A valve (1) is introduced for a heat pump system in a motor vehicle, with at least one inlet (3), at least two outlets (2, 4) and a valve element (7) which comprises at least one throughlet (8) and at least one expansion recess (9) that can be brought into fluidic connection with at least one outlet (2, 4).

An L-ball union drain valve member utilizes a union member with an L-ball valve that is coupled to a tee-shaped valve body with a drain port. The drain port includes an additional valve member that permits the draining/purging/filling of the drain port. The orientation of the drain port can permit the draining/purging/filling of different sections of the valve assembly, depending upon orientation of the components. The union connection permits easy disassembly and installation of the components and differing position of the handle of the valve member with respect to the tee-shaped valve body.

A 3-way T-flow ball drain valve permits the draining/filling/purging of a hydronic or plumbing system at the end of the line. This permits the orientation of a drain port in either horizontal or vertical position while permitting end of line draining. A drain valve member is positioned to permit the opening of the drain port when the T-ball valve member in the tee-shaped valve body has been open to permit flow toward the drain port.

An embodiment integrated cooling control valve applied to a fuel cell thermal management system (TMS) includes a ball valve having at least three layers, wherein the ball valve includes a valve housing including a first port fluidly connected to a fuel cell stack, a second port coupled to a cathode oxygen depletion (COD) heater, a third port coupled to an ion filter, a fourth port coupled to a radiator, and a fifth port coupled to a coolant supply pump, and a valve plate disposed within the valve housing and including at least three layers to open and close the first port, the second port, the third port, the fourth port, and the fifth port.

A tee union ball drain valve member utilizes a first valve member and a second valve member. The first valve member is positioned at the intersection of the third passageway of the valve body and the drain path. The second valve member is located in the drain path. The valve body is coupled to a tee union. The first valve member and second valve member permit draining of the valve body.

Described herein are systems and devices for controlling and monitoring liquid applications of agricultural fields. In one embodiment, a flow device for controlling flow during an agricultural operation includes an offset ball valve having multiple openings that rotate in position to control flow of a liquid through the offset ball valve to an outlet passage. The flow device also includes a first passage that provides a first flow path from an inlet to at least one opening of the offset ball valve and second passage that provides a second flow path from the inlet to at least one opening of the offset ball valve.

A control valve according to the present invention is configured such that when a third opening part, which is an auxiliary opening part, and a third discharge opening, which is an auxiliary connection opening, do not overlap, the third opening part and a continuous discharge opening overlap. Thus, for example, when a flow rate of cooling water for continuous circulation is required, such as during a cold start, cooling water guided through an internal passage is discharged via the continuous discharge opening in addition to cooling water guided from a bypass passage, thereby ensuring a sufficient flow rate of cooling water for continuous circulation.

A three-way water valve (100), comprising a valve seat (10), a valve core (20) provided in the valve seat (10), and a valve bonnet (30) covering the valve seat (10). An actuator (40) is fixed on the valve bonnet (30), and the actuator (40) can drive the valve core (20) to rotate in the valve seat (10); a rotating shaft (41) is rotatably connected to a driving portion (42) of the actuator (40), one end of the rotating shaft (41) is connected to the valve core (20) as a whole, and the driving portion (42) can circumferentially limit the rotating shaft (41).

A rotary valve seal for a coolant control valve is provided that offers improved sealing with a rotary valve body. The rotary valve seal includes a central axis, a cylindrical seal body, and a seal skeleton. The cylindrical seal body has a first stiffness and a first end that is configured with a radially outwardly extending flange. The seal skeleton, having a second stiffness and embedded within the cylindrical seal body, has a plurality of fingers circumferentially arranged within the flange. The second stiffness can be greater than the first stiffness. The plurality of fingers and flange can define alternating stiffness zones. The first end of the seal body and the flange define a bottom surface configured for sealing engagement with a rotary valve body. The rotary valve body can be shaped in the form of at least one spherical segment.
