1. guarantees great outputs and small load loss. 2. tests under hard working conditions.

The S-valve is the first choice for concrete pressures above 85 bars. This is especially useful for long pumping distances over stationary pipelines. The Putzmeister S-valve is especially designed for long life and high concrete pressure. This results in long service intervals and increased availability of the machine. To extend the life of the S-valve, the inside wall can be rebuilt by hard face welding.
