Production process
We are manufacture and have own factory and production lines.
 
We test the gate valve one by one
We have a sophisticated casting technology.
The gate valves are tested by 2 times before leaving our factory.
1.The fist time is in the assembly process, and valves are tested one by one.
2.The second time is before packaging, we use the method of spot check, 5%. Once found problems, 100% testing.
3.So we can guarantee 95%~98% zero-leaking.
