ABSTRACT:
A primary valve has an open position for effecting operation of a milking means remover upon completion of a milking operation. A secondary valve has a first position for causing a pneumatic actuator to maintain the primary valve closed in response to normal milk flow from the milking means and has a second position for causing the actuator to open the primary valve in response to substantial cessation of the milk flow. Means associated with the actuator are operable upon said opening of the primary valve to keep it open regardless of the position of the secondary valve.
