A diverter valve for conveying a material has a housing with at least three passage openings for feeding or discharging material. The passage openings define a conveying plane. The diverter valve includes a rotary part with an outer contour that is conical, at least in sections, with respect to its axis of rotation. The rotary part is arranged in a sealed manner in the housing. The rotary part can be axially displaced and rotated within the housing. The axis of rotation is perpendicular to the conveying plane. A passage conduit is arranged in the rotary part, which, depending on the rotational position of the rotary part, connects to each other two passage openings for conveying material along the passage conduit through the diverter valve. A drain opening is provided in the housing for the automatic drainage of a liquid from the housing.

A valve assembly for select distributed discharge of received fluid in a predetermined manner is generally provided. The assembly includes a manifold and a rotatable valve body. The manifold has an internal chamber, a fluid ingress passage for receipt of fluid, and a plurality of fluid discharge conduits. The fluid ingress passage and fluid discharge conduits are in fluid communication with the internal chamber. A first internal chamber section is characterized by the fluid ingress passage with a second internal chamber section characterized by ingress portions of the fluid discharge conduits. The valve body is adapted to be sealingly seated within the internal chamber so as to fluidly isolate the internal chamber sections, and includes a bore axially extending inwardly from a first end thereof for receipt of fluid from the fluid ingress port of the manifold, and a fluid egress passage in fluid communication with the bore for passage of received fluid to a select fluid discharge conduit of the fluid discharge conduits.

A diverter valve for conveying material to be conveyed, the diverter valve being cleanable using a method for CIP cleaning, comprises a housing with at least three passage openings to feed or discharge the material to be conveyed, the passage openings defining a conveying plane. The diverter valve further comprises a rotary part having an axis of rotation and an outer contour designed conically in relation to the axis of rotation at least in sections, the rotary part being arrangeable in the housing in a sealed manner, the rotary part being displaceable along the axis of rotation in an axially driven manner and being arranged such as to be drivable for rotation about the axis of rotation, the axis of rotation being oriented perpendicular to the conveying plane, a passage duct arranged in the rotary part, which—depending on a rotary position of the rotary part—connects in each case two passage openings for conveying material along the passage duct through the diverter valve. The CIP cleaning method of a diverter valve of this type comprises the pulling back and rotating the rotary part into an intermediate position to clean and then dry the diverter valve intensively. A particular feature is the embodiment configured without drainage in the housing of the diverter valve.

A rotary valve includes a valve body including an opening formed therein, a rotary component received within the opening of the valve body with the rotary component configured to rotate relative to the valve body about an axis of rotation thereof, and a sealing assembly including a hard sealing structure and a soft sealing structure disposed between the valve body and the rotary component. The hard sealing structure is formed from a substantially rigid material and is configured to sealingly engage the rotary component. The soft sealing structure is formed from a resiliently deformable material and is configured to sealingly engage the hard sealing structure and the valve body.

A stopcock, comprising a housing element defining a central bore and at least first, second and third ports; and a handle element which is selectably positionable relative to the housing element; at least one of the housing element and the handle element defining: a first fluid flow passageway communicating between two of the at least first, second and third ports; a second fluid flow passageway communicating between at least two of the at least first, second and third ports, and a fluid flow guide associated with the second fluid flow passageway, the fluid flow guide extending radially towards an inner facing wall of the central bore.

A diverter system for directing fluid from an inlet port to a selected outlet port. In one embodiment, a high-pressure fluid and proppant received from a missile can enter a diverter through an inlet port and travel to a well head via a Christmas tree or fracturing stack. The diverter system can have a plug housed in the diverter body that connects to the inlet port. The diverter body has at least one outlet port to which the plug can connect the inlet port. The plug can be configured to connect to one outlet port at a time so that a single wellhead can be singled out to experience a fracturing stage. Once the fracturing stage is complete, another wellhead can be singled out, and the previous well sealed off so that other operations can be performed.

According to a preferred embodiment of the present invention there is provided a stopcock including a housing element defining at least first, second and third ports, a handle element which is selectably positionable relative to the housing element, at least one fluid passageway communicating between at least two of the at least first, second and third ports, the at least one fluid passageway being selectably defined by at least one of the housing element and the handle element, the at least one fluid passageway being configured for enabling flushing an internal volume of at least one of the first, second and third ports by a fluid flow which does not flow entirely through the port whose internal volume is being flushed.

The exhaust gas recirculation (EGR) system provided herein utilizes a crossover (X) valve that is selectively activated at the direction of the electronic control module (ECM) to mix the high temperature (HT) and low temperature (LT) circuits of the EGR system under certain predetermined operating conditions. Thus, HT circuit fluid (at engine temperatures) is selectively fed into the LT circuit fluid (at ambient temperatures) to heat certain LT circuit components that are normally cooled by the LT circuit before starting the low pressure (LP) EGR in certain cold cycles. When this heating is finished, the X valve is closed to provide normal HT circuit/LT circuit fluid separation. The X valve can be controlled using a rotational actuator or the like. To avoid exposing the LT circuit to the high revolution-per-minute (RPM) operating conditions of the HT circuit, a HT bypass mechanism is provided.
