HYDRAFORCE EV58-34 Vented Directional Element.
A spool-type, screw-in, cartridge-style, hydraulic directional element, with multi-function potential when used with other directional, pressure, or flow control valves.
The EV58-34 is a spring-biased blocking valve which will shift to allow full flow from ➀ to ➁ only when port ➂ is vented to create a pressure drop across the internal orifice which exceeds the pressure of the bias spring value.
