DBB Ball Valve
The ball valve is designed to replace the complicated connection of multiple valves in traditional pipelines. Reduce the leakage points in the system, quickly realize the discharge and shut down functions. The double-blocking double-discharge ball valve saves installation space to the greatest extent.
Simplified the installation procedure. Reduce the pressure of the piping system. Convenient for instrument cleaning and maintenance, reducing costs. Products are widely used in hydraulic system pipelines in various industries such as electric power, petrochemical, metallurgy, ocean, petroleum, natural gas, gas, pharmaceuticals, etc.

1) Import and export closure, discharge and isolation
2) Fire-resistant structure. After a fire, each leakage part is designed to be flexible graphite packing or stainless steel clamped graphite to meet the fire resistance requirements.
3) The valve stem has an anti-flying structure, which is convenient for online replacement of packing.
4) The valve has a full diameter, which is convenient for pipeline cleaning, has low flow resistance and strong flow capacity.
