A solenoid-operated, 3-way, direct-acting, spool-type, screw-in hydraulic directional valve designed for high pressure operation up to 345 bar (5000 psi).
When de-energized, the SV58-30 allows flow from ➁ to ➀ while blocking flow at ➂When energized, the cartridge’s spool shifts to open from ➂ to ➁, while blocking flow out ➀Note: Port ➀ must be connected to tank. Valve cannot withstand more than 276 bar (4000 psi) at the inlet of port ➀
