Tanker Plug Valve

What are Tanker Plug Valves?

A Dairy Tanker Plug Valve is a specially designed valve used in hygienic and sanitary applications to control the flow of liquid products such as milk, cream, juice, or other food-grade materials. It operates using a quarter-turn plug mechanism to provide tight shut-off and unrestricted flow. These valves are commonly installed at the outlet of dairy tankers, process vessels, or transfer pipelines.

Asaid Steel Industries is a leading supplier of Dairy Tanker Plug Valves, delivering precision-engineered valves in stainless steel for maximum hygiene, corrosion resistance, and smooth operation.
