The invention relates to a changeover valve comprising a spherical valve body, which lies against a first valve seat in a first position and lies against a second valve seat in a second position, wherein an opening is provided in a region between the first valve seat and the second valve seat, which opening is adjoined by a further line, which ends at an outlet connection of the changeover valve, wherein the valve body has a diameter d.sub.Kugel, and wherein at most a circle having a diameter d.sub.einschreib can be inscribed in a projected area defined by an orthogonal projection of the opening onto a selected projection plane, wherein d.sub.einschreib<d.sub.Kugel, and wherein the projected area is noncircular when the diameter d.sub.einschreib of the inscribed circle reaches a maximum in dependence on the selected projection plane.

A mounting assembly is provided for coupling a monitoring device to a valve assembly for relieving vacuum and over pressure conditions in a storage container. The valve assembly includes a body including a first port adapted to be in fluid communication with the storage container and a first valve seat disposed in the body, and a first control assembly including a first valve stem and a first closure element coupled to the first valve stem, the first closure member being movable relative to the first valve seat in response to changes in pressure in the container. The mounting assembly includes a mounting bracket adapted to be coupled to a portion of the body and a mounting tube configured to be slidably coupled to the mounting bracket. The mounting tube is adapted to receive the monitoring device, which is configured to obtain data indicative of the operation of the valve assembly.

A valve device with a built-in orifice is manufacturable with low-cost. The valve body defines an accommodation recess which opens at the surface of the valve body and contains a valve element therein, a primary flow path and a secondary flow path connected to the accommodation recess, the valve element having a sealing portion for blocking direct communication between the primary flow path and the secondary flow path through the accommodation recess, and a through flow passage for making the primary flow path and the secondary flow path communicate through the valve element, wherein an orifice is formed in the through flow passage.

A flush-mounted group for mixing water for a bathroom or kitchen, comprising: a body comprising a valve, designed to be installed in a seat having a given depth with respect a finished surface, a fastening means for fixing the body to the seat, which is adjustable on the body to set the depth at which the body is inset inside the seat, a plate mountable on the finished surface to enclose the body inside the seat and which is provided with an opening for accessing the body, a control member for operating the valve, which is connected to the valve through the opening of the plate. The mixing group comprises a coupling means for connecting together the valve and the control member, which can be adjusted so as to vary a distance between the control member and the valve and ensure correct positioning of the control member inside the opening.

A manifold includes a housing defining first and second inlets and outlets. With the housing, a valve retainer defines a first chamber in fluid communication with the first and second inlets. The valve retainer may engage a first valve assembly having a first actuator attached to a first valve member for regulating flow from the first outlet, and a second valve assembly having a second actuator attached to a second valve member for regulating flow from the second outlet port. A sensor assembly is configured to detect first and second operations of the first and second valve assemblies. A controller directs independent operations of the first and second actuators based on first and second flow rates derived from the first and second operations. The first and second valve members may be positioned within portions of respective first and second valve bodies in open fluid communication with the first chamber.

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 protruding section formed at the one side end of a connector section provided in a valve is inserted into a recessed section formed as part of a valve placement section of a fluid apparatus. The valve is caused to pivot with the inserted portion that serves as a supporting point, and an engaging section formed at the front end of a lever of a hook section formed at the other side end of the connector section is allowed to engage with an engaging protruding section formed as part of the valve placement section of the fluid apparatus. The valve is thus attached to the fluid apparatus.

A new valve assembly is provided that includes an actuator, a housing assembly, and a valve for diverting the flow of liquids through pipelines. Embodiments of the present invention include a yoke with transparent windows, a long valve stem, a bushing nut, an actuator shaft, a jam nut, a stem nut, a union nut to interconnect the valve stem to the actuator output shaft, a position indicator, an indicator plate, and a valve mounting bonnet and lock ring to interconnect the yoke to the valve. The housing assembly includes components to interconnect the actuator output shaft to the valve stem that reduce the side-to-side movement of the actuator output shaft, which in turn reduces the failure rate of the valve assembly.

A fitting (1), at least comprising a housing (2) having a housing wall (3), a mixing cartridge (4), arranged in the housing (2), having a first feed connection (5), a second feed connection (6), a mixing region (7) for mixing a fluid flowing into the mixing region (7) via the feed connections (5, 6), and an outlet connection (8) via which the fluid can flow out of the mixing region (7) and out of the mixing cartridge (4); an actuation unit (9) for actuating the mixing cartridge (4) and a hose (10); the hose (10) being connected to the outlet connection (8) by means of a first end (11) and being arranged in a moveable manner on the housing (2) by means of a second end (12); the hose (10) extending through a channel (13) of the mixing cartridge (4), the mixing region (7) being arranged at least partially between the channel (13) and the housing wall (3).

A three-position booster valve mechanism includes an operating member for moving a supply and exhaust valve. A piston-cylinder control system is provided for moving the operating member between a first position in which the supply and exhaust valve are closed, a second position in which the supply valve is open and the exhaust valve is closed, and a third position in which the supply valve is closed and the exhaust valve is open. A pilot port is provided for moving the operating member in between the first, second and third positions in dependence of a pilot pressure. The piston-cylinder control system connects to the operating member at a central point of application in between the supply and exhaust valve. The operating member extends in opposing directions from the central point of application towards the supply and exhaust valve.
