    摘要： The electrically operated valve device (10) comprises: - a supporting body (12) having a valve seat; - a shutter (16) which can be moved in a guided way between a first valve seat opening position and a second valve seat closing position; - a sliding member (18) which is mounted movably on the supporting body (12), is fixed mechanically to the shutter (16), and is movable between an opening condition and a closing condition, in which it moves the shutter (16) to the opening and closing position respectively; - a resilient return member (24) associated kinematically with the sliding member (18) and tending to retain the sliding member (18) in the closing condition; - first opening actuators (50) which arc associated with the sliding member (18) and which arc designed to enter an activated condition, in which they bring the sliding member (18) into the opening condition against the action of the resilient return member (24); - a retaining mechanism (28) mounted on the supporting body (12) and capable of retaining the sliding member (18) when the latter is in the opening condition; and - second closing actuators (52) which are associated with the retaining mechanism (28), which can be electrically activated, and which can assume an activated condition in which they release the sliding member (18) from the retaining mechanism (28), allowing this sliding member (18) to return from the opening position to the closing position.

    摘要： A solenoid operated modular valve includes a solenoid body having a coil and a pole piece positioned in the solenoid body. A valve body cartridge is connected to the solenoid body. A polymeric snap-in seat assembly includes first and second deflectable claw arms each having a barb engaging the valve body cartridge retaining the snap-in seat assembly in direct contact with the valve body cartridge. A seat engagement face when contacted by a valve seal member defines a valve closed position, and is displaced away from the seat engagement face in a valve open position when the coil is energized. A valve body cartridge body end portion includes a barb engagement face having pitched contact edges each having a continuous pitch directly contacted by the barb of the first and second deflectable claw arms to rotatably and frictionally lock the snap-in seat assembly to the valve body cartridge.

    摘要： A fuel filtration system and methods controlling, and operating a fuel filtration system. A first fuel filter head is fluidly coupled to one or more first fuel filters, a second fuel filter head is fluidly coupled to one or more second fuel filters and a selector valve is coupled to the first fuel filter head and the second fuel filter head. The selector valve includes a primary valve inlet port, a primary valve outlet port, and a movable valve body movable from a first position to a second position. The first position fluidly couples the first fuel filter head to the primary valve outlet port and fluidly decouples the second fuel filter head from the primary valve outlet port. The second position fluidly couples the second fuel filter head to the primary valve outlet port and fluidly decouples the first fuel filter head from the primary valve outlet port.

    摘要： The invention relates to an actuator for a valve in a refrigeration system. The invention also relates to a valve with such actuator, and to a refrigeration system with such valve. The actuator comprises an elongated Shape Memory Alloy (SMA) element extending along two or more string-like extensions from a distant end to a proximate end in relation to a valve element of a valve. The SMA element, when forming part of the valve, may extend from the distant end to the proximate end connected to a housing of the SMA element, however, electrically insulated from the housing. An encapsulation may provide a thermal resistance, a thermal conductor and/or an electrical resistance between the SMA element and other elements or the surroundings of the SMA element.
