A control valve and a control valve system. The control valve comprises a valve body and valve cores; the valve cores comprise a first valve core and a second valve core; the control valve comprises a valve cavity; the valve body has multiple ports; the first valve core and the second valve core are located in the valve cavity; rotation of the valve cores can open or close ports corresponding to fluid channels of the valve cores. The control valve further comprises a first transmission portion and a second transmission portion, the first transmission portion and the first valve core are integrally formed or in transmission connection, and the second transmission portion and the second valve core are integrally formed or in transmission connection; a valve core shaft and the first valve core are in transmission connection.

Device for controlling a flow-through and distributing a fluid in at least one fluid circuit, in particular a refrigerant in a refrigerant circuit including a housing with ports for connecting with fluid lines, each of which is connected via a passage opening with the at least one interior volume of the housing, as well as with at least one valve element disposed in the interior volume of the housing with a drive element for moving the valve element relative to the housing. The at least one valve element is supported rotatably about a rotational axis and comprises at least three through openings developed as through-bores forming in the interior of the valve element a common volume. An axis of symmetry of a first opening and the rotational axis of the valve element are located on a common axis. The device is used in a refrigerant circuit of a thermal system.

Disclosed is a powder protecting three-way valve for a semiconductor or flat panel display manufacturing apparatus, including: a valve casing including an inlet and a plurality of outlets; a rotating ball rotatably installed in the valve casing to control a flow direction of reaction by-product gas; a nitrogen gas supply member which receives nitrogen gas from an outside, guides a flow of the nitrogen gas using a guide path, and supplies the nitrogen gas into the valve casing to prevent a powder contained in the reaction by-product gas from accumulating in the valve casing; and a heating unit installed in the nitrogen gas supply member to heat the nitrogen gas passing through an interior of the nitrogen gas supply member. The nitrogen gas supply member is formed as a thin flat body pressed against one side surface of the valve casing and is integrally coupled to the valve casing.

A flow control valve apparatus is provided in which a main valve adjusts the flow rate of cooling water by operating a plurality of ports and a sub-valve that operates with the main valve adjusts the flow rates of the cooling water circulating through a cylinder block and a cylinder head. The flow rate of the cooling water is variously adjusted based on the operation conditions of a vehicle.

The present subject matter discloses a system and method of winterizing and de-winterizing a structure in order to prevent waterlines from freezing and getting damaged. The system includes electronic valves connected to waterlines i.e., main waterline and drain line. The electronic valves include electronic ball valves. The electronic valves communicatively connect to an electronic device. A user operates the electronic device to winterize and de-winterize the structure. Winterizing includes closing the electronic valve on the main waterline that supplies water into the structure and opening the electronic valve on the drain line causing the water to drain out. De-wintering includes closing the electronic valve on the drain line and opening the electronic valve on the main waterline to supply water back into the structure. Winterizing prevents the waterlines from freezing and getting damaged in cold weather conditions.

A water sediment filter assembly includes a screen member and a drain port which permits the removal of collected debris. The water sediment filter assembly includes a valve member which can be moved to different positions to permit the draining of collected sediment through the drain port.

A water-abrasive suspension cutting facility includes a pressure tank (11) for providing a water-abrasive agent suspension (13) which is under pressure, a lock chamber (21), and a refilling valve for refilling abrasive agent into the pressure tank via the lock chamber (21). The refilling valve (21) includes a valve entry (49), a valve exit (51), a valve space (71) which is arranged between the valve entry (49) and the valve exit (51), and a valve body (67) which is located in the valve space (71). The valve entry (49) is connected to the lock chamber (21) and the valve exit (51) to the pressure tank (11). The refilling valve (19) can assume a first closure position, a first open position and a second open position. In the first closure position the lock chamber (21) is fluid-separated from the pressure tank.

A valve includes a housing, a ball rotatably coupled to the housing, a handle coupled to the ball, a ball retainer coupled to the housing, and a radial seal. The housing includes an inlet, an outlet, a passage between the inlet and the outlet, and a lower housing bore. The ball includes a body, a lower trunnion, and an opening through the body. The handle is operable by a user to rotate the ball in the housing to align the opening with the passage of the housing to open the valve. The ball retainer retains the ball in the housing. The ball retainer includes a threaded portion and a shaft portion in the lower housing bore. The radial seal is between the shaft portion and the lower housing bore.
