Product Overview
Hydraulic Exclusion Valve PDV25
The PDV25 hydraulic exclusion valve is engineered to optimize hydraulic system efficiency by discharging excess flow during low-pressure, high-flow operations. It facilitates seamless oil supply to steering and hydraulic circuits with minimal pressure drop. Designed for robustness in agricultural and heavy machinery, it automatically redirects pump flow to the tank in response to system pressure changes.
