The first stem including a first slotted opening extending from the first distal stem end into the first stem. The rotary valve includes a second ball valve including a second stem extending from a second proximal stem end to a second distal stem end outward from the second ball valve. The second stem including a second slotted opening extending from the second distal stem end into the second stem. The second stem extends towards the first stem. The rotary valve includes a drive key of non-uniform thickness located within the first slotted opening and the second slotted opening. The drive key operably connects the first ball valve to the second ball valve.

A coolant control ball valve assembly comprises a housing that includes a housing chamber. The coolant control ball valve assembly further comprises a channel and a plurality of ports that extend from the housing chamber, and a valve element positioned in line with the channel and the plurality of ports. Additionally, the coolant control ball valve assembly comprises an actuator assembly in communication with the valve element. The actuator assembly includes an expansion element, and linear translation of the actuator assembly results in rotational translation of the valve element. Further, the coolant control ball valve comprises a flow diverter positioned adjacent the valve element. The flow diverter allows for coolant to reach a minimum velocity around the expansion element.

The housing includes fastening parts formed integrally with the housing main body and fastening holes formed in correspondence with the fastening parts. The housing main body is fixed to a heating element with fastening members passed through the fastening holes and screwed to the heating element. The fastening holes include at least three fastening holes. The opening of an inlet port is formed inside a triangle that is formed by connecting the three fastening holes.

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.

The invention concerns a system for the circulation of fluid between at least one first body or housing (2) and at least one second body or housing (3), comprising an arrangement of multiple fluidic connections (4, 4′, 4″, 4′″) between, on the one hand, said first body or housing (2) provided with at least two mutually distinct openings (5, 5′, 5″, 5′″) and, on the other hand, at least one second body or housing (3) also having mutually distinct openings, each connection establishing a leaktight fluidic connection between an opening of the first body or housing (2) and an opening of the second body or housing (3), or of one of the second bodies or housings.

In this system (1), each of the fluidic connections (4, 4′, 4″, 4′″) is of a rigid but articulated type, and formed by successive nestings of a rigid female manifold (7, 7′, 7″, 7′″), a rigid duct or diabolo (9, 9′, 9″, 9′″) and a rigid male fitting (8, 8′, 8″, 8′″).

A control valve includes a casing, a valve body, and a seal cylindrical member. The casing includes an inlet and an outlet. The valve body is rotatably disposed inside the casing and includes a circumferential wall portion in which a valve hole that allows the inside and outside to communicate is formed. The seal cylindrical member includes one end portion which communicates with a downstream side of an outlet and the other end portion on which a valve sliding contact surface is provided. In the other end portion of the seal cylindrical member, a protrusion height changes continuously in a circumferential direction along a shape of an outer circumferential surface of the circumferential wall portion. A thick portion which is thicker compared to other portions is provided in a region of the other end portion of the seal cylindrical member at which the protrusion height is high.

A directional flow control device includes a housing extending along a longitudinal axis between an inlet end and a discharge end. The housing holds stator magnets. The directional flow control device includes a flow deflector received in the housing. The flow deflector is rotatable in the housing about a rotation axis parallel to the longitudinal axis. The flow deflector has a flow channel therethrough. The flow channel has an intake bore at a front end of the flow deflector and a discharge bore at a rear end of the flow deflector. The intake bore is coaxial with the rotation axis. The discharge bore is offset from the rotation axis. The flow deflector has rotor magnets aligned with and facing the stator magnets. The stator magnets are energized to cause rotation of the flow deflector relative to the housing.

A valve device for controlling a fluid flow, in particular an air flow, having at least one inlet and at least two outlets, at least one of the outlets being fluidically connectable in each case to the inlet via a through-channel of at least one manipulable guide means. The through-channel of the guide means can be changed at least indirectly via a control fluid flow either with regard to at least a section of its internal cross section or can be rotated at least to a limited extent with regard to its orientation with respect to the outlets and the inlet can be rotated at least to a limited extent.

A control valve includes: a port, which is shaped in a tubular form; a valve element; and a metal seal, which contacts the valve element. A gap is formed between a tubular portion of the metal seal and the port in a perpendicular direction that is perpendicular to an axial direction of a flow passage of the port. Thereby, when the valve element is displaced in the perpendicular direction, the valve element urges the metal seal to displace the metal seal in the perpendicular direction in the state where the metal seal contacts the valve element.
