A flange-mounted inline valve arrangement includes a flange having an internal fluid passage, and an inline electrically-operable valve coupled to the flange. The inline valve includes a valve body and a valve member movable relative to the fluid passage in the flange for controlling flow. The valve arrangement also includes an electrical feed that connects to the electrically-operable valve through the flange for enabling an electrical connection external to the flange and other system piping. At least part of the electrical feed may be in a flow path and is fluidly sealed to prevent electrical shorts. The valve arrangement may be installed into the system as a single unit with an exterior coupling of the electrical feed on an exterior part of the flange to easily make the external electrical connection. The valve arrangement may be used in a chiller, where the inline valve is an electronic expansion valve.

An electronic modulating valve for a refrigerant system including a valve body; an electrically actuated valve member mounted in the valve body for modulating flow of fluid through the valve body; an electric power element having at least a portion of an electric actuator; and an electronic controller operably connected to the actuator, in which the actuator is operably connected to the valve member to control movement of the valve member in response to commands from the controller. The valve may include a probe configured to sense a mechanical vibration in the system and/or a refrigerant leak sensor. The controller receives information from the probe and/or leak sensor and controls movement of the valve member via the actuator in response to the information. The controller may be configured with a closed-loop logic architecture to control movement of the valve member via the electric actuator.

A hoseless sensor system for a refrigerant unit includes a plurality of hoseless sensors for sensing system parameters of the refrigerant unit, and a portable electronic device configured to receive the system parameters from the hoseless sensors and to calculate system conditions for the refrigerant based on the system parameters. The plurality of hoseless sensors includes a hoseless first pressure sensor and a hoseless second pressure sensor, and a hoseless first temperature sensor and a hoseless second temperature sensor. The temperature sensors may be temperature sensor clamps. Each temperature sensor clamp includes a clamping portion configured to clamp on a tube of the refrigerant unit, the clamping portion including a sensor element to measure temperature about the tube. The clamping portion further includes a plurality of clamping teeth, and adjacent clamping teeth interlock in an overlapping configuration when the clamp closes inward beyond a threshold point.

A refrigeration system includes a compressor, a condenser, a receiver, an expansion device, and an evaporator in fluid communication with one another. An electronic condenser pressure control valve is in fluid communication with an outlet of the condenser and operative to control a condition at the outlet of the condenser. A controller is operatively coupled to the electronic condenser pressure control valve, the controller including logic configured to operate the electronic condenser pressure control valve to dynamically float the discharge pressure at the condenser outlet based on at least one of one or more system conditions or one or more ambient condition.

An electronically controlled stepper motor valve utilizes an electric feed through assembly providing electrical connection between the stepper motor and a mating cable connector; wherein the electric feed through assembly includes four individual leads that are sequenced to allow the mating cable connector to be installed in any of four positions, each 90 degrees apart. The ability to use a 90 degree elbow style cable connector allows the EEV footprint to be minimized which provides an advantage when the electric expansion valve is installed in the tight confines of a package system.
