A multi-seat bonnet for a valve assembly comprising is disclosed herein. The multi-seat bonnet includes a locking mechanism that is configured to secure the multi-seat bonnet to the valve assembly. Further, the multi-seat bonnet includes a first sealing surface configured to engage a high pressure seat, in addition to a second sealing surface configured to engage a low pressure seat.

A valve manifold includes a manifold and a valve. The manifold has a recess, a first fluid port, and a second fluid port. The valve is disposed entirely within the recess and is fluidically interposed between the first fluid port and the second fluid port. The valve has a rotatable needle having an end that is configured to be displaced relative to a valve seat upon rotation.

A pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. An orifice is disposed between the fluid inlet and the fluid outlet. A valve seat is disposed within the fluid passageway. A movable valve plug is disposed within the fluid passageway, and the valve plug interacts with the valve seat to selectively open or close the fluid passageway. A cage is disposed in the fluid passageway, the cage surrounds the valve plug, and the cage includes a mechanical stop that limits movement of the valve plug within the cage away from the valve seat.

A hydraulic valve includes a valve housing, a valve cone, a spring housing, a check valve, a first hydraulic connection and a second hydraulic connection. The valve housing has a valve seat and the valve cone is movable in the valve housing between a closed position and an open position. In the closed position, the valve cone is in contact with the valve seat and blocks a first flow path between the first and the second hydraulic connection. In the open position, the valve cone is lifted off the valve seat and the first flow path is opened. A spring element is disposed in the spring housing, which biases the valve cone into the closed position. The check valve is disposed in the valve cone and opens a second flow path from the second hydraulic connection to the first hydraulic connection when pressure is applied to the second hydraulic connection.

A valve assembly (6000) for use with a valve body (7000) having a valve seat (7112) is disclosed, the valve assembly (6000) comprising: a cartridge (6200) threadably engaged with and extending away from the valve body (7000); a poppet (6500) slidably engaged with the cartridge (6200); a plate (6600) engaged with the poppet (6500); a plunger (6400) slidably engaged with the cartridge (6200) and slidably extending through the plate (6600); and a retainer (6450) captured between the plate (6600) and a surface of the poppet (6500), wherein the retainer (6450) is threadably engaged with the plunger (6400). The valve assembly (6000) can regulate fluid flow.

A blower unit for pneumatic mixers, comprising: a hollow element internally defining a duct, extending between an input section and an output section, for the passage of an air flow between said sections, wherein said input section can be connected to a source of pressurised air and said output section can be connected to a manifold of a pneumatic mixer; a shutter suitable to shut off said airflow through said output section in a controlled manner; an actuator connected to the shutter and configured to regulate the position of the shutter; the hollow element has a first end portion, at said output section, that can be reversibly coupled to a corresponding end portion of the manifold and wherein the blower unit further comprises first reversible connecting means to establish a reciprocal connection between the end portions.

A valve and adapter for coupling a tubing to the valve. The adapter has first and second adapter end portion with connected fluid passageways. The second adapter end portion being insertable into the free-end portion of the tubing. A valve housing has a first chamber sized to receive the first adapter end portion and a second chamber has inward and outward fluid ports. When the first adapter end portion is positioned within the first chamber, an outer end portion of its fluid passageway is in fluid communication with the inward fluid port of the second chamber. A seal and gripper ring within the first chamber seal with and releasably grip the first adapter end portion. A valve element selectively control fluid flow between the first and second fluid passageways. The adapter may be used with a test cap and other fittings which include a seal and a gripper ring.

Cryogenic valves are disclosed. A valve for includes a valve body, a valve seat, a gland nut coupled to the valve body, and a lower spindle threadably engaged to the valve body. The lower spindle defines a first bore. The valve includes a seat disc mounted to the lower spindle and configured to engage the valve seat in a closed configuration and be disengaged from the valve seat in an open configuration. The valve includes an upper spindle defining a spring bore. A portion of the upper spindle is received in the first bore to matingly engage the upper spindle to the lower spindle such that rotation of the upper spindle causes rotation of the lower spindle. The valve includes a spring that is at least partially disposed in the spring bore of the upper spindle and is configured to bias the upper spindle to sealingly engage the gland nut.

A valve assembly (10) for large scale irrigation including a valve body (20) and a valve head (40). The valve head is adapted to reciprocally travel along a longitudinal axis, supported by a longitudinally aligned shaft (60) inside the valve body. The valve head includes a wall (41) terminating in a peripheral sealing contact surface (42), the wall extending inwardly from the peripheral contacting surface.

A valve body and a control valve including such a valve body, the valve body including an inlet, an outlet, a valve port defined therebetween, and a plurality of discrete flow channels extending between the inlet and the valve port to distribute fluid flow to the valve port in a manner that equalizes the velocity of fluid at the perimeter of the valve port. The plurality of discrete flow channels includes (i) one or more first flow channels arranged to direct a first amount of the fluid flow to a front portion of the valve port, (ii) one or more second flow channels arranged to direct a second amount of the fluid flow to a rear portion of the valve port, and (iii) one or more third flow channels arranged to direct a third amount of the fluid flow to one or both side portions of the valve port.
