The Counterbalance Valve model series CBPP is a differ­ential area, direct acting, screw in cartridge style, non-vented, poppet type, adjustable, pilot assisted, hydraulic counterbalance valve with thread 7/8-14 UNF (CBPP-10…) or 20“x“1.5“mm (CBPP-20M…) are size SAE 10 / NG 8. This valve controls a moving load, preventing it from running ahead of the pump. Locking the load in any position, it also provides static overload and thermal expansion protection. This valve is a modulating device that allows free flow from port 2 to port 1, then blocks reverse flow until a pilot pres­sure inversely proportional to the load pressure is sensed at port 3 modulating flow from port 1 to port 2. Back pres­sure at port 2 adds to the spring setting (pilot ratio +1) x back pressure.

All external parts of the cartridge are zinc plated and chromited (CrVI−free).
