009930-2 Paser 3 Metering Valve Assembly

The following is a brief description of the functions and uses of the Waterjet Paser 3 009930-2 Metering Valve Assembly. This information is based on the common functions and roles of three-way metering valves (metering valves) in general fluid/waterjet systems, as well as the potential positioning of this assembly within the Paser series.

Basic Functions of the 009930-2 Metering Valve Assembly

Purpose of the 009930-2 Metering Valve Assembly: This three-way (or three-stage) metering valve precisely controls the volume and flow of abrasive entering the waterjet. Precise control of the valve core's displacement and opening/closing timing allows for fine-tuning of the nozzle's abrasive output.

Flow and Pressure Control: By adjusting the valve opening, the abrasive volume can be varied while maintaining a stable system pressure, thereby adapting to varying cutting intensities and materials. Main Functions of the 009930-2 Metering Valve Assembly

Improving Processing Accuracy: Through precise metering control, the water volume and pulse duration of each jet are aligned, improving cutting consistency and surface quality.

Enabling Pulsed Machining: In waterjet machining, pulse control is crucial for cutting efficiency and heat-affected zone management. Metering valves can be used in conjunction with pulse frequency and single-shot volume control to achieve more stable pulse machining.

Material Adaptability: For different materials (such as metal, stone, and ceramic), adjusting jet volume and timing can optimize cutting parameters and reduce flash and cracks.

Relationship of the 009930-2 Metering Valve Assembly to the System

Cooperation with the High-Pressure Pump/Booster System: The metering valve is typically connected to the inlet of the high-pressure system or at the front end of the nozzle. By coordinating with the high-pressure pump pressure, it ensures a stable water column output.

Coupling with the Control Unit: Paser series metering valves typically require precise control by a CNC system (PLC/servo control), receiving set parameters (such as volume, open time, pulse interval, etc.) from the machining program. Coupling with Cooling/Lubrication/Auxiliary Media: In some designs, metering valves may also operate in conjunction with auxiliary media (such as abrasive flow, gas assist, etc.) to achieve a mixed jet or enhance the cutting effect.

Typical Applications of the 009930-2 Metering Valve Assembly

Precision thin-sheet cutting, pre-grinding, material removal in mold processing, and high-precision cutting of complex contours.

Applications requiring high repeatability and controllable pulse characteristics, especially those with high surface quality requirements.

Maintenance and Precautions for the 009930-2 Metering Valve Assembly

Corrosive materials and seal durability in drinking water or desalinated water systems: Seals and valve cores should be regularly inspected for wear to prevent leaks and pressure fluctuations.

Cleaning and Anti-clogging: Mineral deposits or particles in the water path can easily cause blockage inside the valve body. Regular cleaning or the use of a qualified filter is recommended.

Specification Matching: Ensure that control system parameters are consistent with valve body specifications (such as valve core travel, maximum operating pressure, opening and closing time, etc.) to avoid overload or miscontrol. Recommendations for obtaining more specific information:

Consult the product manual for the specific technical specifications (maximum operating pressure, flow range, valve plug diameter, response time, materials, seal type, etc.) for the model 009930-2 Metering Valve Assembly.

Contact the supplier/manufacturer's technical support to confirm the interface, electrical/vapor interface, and control signal protocol (analog, PWM, digital communication, etc.) for the 009930-2 Metering Valve Assembly in your system.
