Web6 de nov. de 2024 · How does a counterbalance valve work? Counterbalance valves are hydraulic devices that function using this basic principle: fluid can freely flow through a check valve into the actuator, and reverse flow will be blocked using a relief valve until a pre-set pressure is reached that is set based on the system pressure and load capability. 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 ...
