LM644Y




Anti-wear Slag Discharge Valve

Function and utility
This valve is used to control open and close of dust conveying pipelines installed in thermal power generation, papermaking, steel, coal chemical industries and so on. The valve is particularly useful in high temperature environment such as ash transporting pump of economizer in power plant. Applicable mediums: dry ash and dust.
Working pressure 0.6MPa-1.6MPa, working temperature≤350ºC,air pressure 0.4MPa-0.6MPa
The valve can be installed vertically or horizontally.It is forbidden to install the valve with cylinder facing down.

Performance characteristics

This valve,suitable for ash-handling pipelines,can be used as inlet valve, bleeder valve or balance valve. The valve body is made of nodular cast iron casting. Special treatment has been made for the inside structure of the valve. In order to guarantee the service time and working temperature of the valve, the sealing faces of the gate and the chamber use new cemented carbide material that has high hardness, good toughness and less wear. The gate and the seat have been under fine abrasive machining, so that the valve has no leakage under working pressure.
This valve applies to the size of DN50-DN300
