A valve assembly includes multiple valves operatively connected with a single valve actuator operable to control and restrict the corresponding positions of each of the multiple valves.

There is provided a radiator valve including a pipe, a valve member mounted inside of the pipe for controlling fluid flow through the pipe, a control element exposed on a side of the pipe for controlling the valve member, and a nut with female threads. The pipe includes first and second opposing ends, the first end being a male connector that includes male threads for screwing into a radiator, and the second end retaining the nut with the female threads. There is further provided a radiator including two of the radiator valves, and methods of removing and replacing a radiator core of a radiator.

A valve device includes: a housing having a communication passage forming a part of a path from an inlet to an outlet; and a valve body disposed to be rotatable about a valve axis in the housing. The valve body has a peripheral wall portion facing a communication passage port at one end of the communication passage, and adjusts an opening area of the communication passage port according to its rotation position. The peripheral wall portion has a closure portion capable of fully closing the communication passage port, and openings arranged apart from each other in the circumferential direction. The plurality of openings include a large opening and one or more small openings smaller than the large opening. The centers of the small openings are axially offset.

A housing has a housing main body and an outlet port. The housing main body includes a cylindrical housing inner wall that defines an internal space therein. The outlet port fluidly connects the internal space and an outside of the housing main body to each other. The valve has a valve body rotatable about an rotation axis along a rotation axis of the cylindrical housing inner wall. The valve is configured to selectively open and close the outlet port depending on a rotation position of the valve. The housing inner wall is formed such that a distance between the housing inner wall and the axis of the housing inner wall varies in a circumferential direction.

A seal (1) is provided, in particular for a rotary ball valve fitting (2). The seal (1) has an annular body (4) that is resilient, flexible and provided with a radial lip (4′) and a rigid sealing ring (5) that are made in one piece. A valve, such as a rotary ball valve may include such a seal.

The invention relates to a valve, in particular an expansion valve, for controlling a fluid flow, having a valve housing with an accommodation space and at least two fluid ducts connected to the accommodation space, having an opening which runs perpendicularly to the fluid ducts and opens into the accommodation space, wherein a sealing ring holder with a valve means is situated in the accommodation space, wherein the sealing ring holder with the valve means held therein can be inserted into the accommodation space through the opening, and wherein the valve means is positioned rotatably in the sealing ring holder by means of at least two sealing rings. The invention also relates to a sealing ring holder.

A valve trim includes a body having a plurality of parallel flow passages extending from a first end of the body to a second end of the body, opposite the first end. Each flow passage includes a throat and an expansion chamber and each throat is nested between the expansion chambers of directly adjacent flow passages.

An isolation valve unit with a fusion outlet including a valve body comprised of a metal, such as brass, and having at least two ports, at least one of the ports including an overmolded thermoplastic end surrounding and enclosing the port from which the fusion outlet extends. In one embodiment, the thermoplastic end is composed of a PP-RCT material and is securely formed over the port by way of an over molding technique. The valve unit further includes a ball valve accommodated within the valve body and a handle for actuating the ball valve. The isolation valve unit is configured to couple to a larger polymeric pipe and to control the flow of fluids in a plumbing system via actuation of the ball valve.

A ball valve assembly includes a ball configured to rotate between an open position and a closed position. The ball valve assembly also includes a cradle having a ball-facing surface. The ball-facing surface faces the ball and is positioned at an end of a fluid passage through the cradle. In addition, the cradle is configured to rotatably support the ball to enable the ball to rotate between the open position and the closed position, and the cradle is configured to block movement of the ball toward the ball-facing surface to establish a separation distance between the ball and the ball-facing surface.

Valves having seats and counterseats that can be moved by fluid within the valve. In one embodiment, a valve includes a flow control assembly inside a body. The flow control assembly includes a ball rotatable between an open position and a closed position to control flow, a seat installed on the ball, and a counterseat installed in the body. The seat and the counterseat can move radially with respect to the ball and have mating surfaces that engage and seal against one another when the ball is in the closed position. The flow control assembly allows pressurized fluid in the body to cause net forces on the seat and the counterseat that push the seat and the counterseat toward each other when the ball is in the closed position. Additional valve systems, devices, and methods are also disclosed.
