Product Operation Symbol
The Counterbalance Valve 30PH-Y300-1.0 permits flow from 2 to 1, but prevents it from occurring from 1 to 2. Pilot pressure at port 3 causes the main spool to move higher, opening the 1 to 2 flow route. Pilot pressure, spring seat angle, and spring stiffness all affect how the cartridge flows.
