Ball Valves

The HYDAC Compatibility List provides a general guideline for selecting suitable materials for housing, spindles, seals, and internal components in 2/2-, 3/2-, and 4/2-way ball valves. Based on supplier data and test experience, it helps users make informed material choices for various fluids and operating conditions. This reference is non-binding and intended to support material selection across a wide range of applications.
