| Top Entry Ball Valve |
 |
The main property:
1.the valves are designed with double slopping surfaces. Functioned by the springs, they automatically adjust the tightness among the valve seats, valve body and ball body to make all of them have excellent tightness under the medium and low pressure.
2. the tightness between the stems, and the contact of the valve cover uses compact among the parking surface stem and cover shoulder surface to reduce the opening moments.
3.the valves are of integral top loading types, so its unnecessary to disassemble them from the pipes. Just remove the cover , you can repair them and change the spare parts to make the maintenance more easy. |
