DESIGN THEORY FOR G-π
BRIDGE
RELIEF VALVE
WITH ZERO
OVERRIDE*
Abstract: A new construction of the relief valve is presented with pilot G-p bridge hydraulic resistances network. The design theory of G-p bridge relief valve is studied and the formulas for designing the relief valve with zero static pressure override are obtained. The static performances of the relief valve are experimentally investigated. The theoretical and experimental results show that the static pressure override of the developed relief valve can be zero, i.e. when the overflow increases the control pressure is kept constant.
