Stainless Steel Ball Valve Classification

Jan 18, 2018

 According to the different forms of ball valve connection, can be divided into stainless steel thread ball valve, stainless steel flange ball valve, stainless steel welding ball valve.

According to the different ball valve drive, can be divided into stainless steel manual ball valve, stainless steel electric ball valve, stainless steel pneumatic ball valve.
