WebIn statics, the valve is described with the equation. Counterbalance valve, classified by type, is an internally-externally piloted valve because both the pilot pressure and the load pressure tend to open the valve. After minor rearrangements, Equation 1 takes the form. p s e t = F 0 / A l o a d c p = c / A l o a d k p i l o t = A p i l o t / A ...
