The Calvary DBB Expanding Plug Valve is designed as a high integrity double block and bleed expanding plug valve. These valves are manufactured and tested to API 6D and ANSI B16.34 specifications. This movement assures positive shut-off while reducing wear between the sealing surfaces and extending the life of the valve. The mechanical seal provides a superior valve for demanding applications; including those requiring zero-leakage in Double Block and Bleed service. The valves are designed for easy in line service to be performed through the top entry access.
