Hartz alloy butterfly valve

Hartz alloy for three-dimensional eccentric butterfly valve metal sealing structure, seal for metal to metal seal, can exchange of metal sealing ring to metal seal, hartz alloy plate with high performance ptfe (graphite) composite plate sealing ring to metal seal. Special seal of this valve system can be guaranteed from ultra-low temperature to ultra high temperature in each temperature range has high sealing performance. Metal to metal surface triple eccentric butterfly valve sealing except as a large pressure swing adsorption (PSA) gas separation device program control valve USES, the wafer butterfly valve hartz alloy can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields, is a good alternative for gate valve, globe valve products.
