| Structure： |
The valve seat is composed of a high performance anti-pressure explosion (AED) elastomer sealing ring and a ball in the metal base to form a sealing pair, and a double sealing pair composed of an external surface coating and a ball body. The valve seat is equipped with a metal elastic gasket to limit and fix the position. |
| Characteristic： |
