Description

Transformer ball valve is a fluid control device made of 304/316 stainless steel(or Brass) through precision machining. It uses the spherical valve core to rotate 90° to achieve the opening and closing of the pipeline and flow regulation. It has the characteristics of corrosion resistance, high pressure resistance and long life.

Raw materials: We provide stainless steel / brass ball valves
