    With a nominal pressure rating of PN16 MPa, rated flow coefficient of 20 Kv indicates its efficiency in regulating flow rates. In terms of pressure differentials, the valve can handle positive action up to 1.85 MPa and opposite reaction up to 2.47 MPa.


    • By using a thin-film multi-spring actuator connected to the adjusting mechanism by three columns, the overall height can be reduced by about 30 per cent and the weight by about 30 per cent. The overall height can be reduced by about 30 per cent and the weight by about 30 per cent.
    • The valve body is designed according to the principle of fluid dynamics into an equal cross-section low flow resistance flow path, the rated flow coefficient increases by 30%.
    • Compact structure, light weight, sensitive action, fluid channel is S streamline, small pressure drop loss, large capacity, easy disassembly and installation.
    • Top-guided construction with multi-spring membrane actuator.

    Tips: What maintenance procedures are recommended for this valve?

    • Regular Inspection: Conduct routine visual inspections to check for any signs of wear, corrosion, or damage to the valve body, actuator, and other components. Regular inspections help identify potential issues early on.
    • Lubrication: Apply lubrication to moving parts, especially those involved in the actuation mechanism, to reduce friction and ensure smooth operation. Use a suitable lubricant recommended by the manufacturer.
    • Check Seals and Gaskets: Inspect all seals and gaskets for signs of wear, deterioration, or leaks. Replace any damaged or worn seals to maintain the integrity of the valve's sealing system.
    • Verify Valve Position Indicators: Ensure that the valve position indicators, whether visual or electronic, are functioning correctly. This is crucial for operators to have accurate information about the valve's status.
    • Inspect Pneumatic System: Check the pneumatic system for leaks, pressure irregularities, or any issues that may affect the actuation of the valve. Address any pneumatic system problems promptly to maintain reliable valve control.
