The Rexroth DA 10-2-56/200-17 (R900597015) is a high-performance, pilot-operated pressure cut-off valve designed for subplate mounting. This valve is a critical component in hydraulic systems for achieving energy-efficient pump circulation. It functions by automatically switching the pump from a high-pressure operating mode to a no-pressure circulation once the pre-set system pressure is reached, thereby reducing power consumption and heat generation. This model includes an integrated check valve, which allows for unrestricted free flow from channel B to A. Its robust construction ensures reliability and longevity in demanding industrial applications.
