The present disclosure discloses a seal and a regulating valve having the seal. The seal is used for sealing a flow channel between a pipe orifice of a housing and a valve body in the regulating valve. The seal includes an elastic member and an embedded member. The elastic member is ring-shaped, the embedded member is at least partially embedded in the elastic member, and the hardness of the embedded member is greater than that of the elastic member. The seal of the present disclosure has a simple structure, which not only enables miniaturization of the structure of the regulating valve, but also can simplify assembly steps of the regulating valve, thus facilitating assembly automation of the regulating valve.

A fluid control device includes a body having an inlet, an outlet, and a fluid flow path between the inlet and the outlet, a seat, and a control element that is coupled to a stem. The control element and the stem are movable along a first axis and biased toward a closed position in which the control element engages the seat. The fluid control device includes an actuator assembly including a shaft that is operatively coupled to the stem via a Scotch yoke mechanism such that rotation of the shaft in a first rotational direction causes movement of the stem and control element along the first axis in a first translational direction. The actuator assembly includes a trigger mechanism that is responsive to fluid pressure and prevents rotation of the shaft in a first mode of operation and releases the shaft to allow rotation in a second mode of operation.

A seal arrangement for a fluid valve includes: a first seal for sealing abutment against a pivotably adjustable valve body of the fluid valve; a second seal for sealing abutment against a valve housing of the fluid valve; and a separate, elastically deformable intermediate piece arranged between a first wall of the first seal and a second wall of the second seal. The intermediate piece has at least one axial section whose cross section has, in relation to the seal opening, a first, radially outer lateral surface and an opposite, second, radially inner lateral surface, and the radially outer lateral surface is at least sectionally concave, and the radially inner lateral surface is at least sectionally convex.

Coolant valve for a vehicle includes a housing having a plurality of coolant ports, a valve element arranged in an adjustable manner in the housing in order to connect or disconnect coolant ports, and at least one seal arrangement. The seal arrangement bears in a sealing manner against the housing on one side and in a sealing manner against the valve element on the other side, the seal arrangement having a carrier element made of a first material and a sealing element made of a second material, the second material being softer than the first material. The sealing element has a first sealing lip bearing against the valve element and the carrier element having a supporting portion. The first sealing lip protrudes beyond the supporting portion with a free end, and the first sealing lip is pressed against the supporting portion when coolant flows through the coolant valve.

A seal for use in a fluid control valve includes: a first, elastically deformable, plastic part; and a second plastic part configured as a hard seal element and connected to the first plastic part. The first and the second plastic parts form a seal assembly having a first frontal end configured to bear in a sealing manner on an actuatable valve body of the fluid control valve, and a second frontal end configured to bear in a sealing manner on a valve housing of the fluid control valve, wherein at least the first frontal end has a first end side having an encircling projecting bead configured to seal against the actuatable valve body.

A method of sealing a coolant control valve of a cooling system for a power device which generates heat as a by-product of operation. The cooling system includes a pump, a heat exchanger, and coolant. The valve includes: an internal channel in fluid communication with the exchanger; a sealing package in contact a surface of the coolant control valve and bounding a portion of the cooling system and the channel; and a rotary element in the channel and rotatable to open and close the valve. The portion is bounded in part by the valve and the sealing package. The method includes: starting-up the device; creating a pressure differential of at least 0.2 bar between the coolant in the portion of the cooling system, and the coolant in the internal channel; rotating, using a motor, the rotary element; opening the valve; and pumping, using the pump, the coolant through the internal channel.

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 disclosure relates to valve assemblies having a valve body including a first port, a second port and a fluid passageway extending therebetween. A valve member, having a through port, is arranged in the fluid passageway and is moveable between an open and closed positions. A sealing arrangement is arranged between the first port and the valve member and includes a sealing member arranged to seal against the valve member such that fluid cannot flow around an outer surface of the valve member. The sealing arrangement includes a sleeve arranged in the fluid passageway between the first port and the valve member. A deformable, incompressible, medium is contained around the sleeve and arranged such that, in use, a fluid within the sleeve exerts an outward pressure on the sleeve causing the sleeve to deform and act on the medium to push the sealing member against the valve member.

An annular assembly for compressing a seat of a ball-valve, including: a valve body or insert, including an annular internal counter-bore that defines an inner counter-bore diameter; a sleeve inserted into the annular internal counter-bore, defining at least one outer diameter of the sleeve; the body or the insert defining with the sleeve an annular housing in which the assembly includes, in succession: a downstream stack of head rings, an annular head shim, a stack of mechanisms of compression, an annular base shim, and an upstream stack of base rings.

A seal arrangement for use in a fluid control valve includes: a first seal configured to sealingly abut against an actuatable valve body of the fluid control valve; a second seal configured to sealingly abut against a valve housing of the fluid control valve; and an elastically deformable intermediate spacer, arranged between the first seal and the second seal and configured to elastically space the first and second seals apart. At least in an installed state of the seal arrangement in the fluid control valve, the first seal and the second seal are joined to one another in positively locking fashion in an axial direction of the seal arrangement.
