| product name: | Stainless steel gate valve flange gate valve |
| Product number: | Z41W |
| Features: | Gate valve, also known as gate valve or gate valve, is the most widely used valve. It controls the opening and closing of the valve through the lifting of the gate. The gate is perpendicular to the direction of the fluid. The size of the passage can be changed by changing the relative position between the gate and the valve seat. |
Stainless steel gate valve application specification:
1. Design and manufacture according to GB12234-89
2. The length of the structure is in accordance with GB12221-89
3. Flange size according to JB/T79-94
4. Valve inspection and test are in accordance with GB13927
