    2-1/2" pneumatic globe valve is a kind of valve used for fluid control, the diameter is DN65mm. pneumatic actuator is used to realize automatic control, suitable for high pressure environment. Nominal pressure range of 1.6MPa, rated flow coefficient 75KV, operating temperature ≤ 250 ℃. Pneumatic globe valve is widely used in industrial systems to provide reliable fluid regulation and cut-off function.


    • Top-guided construction with multi-spring membrane actuator.
    • Compact structure, light weight, sensitive action, fluid channel is S streamline, small pressure drop loss, large capacity, easy disassembly and installation.
    • 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%.

    Tips: Pneumatic Globe Valve Use Tips

    • Stable Gas Supply: Ensure that the pneumatic shut-off valve gets enough gas supply to ensure normal opening and closing operation of the valve.
    • Valve Operation Status Monitoring: Regularly check the operation status of the valve to ensure that the spool movement is free, no jamming or abnormal sound. If there is any abnormality, carry out maintenance in time.
    • Prevent Overloading: Avoid overloading operation to prevent damage to the pneumatic actuator or valve due to improper operation.
    • Prevent Pollution: Keep the working environment clean, prevent pollutants from entering the valve body, so as not to affect the normal movement of the valve spool.
    • Regular lubrication: Regular lubrication of the key parts of the pneumatic actuator to ensure the long-term reliable operation of the valve.
    • Avoid Freezing: In cold environments, take anti-freezing measures to prevent the pneumatic stop valve from icing and affecting normal use.
    • Pay Attention to Safe Operation: Operators should operate in accordance with relevant regulations to avoid safety accidents.
