RU - DAFRAM multi-stage ball valves are equipped with an internal cage that splits the pressure drop into several stages. Each stage is made up of a drilled plate placed in the ball hole. The number and configuration of internal stages are defined to meet the working conditions specified by the customer, in order to ensure the best flow control capability.

Multi-stage ball valves are designed to operate against high pressure drops providing excellent control capability and noise attenuation during a long service life. Furthermore, thanks to DAFRAM proven experience, tight shut-off and zero external leakage are a fixed point.
