DIRECTIONAL VALVES
ECR16-S35 Piloted Logic Element w/Built-in Relief
DESCRIPTION
A spool-type, screw-in, cartridge-style, hydraulic directional element, with a built-in,
non-adjustable pressure relief valve.
OPERATION
The ECR16-S35 is a spring-biased blocking valve which will shift to allow full fl ow
from
➀ to ➁ only when pressure at ➀ exceeds the cumulative pressure of ➂, plus the
bias spring pressure value.
If the pressure at
➀ and ➂ exceeds the relief valve setting, the valve operates as a
relief valve, opening the
➀ to ➁ fl ow path.
FEATURES
• Multiple function/application potential.
• Low pressure drop.
• Industry common cavity.
