A flow control device for controlling flow in a heating, ventilation, or air conditioning (HVAC) system is shown. The flow control device includes a valve body including an inlet path, an outlet path, a valve member, and a valve stem coupled to the valve member. The flow control device includes a first sensor configured to obtain pressure measurements within the valve body, a second sensor configured to obtain displacement measurements of the valve stem, and a controller including a processing circuit configured to determine a flowrate based at least on the pressure measurements from the first sensor and the displacement measurements from the second sensor.

Flowrate determination system and method for a flow control valve

A system for controlling a flow rate of a fluid through a valve is provided. The system includes a valve and an actuator. An actuator drive device is driven by an actuator motor and is coupled to the valve for driving the valve between multiple positions. The system further includes a differential pressure sensor configured to measure a differential pressure across the valve and a controller that is communicably coupled with the differential pressure sensor and the motor. The controller is configured to receive a flow rate setpoint and the differential pressure measurement, determine an estimated flow rate based on the differential pressure measurement, determine an actuator position setpoint using the flow rate setpoint and the estimated flow rate, and operate the motor to drive the drive device to the actuator position setpoint.

Systems and methods for flow estimation using differential pressure sensor across valve

A building management system is configured to modify an environmental condition of a building. The building management system includes a valve assembly, an actuator device, and a network sensor device. The actuator device includes a motor, a drive device driven by the motor and coupled to the valve assembly, and a controller coupled to the motor. The controller includes a microprocessor and a control application configured to enable closed loop control of the valve assembly. The network sensor device is communicably coupled to the actuator device and configured to measure an environmental property. The control application is configured to perform the closed loop control of the valve assembly based on an input control signal from a mobile device and the measured environmental property from the network sensor device.

Integrated smart actuator device

A valve assembly is provided. The valve assembly includes a valve body having a valve chamber and a plurality of ports into the valve chamber. The plurality of ports include a first port, a second port, and a third port. The first port and the second port are aligned with a common axis and located on opposite sides of the valve chamber. The system further includes a valve member located within the valve chamber. The valve member is a rotatable ball having a fluid passage that extends through the ball and includes an opening at the end of the ball. The fluid passage is substantially oval-shaped when viewed at the opening in a direction parallel to the fluid passage. The valve assembly further includes a valve stem that is coupled to a valve member and has a first end that extends from the valve body.

A multipurpose valve tool is provided. The multipurpose valve tool includes multiple flow control discs, a retention ring, and a valve key. The flow control discs are configured to be installed within a valve body of a valve assembly to modulate a flow of fluid through an outlet port of the valve body. The retention ring is configured to retain the flow control discs on a component of the valve assembly when the flow control discs are not installed within the valve body. The valve key includes a first end configured to engage an installation feature in a retention fastener for one of the flow control discs. The flow control discs, the retention ring, and the valve key are detachably coupled to each other.

A home RO filtration system includes a membrane module having an inlet connected to a feed line, the membrane module also having a concentrate outlet coupled to a concentrate line, and a permeate outlet coupled to a permeate line. The permeate line communicates with a faucet. The system includes a flush reservoir communicatively coupled between the permeate line and the feed line. The system is configured such that after the faucet is turned off, a portion of permeate is delivered to the reservoir and then delivered to the inlet of the module to flush the module.

Method and system to flush an RO system

A filtration assembly includes a feed water line and a permeate line. A shut-off valve is coupled between the permeate line and the feed water line and operative to open the feed line when the faucet is opened based on a pressure differential between the feed line and the permeate line. An energy storage member is located within the permeate line and configured to compress and then expand after the faucet is closed causing the shut-off valve to fully close.
