Features:

- Porting pattern to DIN 24 340, from D,ISO 5781

and CETOP-RP 121H

- Pilot operated check valve, leak-free,- FD Balance Valve

controls the returning flow q V2 in relation to the flow being

directed into the opposite side of the actuater q V1 . With

cylinders the area tratio( q V2 = q V1 ϕ ) has to be taken into

account,

- By-pass valve, free-flow in opposite direction,

- Optional built-in secondary pressure relief valve

(only for valve with flange connections).


FD Balance Valves are used in hydraulic systems to influence the speeds of hydraulic motors and cylinders

independent of the load (prevents running away). In addition there is an isolator function for pipe burst safety.It comprises basically of the housing (1), main poppet (2), pilot part (3), pilot spool

(4), damping spool (5) and pilot damping (6).
