Forged steel full welded ball valve is mainly suitable for Heating system.citying heat supply,city gas industrial use,petroleum chemical. Applicable medium: Water,air,oil and other fluids,which are not decomposing carbon steel. Forged steel valve compared with other valve products is characterized by high temperature and high pressure, special since the seal design, the higher the pressure, the more reliable seal. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products. Note the amount of fat forged steel valves often ignore. Note grease gun after lubrication, low temperature cut-off valve selection operators valves and greasing connection, on the operations. There are two forged steel gate valve: on the one hand, on the quantity is little greasing, sealing surface due to the lack of lubricant and speed up the wear and tear. On the other hand on the excessive, resulting in waste. Is no categories depending on the type of valve, valve sealing capacity of different calculations. Can work out seal to the valve size and class capacity, then the reasonable injection amount of grease.
