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).
