EV16-S34

DIRECTIONAL ELEMENT, VENTED

Overview

Description

The EV16-S34 is a screw-in, cartridge style, hydraulic directional element.

Operation

The valve is a spring-biased blocking valve with an internal pilot orifice. The EV16-S34 shifts to allow full flow from port 1 to port 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.

note: orifice disc should not be used with this product.

Features

  • Multiple function/application potential.
  • Smooth shift transition.
  • Low pressure drop.
  • Tall cap version for higher bias springs 90, 110 and 160. The tall cap is also required when the valve is specified with manual override and the 40 size bias spring. Extra tall cap version for bias spring 240.
  • Optional manual override only for 40, 90, 110, 160 and 240 psi bias springs.
  • "G" metering option for metered flow control when opening.
  • Industry common cavity.
