Dual Expanding Double Block and Bleed Plug Valve

Bubble-tight fire-safe sealing

The dual expanding plug valves are equipped with two seating surfaces of which each one seals in both flow directions. With the 100% bubble-tight and fire-safe sealing integrity and the ability to double block and bleed within a single valve, the high integrity dual expanding double block and bleed plug valve is an excellent choice for applications that require frequent isolation and testing of gas or liquids. It makes the valve also ideal for loading racks and tank isolation.
