Pilot Relief Valve
hydraulic cartridge valve,Hydraulic pilot relief Valve PRV3
The value prevents flow from 1 to 2 until pressure at 1 exceeds the set crack pressure and opens the pilot section. The pilot flow creates a pressure differential across the spool which causes the value to open allowing flow from 1 or 2 protecting the circuit from over pressurization.
