Hot-blast valve
Hot-blast valve is designed to shutoff the furnace stove from the hot blast air duct when the stove is operating in the “heating” mode or is completely shutoff from the furnace. The valve is installed on horizontal section of air main near the stove. The valve may be used as a shutoff valve.
The hot-blast valve is produced in two models:
- «W» - with water cooling;
- «E» - with evaporation cooling.
Main advantages of the hot-blast valve:
- middle part of the housing, welded rings and plate housing are made as one-piece of low-alloyed steel that allows to increase the thermal stability of these details by 2-3 times;
- lower part of the plate has got high-temperature protective coating that is 0,5 -1 mm thick;
- possible to supply with hydraulic or electric drive.
Main design features of the hot-blast valve:
- welded joints are protected with refractory lining;
- increased rigidity of housing and cover;
- increased thickness of the rings lining;
- interchangeability of the main units; high-temperature ramming of carbon threads that allows to increase the service life without changing of sealing up to over 12 months.
Manufacturing period: 120 days.
