Characteristics of valves for BF System

• Complete types and specifications with high cost performance and applied system including hot blast stove, furnace top, waste heat recovery, gas de-dusting;
• Meet the process requirements of the BF with high blast temperature of 1450℃， blast pressure of 0.6Mpa and productivity of 3-4ton/day/m³；
• The metallurgy valves with 26 independent intellectual property rights have accurate on/off control, good airtight and longer service life;
• Adopting more than 15 new technology of design, the hot blast valve can resist high temperature and has a good airtight, smooth operation, long service life, energy and water saving;

• Utilization of complete set can guarantee the reliability and low downtime rate of the system, which has greatly reduced the cost of equipment maintenance.
