A tub and shower diverter assembly includes a manifold sub-assembly that is configured to be detachably coupled to, and in fluid communication with, an existing waterway connector of a conventional tub and shower diverter system. The manifold sub-assembly includes a manifold, first and second flow control valves coupled to the manifold, and first and second tolerance adjustors adjustably coupled to the first and second flow control valves, respectively. The first flow control valve is configured to provide a flow of water to one of a tub or a shower device. The second flow control valve is configured to provide a flow of water to the other of the tub or the shower device. The first and second tolerance adjustors are each configured to be selectively adjusted to change an axial position of the respective tolerance adjustor relative to a wall adjacent the manifold sub-assembly.

Provided are an installation method and an installation device for a fluid control device capable of improving controllability of a fluid in a pipe by improving positional accuracy of a valve body inserted into a hole formed in a fluid pipe in a housing and decreasing the size, weight, and cost of construction equipment such as an operation valve device or an installation device of a fluid control valve.

A valve body unit is configured to be disengaged from a stem by moving the stem and the valve body unit to a valve seat side in a state where a bonnet is separated from the valve seat, thereby pushing a replacement ring such that the replacement ring moves through the bonnet while decreasing in diameter and then drops down onto a ring dropping portion in the free state, then moving the stem, the valve body unit, and the replacement ring to an opposite side to the valve seat side such that a first surface comes into contact with a second surface and the ring dropping portion comes into contact with the replacement ring, and in this state, moving only the stem to the opposite side to the valve seat side such that the connection formed by a connecting mechanism between the stem connection portion and the stem is released.

A serviceable valve carousel system may include a valve carousel housing having a first port adapter receiver, a valve service port, and a second port adapter receiver. A rotatable valve carousel may be disposed within the valve carousel housing. The rotatable valve carousel may include a valve lumen and a removable valve cap. A first port adapter may be removably attached to the first port adapter receiver and a second port adapter may removably attached to the second port adapter receiver. The first port adapter and the second port adapter may be of a type or kind needed to facilitate connectivity. The rotatable valve carousel may be rotatable between a first state that allows fluid communication between the first port adapter and the second port adapter through a check valve and a second state that allows the worn check valve to be removed and replaced via the valve service port.

An apparatus and method for valve cartridge extraction from a valve assembly, wherein the assembly includes a valve member body, a cartridge, and a valve cartridge extraction (VCE) tool comprising at least one pin disposed on the upper surface of the VCE tool. During cartridge removal, the VCE tool is uncoupled from the valve member body and is coupled to the cartridge with the at least one pin. The cartridge is rotated with the coupled VCE tool to assist in cartridge removal. The valve assembly may also include a hood covering the VCE tool.

A valve cartridge for a sanitary fitting having a cartridge housing, a valve stem which is rotatable about an axis of rotation relative to the cartridge housing, a handle for rotating the valve stem, a passage disk with a first passage and a second passage, a control disk rotatable with the valve stem for controlling a liquid flow through the first passage or the second passage of the passage disk, a handle adapter which can be connected to the valve stem for setting a first rotational orientation of the valve stem to the handle in a first position and can be connected to the valve stem for setting a second rotational orientation of the valve stem to the handle in a second position, so that the control of the flow of liquid through the first passage or the second passage can be changed by the control disk.

Provided is a flow rate control apparatus capable of being used continuously when the apparatus is used in equipment that operates continuously, and a flow rate control method for the flow rate control apparatus. A flow rate of a fluid is controlled via any one of control valves disposed in branch passages, respectively. When replacement of the one control valve is determined to be necessary on the basis of a signal outputted from a monitoring portion of the one control valve, the one control valve performing flow rate control is closed, and another control valve disposed in another one of the branch passages, is opened, to perform flow rate control with a flow rate equivalent to that before the replacement. Furthermore, on-off valves disposed at upstream and downstream sides of the closed control valve are closed.
