PROKOSCH ball valves are suitable for granulated and powdered media as well as neutral liquids, suspensions and gases. They are characterised by the use of fewer individual parts and space-saving elements as well as easy switchability and long service life.
The free passage reduces flow resistance to a minimum and the ball bearing on both sides reduces wear on the ball seats and ensures a uniformly low switching torque over the entire pressure range.
Thanks to a sensible modular principle, the ball valve is easily configurable and our standard designs and options allow a wide range of applications. Due to the fact that the ball valve does not have its own ignition source, it can also be configured for safe use in various ATEX applications.
