Brief introduction:
The reduced diameter ball valve has the same performance as the full diameter ball valve, and its characteristic is that it has a much smaller load pressure on the pipeline than the full diameter ball valve. The design of the shrinkage is more conducive to the ball cleaning of the valve passage and saves materials.
Product parameter of the reducing ball valve:
1. Size range: 2"-36"
2. Nominal pressure: 1.6mpa
3. Material: WCB, SS
4.Design and manufacture: GB12237-1989
5.Flange connection: GB9113, JB/T79, HG20592, SH3406
6.Structure length: GB12221-1989
7.Welding standard: GB12224-1989
