DIRECTIONAL VALVES
HEP16-S35 HyPerformance
TM
Piloted Spool-Type
PERFORMANCE (Cartridge Only)
SYMBOL
4.502.3
DESCRIPTION
A high-pressure spool-type, screw-in, cartridge-style, hydraulic directional element,
with multi-function potential when used with other directional, pressure, or fl ow control
devices.
OPERATION
The HEP16-S35 is a spring-biased blocking valve which will shift to allow full fl ow from
to only when pressure at exceeds the cumulative pressure of , plus the bias
spring pressure value.
HEP16-S35 is a pilot-to-close directional valve.
With no pressure at
, fl ow will be allowed from to once the bias spring force
is overcome with pressure at
.
FEATURES
Multiple function/application potential.
Low pressure drop.
x All HyPerformance products are tested to the rigorous standards
of the NFPA specifi cation T2.6.1.
All HyPerformance valves are tested at a verifi cation level of 90%
and an assurance of 99%.
