A contactless valve configured to dispense a liquid can include an actuator configured to move a plug between a closed position in which the plug prevents the flow of liquid through valve body, and an open position in which liquid can be dispensed through an outlet. The valve can include an activation sensor, a presence sensor, and a controller configured to control the actuator and in electrical communication with the activation sensor and the presence sensor. The controller can be configured to switch the presence sensor into the activated state in response to the detection of the prerequisite condition by the activation sensor, and to control the actuator to move the plug from the closed position to the open position in response to the detection of the object in the upper detection zone by the presence sensor.

A system and method for automatically controlling gas pressure for a plasma cutter includes a plasma torch, a gas supply system to provide a pressurized gas to the plasma torch, and a proportional valve configured to regulate the pressurized gas. The proportional valve includes a body, a valve seat positioned therein and defining a valve orifice, and a plunger having a mating surface on one end that mates with the valve seat and the orifice and a pressure receiving surface on an opposite end. The proportional valve also includes an inlet to receive the pressurized gas and distribute the pressurized gas to the valve orifice and the pressure receiving surface of the plunger, an electrical solenoid having a chamber to electro-magnetically translate the plunger therein, and a bias urging the plunger toward the valve orifice in conjunction with the pressurized gas when electrical power is reduced to the electrical solenoid.

A system and method for providing a high power density plasma cutting/welding-type system is disclosed. The plasma cutting system includes a housing and a power source disposed within the housing constructed to generate plasma cutting power. The plasma cutting system also includes a plasma torch actuated by a trigger and connected to the power source to produce a cutting arc. The plasma cutting system is constructed such that it has a power-to-weight ratio of at least 550 Watts per kilogram (W/kg).

A control unit for operating a valve system in a water conditioner system includes a drive motor having an output shaft coupled to the valve system, a valve position slide switch, an electronic regeneration controller, and a settable mechanical clock. The electronic controller can be programmed by the use of electrical jumpers/dip switches/control knobs. As the drive motor drives the output shaft coupled to the valve system, the drive motor also contemporaneously rotates a dual lead screw in the valve position slide switch. The dual lead screw drives an electrical contactor along a series of electrical contacts in a closed loop fashion. Each of the discrete electrical contacts corresponds to a position of the valve. The electronic controller controls the position of the valve in accordance with dwell times programmed into the electronic controller. If a demand regeneration scheme is desirable, a hardness setting rotary potentiometer can be used to provide analog electrical control.

Valve controller for water conditioning system

A water conditioner rotary valve for use in a water conditioning system includes a valve body constructed of an upper section, a lower section and a middle section, to facilitate ease in assembly of the body. The valve rotor member of the conditioner valve is driven by a Geneva drive system, to provide accurate positioning of the rotor member in its various positions. A valve seat member is located adjacent the rotor member, and provides a construction which improves the seal between the rotor member and the surface of the valve body adjacent thereto. The three-piece assembly of the valve body facilitates providing a valve capable of either upflow or downflow brining by replacing the lower valve section. A brine injector valve is mounted exteriorly of the valve body.
