Technical Feature
OPERATION:
The valve is normally closed, pressure-limiting valves used to protect hydraulic
components from pressure transients. When the pressure at the inlet (port ① ) reaches
the valve setting, the valve starts to open to tank (port ② ), throttling flow to limit the
pressure rise. These valves are smooth and quiet, essentially zero leak, dirt tolerant,
immune to silting and are very fast. -
