2" Pneumatic Globe Valve

High quality 2 inch pneumatic globe valve adopts advanced pneumatic technology to ensure precise control and long service life, single seated conical spool, soft seal + hard seal, max working pressure PN16, with high durability and stability, reliably meets all kinds of fluid pipeline needs.

Specification

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: 2" Pneumatic Globe Valve Troubleshooting

First, check if the air supply is normal, make sure the pneumatic actuator can get enough air pressure. If the air supply is normal, but the actuator does not respond, it may be an internal problem of the pneumatic actuator, and you need to check whether the piston, cylinder and seals of the actuator are intact.

Next, check to see if the connection between the body and bonnet of the 2-inch pneumatic globe valve is tight. If there is looseness or air leakage, you need to retighten the bolts or replace the sealing gasket.

Further, check that the spool is not contaminated or clogged. Contamination may cause the spool to move poorly or the valve may not close completely. Clean the spool and its surrounding parts to ensure that the spool can move freely.

Finally, check the control system to ensure proper signaling. Check that the pneumatic shutoff valve and associated sensors are working properly to rule out the possibility of a faulty control system. Effectively troubleshoot the 2 inch pneumatic globe valve to ensure that it is functioning properly. If the problem is still not solved, it is recommended to seek professional technical support.
