American PARKER plug-in valve structure

American PARKER plug-in valve structure

The PARKER plug-in valve assembly consists of a valve core, a valve sleeve, a spring, and a sealing ring. According to different purposes, it can be divided into directional valve components, pressure valve components, and flow valve components. The installation dimensions of three components with the same diameter are the same, but the structural form of the valve core and the diameter of the valve sleeve seat are different. All three components have two main oil ports A and B, and one control port x.

Parker threaded plug valves have a wide range of types to choose from: balance valve MHC. Overflow valves RDH, RAH, XR, RU. Release overflow valve RAH. Differential unloading relief valve RU. Single channel cross relief valve XR. Pressure reducing/relief valve PRH. Sequential valves PDS, SVH. Pressure reducing valve PRS. Logic valve LE3. Flow control valves NV, NVH, FC, FV. Diverter valve FDC. Load locking valves CVH, CV, CPH, CPC. Shuttle valve CSH, CS. Directional control valve DH. Electromagnetic valves DSH, DSL, DS. Proportional pressure control valves EP3A, EP3B, ER2A, ER2B, SERV, DPR. Proportional flow control valves DF, EF4A.

The importance of the universality of the design of Parker plug-in valves and their valve holes lies in mass production. Taking a certain specification of plug-in valve as an example, in order to mass produce, the size of its valve port is uniform. In addition, valves with different functions can use the same specification valve chamber, such as one-way valves, cone valves, flow regulating valves, throttle valves, two position solenoid valves, and so on. If valves of the same specification but different functions cannot use different valve bodies, the processing cost of valve blocks will inevitably increase, and the advantages of Parker plug-in valves will no longer exist.

Parker plug-in valves have a wide range of applications in the field of fluid control functions, including electromagnetic directional valves, one-way valves, relief valves, pressure reducing valves, flow control valves, and sequence valves. The extension of universality in fluid power circuit design and mechanical practicality fully demonstrates the importance of plug-in valves for system designers and users. Due to the universality of its assembly process, valve hole specifications, and interchangeability, the use of Parker plug-in valves * can achieve * design configuration, and also make plug-in valves widely used in various hydraulic machinery.

Small size and low cost

The benefits of mass production for users are already evident before the valve block is assembled at the end of the line. The complete control system designed with Parker plug-in valves can greatly reduce manufacturing time for users; Each component of the control system can undergo independent testing before being assembled into an integrated valve block; The integrated block can undergo overall testing before being sent to the user.

Due to the significant reduction in required components and connected pipelines, it saves users a lot of manufacturing time. Due to the reduction of system pollutants, leakage points, and assembly errors, reliability has significantly improved. The application of Parker plug-in valves has achieved high efficiency and convenience in the system.

Taking the wheel loader as an example, the Parker plug-in valve integrated block is used to replace the power transmission control device that is constantly malfunctioning, difficult to diagnose and maintain. The original control system had over 60 connecting pipes and 19 independent components. There are only 11 fittings and 17 components on the specially designed integrated block used as a substitute. The volume is 12 x 4 x 5 cubic inches, which is 20% of the space occupied by the original system. The characteristics of using Parker plug-in valves are as follows:

Reduce installation time, minimize leakage points, reduce easily contaminated sources, and reduce maintenance time (because plug-in valves can be replaced without removing pipe fittings)

Fully functional and widely applicable

Parker plug-in valves have been widely used in various engineering machinery, material handling machinery, and agricultural machinery. In the often overlooked industrial field, the application of Parker plug-in valves is constantly expanding. Especially in many situations where weight and space are limited, traditional industrial hydraulic valves are powerless, while plug-in valves have shown great potential. In some applications, plug-in valves are a choice to improve productivity and competitiveness

The functions of new Parker plug-in valves are constantly being developed. These new developments will ensure sustainable production efficiency in the future. Past experience has proven that a lack of imagination is a limitation in achieving production efficiency through the use of plug-in valves.
