Technical Feature
OPERATION:
The valve is normally closed pressure regulating valves. When the pressure at the inlet
(port ① ) reaches the valve setting, the valve starts to open to tank (port ② ), throttling
flow to regulate the pressure. They provide a vent port (port ③) that connects between
the main piston and pilot stage to provide for remote control by other pilot or 2-way
valves. These valves are accurate, have low pressure rise vs. flow, they are smooth
and quiet, and are moderately fast. -
