ABSTRACT:
A liquid dispensing device including a body generally having an actuator cavity and a liquid passage. A valve seat element is connected to the body and a valve stem is mounted for movement within the body with respect to the valve seat element. Inner and outer magnetic elements are disposed around the periphery of the valve stem to couple the valve stem to the valve actuator. The inner magnetic element is connected to the valve stem for movement with the valve stem within the body. The outer magnetic element is connected with an actuator and is slidable within the body in response to, for example, pressurized air being applied against the actuator. The magnetic elements couple the valve stem to the actuator and eliminate the need for a dynamic seal between the valve stem and body.
