Coal lock and ash lock valves for pressurized gasification of pulverized coal.
Hydraulic systems have greater power and more reliable performance, but the cost is likely to be high.
Hydraulic systems are better to use, as the valves are larger; to operate them, larger cylinders are required and their movement is relatively slow.
High pressure in hydraulic valves, strong power output; poor working conditions due to coal ash
