Abstract: A method for operating a valve, comprises directing fluid flow through a housing of the valve, wherein the fluid flows into the housing through a housing inlet and flows out of the housing through a housing outlet. The method continues by directing a first electric current into a solenoid coupled to the housing to generate a first magnetic field, wherein the first magnetic field exerts a force upon a plunger positioned inside the housing and causes the plunger to magnetically connect to a magnet. The method continues by directing a second electrical current into the solenoid to generate a second magnetic field, wherein the second magnetic field exerts a force upon the plunger causing the plunger to disconnect from the magnet and engage with the housing outlet. Fluid flows into the inlet through a milking hose, and fluid flows out of the outlet into a milking pipeline.

Abstract: A valve apparatus comprises a housing, a solenoid operable to receive electrical current flow, and an enclosure, the enclosure housing the solenoid, a magnet coupled to the enclosure, a plunger comprising a stopper and a conductive portion, and a spring coupled to the plunger. When the solenoid receives a first current, the solenoid applies a first magnetic force onto the plunger causing the stopper to disengage from the housing outlet, the conductive portion of the plunger magnetically connects with the magnet, and the stopper remains disengaged from the housing outlet after the first period of time expires. When the conductive portion is magnetically connected to the magnet and the solenoid receives a second current, the solenoid applies a second magnetic force onto the plunger causing the conductive portion of the plunger to disconnect from the magnet so that the stopper engages with the housing outlet.
