摘要： A valve includes a valve housing having first and second regions, at least one valve chamber configured to be pressurized with air and including an actuating element for opening and closing a valve opening and an actuator for actuating the actuating element, both arranged in the first region. A printed circuit board extends into each valve chamber and to electrically operate the actuator, the printed circuit board(s) being connected to a common main printed circuit board arranged in the second region. Each valve chamber is surrounded by boundary surfaces closing the valve chamber in a substantially gas-tight manner. An open space open to at least two oppositely disposed sides of the valve housing extends between at least two of the valve chambers, and a connecting member of the printed circuit boards extends through connecting openings of the boundary surfaces of adjacent valve chambers and the open space. A sealing material located in the open space encloses the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides. A method of manufacturing such a valve includes manufacturing a conductor element including the printed circuit boards and the main printed circuit board; introducing the conductor element into the valve housing; and filling the open space at least in part with the sealing material from at least one side after the introducing step so that the sealing material seals the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides.

摘要： A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

摘要： A leakage blocking device of a valve is disclosed. When a fluid flowing in a flow path 11 leaks through a gap between the outer circumferential surface of a valve stem bottom (21) and a bottom guide hole (31), a plug 53 of a piston 50 is pushed into a sealing oil chamber 45 by a pressure P1 of the leaked fluid acting on a bottom pressure acting surface S1 of the piston and pressurizes a sealing oil L in the sealing oil chamber 45 to a pressure P2 higher than the pressure P1 of the leaked fluid, thereby blocking leakage of fluid of the valve.

摘要： A valve device for a fuel tank of a motor vehicle includes, for example, a housing having a tank connection for connecting the valve device to a vent line going to or coming from the fuel tank, and a filter connection for connecting the valve device to a vent line going to or coming from an activated charcoal filter. The tank connection and the filter connection are fluidically connected to one another inside the housing through a vent duct. A valve is arranged inside the housing for opening and at least partially closing the vent duct, wherein the valve has a valve element that is movably mounted between an opening position and a closed position inside the housing along a longitudinal axis of the housing. An actuating element is accessible from outside the valve device, which is movably mounted along the longitudinal axis inside the housing and motion-coupled in such a way with the valve element that a movement of the actuating element in a closing direction moves the valve element in closing direction. A valve element return element is configured to move the valve element in an opening direction, and arranged outside the vent duct, between the valve element and the housing.

摘要： An in situ retrofit assembly for a top entry valve includes an annular conduit (100) configured to conform with a seat support (106) at the distal end (207) and a valve body extension (208) with an interior annular region (301). The valve body extension (208) comprises an inlet port (209) fluidically connected to the annular area (301). A gland packing push plate (211) is configured to allow the annular conduit (100) to pass through thereby forming an outlet port (212). This allows the removal of a portion of the fluid from the cold box for downstream processing or manipulation as desired.

摘要： An assembly includes a valve housing and a valve element such as a poppet valve. The valve housing includes a tubular duct and an annular valve seat disposed within the tubular duct. A first flowpath includes an inner bore of the annular valve seat. A second flowpath includes an aperture formed between the annular valve seat and the tubular duct. The poppet valve is configured to engage the annular valve seat and substantially close the first flowpath when the poppet valve is in a first position. The poppet valve is further configured to disengage the annular valve seat and at least partially open the first flowpath when the poppet valve is in a second position.

摘要： A relief valve can include a valve body, a valve member, a valve stem, and a magnetic member. The valve body can define a flow path that extends between a first port and a second port. The valve body can include a valve seat disposed between the first port and the second port. The valve member can be disposed between the valve seat and the second port of the valve body. The valve member can move along an actuation axis. The valve stem can be coupled to the valve member. The valve stem can extend from the valve member towards the first port. The magnetic member can be coupled to the valve member and can generate a magnetic force that urges the valve member to seal with the valve seat of the valve body.
