Abstract: Exemplary embodiments are directed to modular solenoid valve kits and associated methods, generally involving a valve body that includes a plurality of actuator section components and a plurality of head section components. The plurality of actuator section components includes a drive solenoid, a solenoid return spring, a stroke calibration collar and an actuator-to-head calibration collar. The plurality of head section components includes a needle, a stem return spring, a seal and a seat. The plurality of actuator section components and head section components are adapted to be interchanged to create a pull-through normally open valve, a pull-through normally closed valve, a push-in normally open valve and a push-in normally closed valve. That is, the kits and methods allow for modification of one valve type (e.g., a pull-through normally open valve, a pull-through normally closed valve, a push-in normally open valve and a push-in normally closed valve) into a different type.

Abstract: Exemplary embodiments are directed to apparatus, systems and methods used in connection with a needle valve device operating in a pressurized flow system. The apparatus, systems and methods provide for automatic positioning of a needle relative to a seat in the needle valve device to provide consistent calibration with minimal user interaction after a maintenance event or upon a start-up of the pressurized flow system. The apparatus, systems and methods utilize a calibration collar secured to a shaft of an actuator within the needle valve device. The calibration collar includes one or more locking mechanism and a spring.

Abstract: Exemplary embodiments of the present disclosure are directed to limiting a rate or pressurization in a reconfigurable pressurized flow system for which different system configurations can have different system volumes. In exemplary embodiments, the system can determine a limit for the rate of pressurization by configuring the system for a closed system rate of pressurization, measuring the closed system rate of pressurization at a set flow rate, and determining a relationship between the closed system rate of pressurization and the flow rate. The system can use the relationship to dynamically set the limit for different flow rates in the system.

Abstract: Described is a method of reducing liquid composition errors in a low-pressure mixing pump system. Packets representing the switching intervals of each component of the desired fluid mixture are provided to an intake of the mixing pump system. For each packet, a switching time associated with at least one of the components in the packet is modulated. Modulated switching times are based on time offsets that are specifically selected according to the undesirable frequency characteristic of an intake response of the mixing pump system. The average of the volumes contributed by the packets thus modulated is equal to a component volume that achieves a desired proportion of the component in the output flow of the mixing pump system. Modulated switching times enable the reduction or elimination of composition error in the output flow of the mixing pump system.
