Product Description

Rexroth DR10-5-52/100Y R900596766

The Rexroth DR10-5-52/100Y R900596766 is a direct operated pressure reducing valve, 3-way version, designed for subplate mounting. It is primarily used in hydraulic systems to maintain a constant, reduced pressure in a secondary circuit, regardless of higher and often fluctuating pressures in the main system. This valve reduces the pressure from port P to port A based on the setting adjusted via the rotary knob with scale. The third port, T (tank), facilitates the drainage of control oil or excess flow if the pressure in the secondary circuit (port A) attempts to exceed the set value due to external forces.
