3" Pneumatic Globe Valve

High-precision 3-inch pneumatic membrane shut-off valve, the valve body structure is single-seated, packing seal sealing form, the pressure class is PN16, nominal diameter range DN80mm, applicable fluid temperature from -60 ~ 450 ℃. Leakage level Ⅵ, flow characteristics for fast open. Balanced valve inner parts, improve the permissible differential pressure of the globe valve.

Feature

• 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: What Should I Do If My Pneumatic Globe Valve Suddenly Doesn't Work?

Pneumatic globe valve suddenly not working can be caused by a variety of reasons. First, check if the air supply is normal and make sure the pneumatic actuator gets enough air pressure. Check whether the air supply connection, pressure regulator and other parts are working properly. Second, check whether the connection between the valve body and the valve cover is tight to prevent air leakage.

If the above is normal, check whether the pneumatic globe valve spool is contaminated or stuck, you can clean the spool and its surrounding. At the same time, check the control system to ensure that the signal transmission is normal. If the problem remains unresolved, it is recommended to seek professional maintenance personnel for overhaul, which may require more in-depth maintenance and troubleshooting to ensure the normal operation of the pneumatic shut-off valve.
