I know this is a PLC site but it seems that many of you here have been in the industry a lot longer than I.
We have a pneumatically controlled 3" 1/4 spirax valve with a spirax bva200 series controller as the main supply control for 60psi steam. We've ruled out venting being an issue, but the valve doesn't close properly. We swapped out the vlave for a new one and it worked well for about a week and a half and then the same issue started again. We then swapped the pneumatic controller and the same result......
Any ideas?
