摘要： A preventative stop valve system for a wheeled trailer carrying hydraulic equipment is disclosed comprising a stop valve fitted for insertion in-line into the hydraulic line servicing the trailer equipment; the stop valve comprising a reciprocating piston moveable between open and closed positions. The stop valve is connected to the pressurized air line extending to the air brakes of the trailer. Actuation of the stop valve is controlled pneumatically by the setting and release of the air brakes of the trailer by the operator, utilizing conventional controls for the air brakes. A manual override mechanism is further provided for opening the stop valve manually in the event that the hydraulic equipment carried by the trailer must be utilized when pressurized air line to the trailers is disconnected.

摘要： A valve assembly includes a housing defining an aperture, a passageway, and a branch passage. The branch passage extends from the aperture and intersects and communicates with the passageway. The branch passage is disposed at an angle greater than 90 degrees with respect to the passageway. A piston is disposed at least partially within the branch passage and is movable from a first position to a second position. The piston allows communication between the passageway and the aperture when the piston is in the first position, and the piston blocks communication between the passageway and the aperture when the piston is in the second position. An angled seal may be positioned around the piston.

摘要： A slide valve for fluid wherein a slide (3) is axially reciprocally movable in a housing chamber (2) of a valve housing (1). A housing channel (7) in the valve housing (1), which housing channel communicates with a first external connection (8), is provided with a recess (16) directed toward the slide (3) and the piston (3) has a slide channel (14) which communicates with a second external connection (11) via a further recess (15). The slide valve is designed such that passage of fluid does not become blocked by impurities in the fluid, and the slide valve is capable of fine-variability. This is achieved in that the upstream recess (16) has a cross-section which narrows in the direction of the slide valve axis toward the housing channel (7) when the slide (3) is in the closed position. In order to achieve finely variable dosage regulation by the slide valve, the upstream recess (16) has variable cross-section, as the slide (3) is moved in the housing chamber (2).
摘要翻译：一种用于流体的滑阀，其中滑动件（3）在阀壳体（1）的容纳室（2）中可轴向往复运动。在壳体（1）中的与第一外部连接（8）连通的壳体（1）中的壳体通道（7）设置有朝向滑动件（3）的凹部（16），活塞（3）具有滑动通道（14），其经由另一凹部（15）与第二外部连接（11）连通。滑阀被设计成使得流体的通道不会被流体中的杂质堵塞，并且滑阀能够精确地变化。这是因为当滑动件（3）处于关闭位置时，上游凹部（16）具有在滑阀轴线方向上朝向壳体通道（7）变窄的横截面。为了通过滑阀实现精细可变的剂量调节，当滑动件（3）在容纳室（2）中移动时，上游凹部（16）具有可变的横截面。

摘要： A guide frame for a four-way reversing valve is provided. The guide frame includes a frame body. Both ends of the frame body are provided with a connecting portion, respectively. The connecting portion includes a first bending member and a second bending member, and the directions of bending of the first bending member and of the second bending member are opposite. The connecting portion is provided with a reinforcing member. The reinforcing member includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is connected to the outer side of the first bending member by welding, and the second reinforcing plate is connected to the outer side of the second bending member by welding. Optionally, the first reinforcing plate is connected to the inner side of the first bending member by welding and the second reinforcing plate is connected to the inner side of the second bending member by welding. The connection strength of the connecting portion is increased, such that the guide frame is less likely to deform or break.

摘要： A control valve including: a valve body, a flow shutter operatively interposed between an inlet and an outlet, a driving spindle having at least a first actuating end and a second end connected to the flow shutter. The valve also includes a differential pressure automatic regulation device, comprising: a cup-shaped body arranged around the driving spindle and axially mobile with respect to said driving spindle; a spring operatively interposed between the valve body and the cup-shaped body to push the latter away from the flow shutter; a rolling membrane having a radially inner edge fixed to the cup-shaped body and a radially outer edge fixed to the valve body to delimit a first chamber in fluid communication with the inlet and a second chamber in fluid communication with the outlet.
