Parker Gresen DS-75 Hydraulic Selector Valve
1. Product Overview
The DS-75 is a lever-operated hydraulic selector (diverter) valve from Parker Hannifin's Gresen line. It is a 4-way, 2-position spool valve with a single spool directly actuated by a hand lever, directing pump flow to the selected circuit — switching one hydraulic source between two actuators/circuits.
The body is high-tensile cast iron and the spool is chrome-plated for wear and corrosion resistance. Standard ports are 3/4" NPTF (SAE-12 optional). Compact, direct-operated and rugged, it is widely used on mobile machinery, agricultural equipment and industrial power units where manual circuit selection is required.
With the standard 3/4" NPT configuration, max pressure is about 2000 psi (~140 bar) and max flow about 35 gpm (~132 L/min); with SAE ports the pressure rating can reach about 3000 psi at a recommended input flow of about 25 gpm.
