As the inlet pressure approaches the set pressure, the force of fluid pushing up the valve [4] approaches the
force of the spring [6] pressing down the valve [4]. When the inlet pressure increases further, the valve [4]
opens and discharges the fluid. The valve lift changes responding to the inlet pressure and controls it.
