A water control valve has a valve casing, a valve seat, a fixed valve plate, a movable valve plate, a driving piece, a press structure and a pulling structure, wherein the valve seat is assembled on one end of the valve casing. The fixed valve plate, movable valve plate and driving piece are disposed in the valve casing. A flow channel for the fluid is formed among the valve seat, the fixed valve plate and the movable valve plate. The driving piece is in contact with the movable valve plate. The pulling structure has a first shaft lever and a swing piece. The press structure pulls the first shaft lever the move axially. The first shaft lever pulls the swing piece to rotate, so that the driving piece drives the movable valve plate to slide laterally, the handiness of flow control or the on/off of the flow channel is enhanced.

A regulating device for an exhaust turbocharger, is received in an exhaust gas conducting section of the exhaust turbocharger, with the aid of the regulating device a fluid flow onto a turbine wheel rotatably received in the exhaust gas conducting section can be conditioned, a through-flow opening formed in the exhaust gas conducting section is to be opened and closed with the aid of a valve element of the regulating device, the valve element is arranged on a pivot arm of the regulating device, and wherein the valve element has a sealing surface for avoiding a leak in a closed position of the regulating device. To reduce secondary torques acting upon the valve element during operation, a connection is formed between the pivot arm and the valve element in or at least close to a center of gravity of an effective valve element body of the valve element.

A faucet handle assembly for a Roman tub has a low profile and can be installed from above or below the tub deck. A valve body extends along a longitudinal axis and defines a cartridge cavity. A lower end defines water inlet and outlet passages and a threaded external surface. An upper end defines a threaded internal surface. A mixing cartridge with a rotatable stem and a cartridge spacer are carried in the cavity with the spacer axially between the cartridge and the inlet and outlet passages of the valve body. A fastener has a threaded external surface threaded to the threaded internal surface of the valve body upper end. An upper mounting ring has a hub disposed about the upper end of the valve body and a flange extending radially outwardly from the hub.

A high-velocity low-pressure cooling system (100), especially suited for data center applications, includes an air coolant loop (102), a non-air coolant loop (104) and a cooler unit (126) for heat transfer between the loops (102 and 104). The air loop (102) is used to chill ambient air that is blown across heat transfer surfaces of equipment mounted in data center racks (110). In this manner, effective cooling is provided using a coolant that is benign in data center environments.

A valve includes a bore within a valve body having a central axis. A plurality of galleries in the bore define flow paths for hydraulic fluid. A spool is positioned in the bore, and the spool is moveable along the central axis between a first position in which hydraulic fluid from a central pump gallery is prevented from flowing to first and second working galleries and from flowing to one or more tank galleries; a second position in which hydraulic fluid from the central pump gallery is in fluid communication with both the first and second working galleries simultaneously; and a third position in which the first and second working galleries are in fluid communication with the one or more tank galleries simultaneously.
