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.
