FEATURES

The space usage is enough as cylindrical type.
No leakage dangerous as disc moving inside.
The operator safety guarantee.

APPLICABLE PLANT

Thermal power plant.
Cement factory.

BACKGROUND OF DEVELOPMENT

We develop so that it can secure with the problem generation KNIFE GATE VALVE
used in the coal for thermal power plant pulverized(mill) pipe line becomes bigger due to
the generation capacity increase.

Limitation(safety) of operator transit as valve becomes longer.
The ambient space security difficulty with the valve enlarging.
The problem generation including the valve ability, lifetime, and etc.
Coal water leakage danger.
On operation risk due to the disk extrusion which is dangerousness of the
valve, and valve lifetime reduction .
