Operation
The valve controls moving load and preventing it from running ahead of the
pump,locking the load in any position,it also provides static overload
and the mal enpansion protection.The valve allows free flow from ② to ①
and blocks reverse flow unit a pilot pressure proportional to the load pressure
is sensed at ③ modulating flow from ① to ② .
