DUAL DISCHARGE VALVE DOUBLE BLOCK
Double block and bleed ball valves are designed in order to replace the multiple valves connection complex forms in traditional pipeline.
Reduce the leakage in system to achieve quickly bleed ,close function. Double blocok and bleed ball valves maximum save installation space and Simpliflied installation program.
Cut down the pressure in piping system. Convenient instrument Cleaning maintenance and reduce the costs.
The valves are widely used in ectric power, petroleum chemial industy, metallurgy, Marine, oil, natural gas, coal gas, pharmaceutical and other industies hydraulic system pipeline.
