption is very low compared to other shut-off fittings. The high safety and reliability of the ball valves is due to their design features: the shut-off body comprises a ball with a hole drilled through it (which gives the valve its name). When the valve is open the entire cross-section is clear. The ball manufactured in one piece with the stem is centred by sealing sleeves; stem sealing using an O-ring provides sealing upward. All valves are manufactured as standard with female threads, a very wide range of connection modules can therefore be used. The valves are available in various plastics and in a wide variety of types – from the 2-way ball valve to the 5-way ball valve resulting in a wide range of possible applications in practice. 7-way, 9-way or 11-way ball valves are available as special versions.

Connection system

The Series 6 ball valves are supplied as standard with seam-less female threads. The EM-TECHNIK modular system provides numerous elements for the these threads to suit the specific application. The right connection for every application - on the pages for Series 1, 2 and 3 you will find a large range of connection systems for flexible tubes and pipes, fittings, couplings, adapters, etc..
