Description
The double-seal structure of ZZJG VALVE Dual Expanding Plug Valve is not merely embodied in its double-disc design. More crucially, each disc’s sealing surface integrates both soft and hard sealing configurations, with the precision of the hard seal meeting or exceeding Class 4 standards. This dual-seal design not only guarantees zero leakage of the valve but also endows it with reliable fire-safe performance.
The superior sealing performance of ZZJG VALVE Dual Expanding Plug Valve effectively maintains the stable operation of connected pumps and eliminates the risk of air-lock induced flow interruption—a performance advantage repeatedly verified by our global customers.
