TC Ball Valves
What are TC Ball Valves?
A TC Ball Valve is a hygienic, tri-clamp end valve that uses a rotating ball mechanism to start or stop fluid flow in sanitary process lines. It offers easy-to-turn operation and a straight-through, full-bore design that minimizes pressure drop and fluid turbulence. These valves are ideal for applications that require complete flow shut-off, easy cleaning, and resistance to contamination.
Asiad Steel Industries provides premium TC Ball Valves engineered for hygienic applications and efficient flow control.
