A high pressure valve includes a valve body having a surface defining a corresponding portion of a conduit and a pocket. A removable insert is removably inserted into the pocket of the valve body and has surface defining a corresponding portion of the conduit. A seal insert is spaced from the valve body by the removable insert and has an interface with the removable insert. A moving member interfaces with the seal insert for selectively closing the conduit, the interface between the seal insert and the removable insert allows play between the seal insert and the removable insert in response to movement of the moving member.

A plumbing component includes a cold water inlet; a hot water inlet; an outlet configured to output cold water, hot water, or a mixture thereof; a flow shut-off mechanism for restricting the flow of water out of the outlet; a first flow control valve for controlling the flow of cold water; and a second flow control valve for controlling the flow of hot water. Each of the flow control valves comprises a valve member and an associated valve seat, each valve member arranged to engage with the associated valve seat to control the flow of water through the flow control valves to the water outlet. One or both of the valve members includes a graduated flow control bead arranged to seal against the associated valve seat to provide a graduated flow transition between a maximum flow state and a minimum flow state of the, or each, control valve.

A valve with a valve upper plate defining an inlet, a valve body defining an outlet, and a fluid passage. A closure member is disposed in the fluid passage between the inlet and the outlet and has a convex sealing surface and is rotatable between a closed position in which the closure member extends across the fluid passage with the convex sealing surface oriented towards the inlet and an open position in which fluid is able to flow through the fluid passage from the inlet to the outlet. A resilient sealing ring, when the closure member is in the closed position, is moveable between a first configuration in which the sealing ring forms a seal around a circumference of the convex sealing surface and a second configuration in which the valve comprises a circumferential gap between the convex sealing surface and the sealing ring.

A low-volume non-rising stem gate valve comprising a hollow stem, planetary roller screw and anti-rotation rods. The anti-rotation rods isolate the torque force and maintain the alignment of the planetary roller screw with the stem and the screw shaft, thus reducing the amount of material necessary to support ordinary operational forces.

A device for controlling a flow rate and expanding a refrigerant in a refrigerant circuit of an air conditioning system of a motor vehicle. The device has a housing, an actuating element and a valve element arranged in the interior of the housing and aligned in an axial direction, a valve seat element, and at least one sealing element. The valve element is arranged within the valve seat element and sealed towards the housing and the valve seat element via the at least one sealing element, and is formed in a circular cylindrical shape with a sealing area formed on a lateral surface. The inner surface of the sealing element forms a sealing seat in conjunction with the sealing area of the valve element.

A diverter valve for fluid circulation circuits comprising a valve body provided with ports for the passage of the fluid, a pin slidingly mounted inside said body and at least one shutter combined with said pin so that to be able to slide and comprising a deformable element. A first and a second end portion of the valve body are combined with a first and a second fixed element arranged so that the first fixed element causes the compression of the deformable element following the sliding of the pin in a first direction, making it expand radially to define a fluid seal with the valve body in a first position, and the second fixed element causes the compression of the deformable element following the sliding of the pin in a second direction, making it expand radially to define a fluid seal with the valve body in a second position.

A valve with a valve upper plate defining an inlet, a valve body defining an outlet, and a fluid passage. A closure member is disposed in the fluid passage between the inlet and the outlet and has a convex sealing surface and is rotatable between a closed position in which the closure member extends across the fluid passage with the convex sealing surface oriented towards the inlet and an open position in which fluid is able to flow through the fluid passage from the inlet to the outlet. A resilient sealing ring, when the closure member is in the closed position, is moveable between a first configuration in which the sealing ring forms a seal around a circumference of the convex sealing surface and a second configuration in which the valve comprises a circumferential gap between the convex sealing surface and the sealing ring.

A high pressure valve includes a valve body having a surface defining a corresponding portion of a conduit and a pocket. A removable insert is removably inserted into the pocket of the valve body and has surface defining a corresponding portion of the conduit. A seal insert is spaced from the valve body by the removable insert and has an interface with the removable insert. A moving member interfaces with the seal insert for selectively closing the conduit, the interface between the seal insert and the removable insert allows play between the seal insert and the removable insert in response to movement of the moving member.

A water control valve with offset valve core has a main body with a flowing slot, the circumferential wall of which is formed with a water inlet and outlet. An offset rotary valve core is configured offset inside the flowing slot and has a rotary shaft and a water stopping seat. The face of the water stopping seat faces the circumferential wall and has a sealing ring. When the water stopping seat rotates along with the offset rotary valve core and is aligned with the inlet, the sealing ring is pressed against the circumferential wall to close the inlet, thus forming the water stop mode. The rotary shaft and the circumferential wall of the flowing slot define a flowing space. The flow from the inlet must pass through the flowing space and exit through the outlet. A dialing component is used to connect and drive offset rotary valve core.

An example method includes moving a first portion of a control element and a second portion of the control element coupled to the first portion from a closed position to an intermediate position. In the closed position, the first portion being seated against a first valve seat thereby preventing flow through a first orifice and the second portion being seated against a second valve seat thereby preventing flow through a second orifice. In the intermediate position, flow through the first orifice is deterred and flow through the second orifice is permitted. The method includes moving the first portion and the second portion from the intermediate position to an open position. In the open position, the first portion being spaced from the first valve seat thereby permitting flow through the first orifice and the second portion being spaced from the second valve seat thereby permitting flow through the second orifice.
