A rotary valve is provided including a housing with an inner chamber having a first inlet, a first outlet, a second inlet, and a second outlet. A valve body is rotatably positioned in the housing. The valve body includes at least one isolated fluid pathway that, depending upon a rotational position of the valve body, provides at least one of a direct connection of one or more of the inlets to one or more of the outlets, or permits flow from at least an other one of the inlets or the outlets that are not in the direct connection created by the at least one isolated fluid pathway into or from the inner chamber. At least one actuator controls the position of the valve body.

A fluid valve comprises a valve housing having at least one fluid inlet and at least one fluid outlet and having a valve axis. At least one of the inlet and outlet is arranged in a wall extending circumferentially about the valve axis. The valve further comprises a rotary valve body arranged within the valve housing for rotation about the valve axis. The rotary valve body comprises a frusto-conical valve body wall and at least one inlet or outlet valve body opening through the valve body wall, the valve body being rotatable about the valve axis so as selectively to place the valve housing inlet and valve housing outlet into fluid communication via the at least one valve body opening. The at least one inlet or outlet valve body opening is a slot which extends in the direction of the valve axis.

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 rotary valve is provided including a housing with an inner chamber having a first inlet, a first outlet, a second inlet, and a second outlet. A valve body is rotatably positioned in the housing. The valve body includes at least one isolated fluid pathway that, depending upon a rotational position of the valve body, provides at least one of a direct connection of one or more of the inlets to one or more of the outlets, or permits flow from at least an other one of the inlets or the outlets that are not in the direct connection created by the at least one isolated fluid pathway into or from the inner chamber. At least one actuator controls the position of the valve body.

A sprinkler system to control distribution of water flow to a plurality of sprinkler heads, the heads providing an outlet to dispense water passing through a corresponding one of the plurality of sprinkler heads and a plurality of distribution control devices, one of the plurality of distribution control devices coupled to a corresponding one of the plurality of sprinkler heads, wherein the distribution control device controls water flow to an associated sprinkler heads for a first predetermined period of time when a flow of water through the distribution control device is detected.

A valve upper part, in particular for sanitary fittings, includes a sleeve-type head piece, which can be fastened in a valve housing of a fitting and through the center of which a spindle extends, which has a handle connection and is mounted for rotation about the longitudinal axis of the spindle and by which a valve body can be actuated, a groove being formed in the spindle, which groove receives an elastic sliding bush, which radially surrounds at least some regions of the spindle and which lies against at least some regions of the inner lateral surface of the head piece.

A method of controlling the flow of different flow paths of fluid is provided. The method includes rotating a valve to a first position, receiving a first concentrate in the first position, discharging the first concentrate through one of two outlets, rotating the valve to a second position, receiving a second concentrate in the second position, and discharging the second concentrate through one of the two outlets.

Gas flow control valves comprising a valve housing including a cylindrical interior passage, and a housing opening extending from the interior passage through the housing. The gas flow control valve further comprises a cylindrical rotary valve element including a sidewall, and a rotary valve element opening extending through the sidewall. The valve element is rotatably received within the interior passage of the valve housing, such that the housing opening may be selectively aligned with the rotary valve element opening, and an area of overlap of the housing opening and the valve element opening may be varied by rotating the valve element within the interior passage of the valve housing.

A testing cap for a valve body includes a base configured to releasably attach to the valve body and to cover an opening in the valve body. The opening is configured to receive a valve cartridge and the base covers the opening in place of the valve cartridge. The testing cap includes a structure extending from the base. The structure is configured to be oriented relative to the valve body in a first orientation and a second orientation. The structure allows fluid to enter the valve body through an inlet port in the valve body and exit the valve body through an outlet port in the valve body when the structure is oriented in the first orientation. The structure covers at least one of the inlet port and the outlet port when the structure is oriented in the second orientation, thereby preventing fluid flow through the valve body.

A steering valve includes a housing and a spool disposed inside the housing. The housing includes a top plane and a bottom plane, the top plane including an opening of a first port and the bottom plane including an opening of a second port. The spool includes a top plane including a first and second opening corresponding to a third port and a fourth port, one of which is configured to align with the opening of the first port depending on the orientation of the housing. The spool also includes a bottom plane including a first and second opening corresponding to the third port and fourth port, one of which is configured to align with the opening of the second port depending on the orientation of the housing. The housing is configured to rotate around the spool and wherein the orientation of the housing determines whether the first port is fluidly coupled to the third port via the first opening in the top plane of the spool while the second port is fluidly coupled to the fourth port via the first opening on the bottom plane of the spool or whether the second port is fluidly coupled to the third port via the second opening in the top plane of the spool while the first port is fluidly coupled to the fourth port via the second opening on the bottom plane of the spool.
