💡 What causes steam globe valves to leak past the trim in residential and commercial buildings?
Tracking pressure drops usually wear down the seating interface faster than normal airflow. You need a handy method to keep the stem sealed under constant heating cycles.
- Swap to standard ring pack seal gaskets to stop moisture seepage around the rotating stem
- Run air pressure gradually instead of slamming full line velocity into the bronze seat
- Match the flange rating to your exact pipe schedule so thermal expansion never breaks the housing
