What should I do if the valve is not tightly closed? What are the handling methods

Reasons for general valve failure to close tightly or tightly: (1) There are impurities stuck on the sealing surface, which deposit at the bottom of the valve or cushion between the valve disc and valve seat. (2) Rust on the valve stem thread prevents the valve from rotating; (3) The sealing surface of the valve is damaged, causing leakage of the medium; (4) The poor connection between the valve stem and valve disc causes the valve disc and valve seat to deviate and cannot be tightly contacted.

Sealing instructions for ball valves

The main seat sealing ring material for ball valves is polytetrafluoroethylene (PTFE), which is environmentally friendly to almost all chemicals and has comprehensive characteristics such as low friction coefficient, stable performance, resistance to aging, wide temperature range, and excellent sealing performance. However, the physical properties of polytetrafluoroethylene, including its high coefficient of expansion, sensitivity to cold flow, and poor thermal conductivity, require the design of valve seat seals to revolve around these characteristics.
