Operation Symbol of ICBBA-LHN Counterbalance Valve

Operation Symbol of ICBBA-LHN Counterbalance Valve

One-way function: The ICBBA-LHN allows the flflow from ② to ①, and blocks flflow  from ① to ② when the pressure of ① is lower than the check spring setting. Relief valve function: The cartridge relieves flflow from ① to ② when the pressure  of ①exceeds the check spring setting.


Pilot-assisted restriction function: When there is pilot-assisted pressure at port ③, it could change the opening degree from ① to ② to achieve the restriction  function.
