EV58-34 Valve

SYMBOL:
EV58-34 Valve symbol

DESCRIPTION
A spool-type, screw-in, cartridge-style, hydraulic directional element, with multifunction
potential when used with other directional, pressure, or flow control devices.

OPERATION
The EV58-34 is a spring-biased blocking valve which will shift to allow full flow from 1 to 2 only
when port 3 is vented to create a pressure drop across the internal orifice which exceeds the
pressure of the bias spring value.

FEATURES
• Multiple function/application potential.
• Low pressure drop.
• Compact size.
• Industry-common cavity.
