DIRECTIONAL ELEMENT, VENTED
Overview
Symbol
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.
