Lug Butterfly Valves

According to the different sealing materials, cast steel handle butterfly valves can be divided into two categories: soft seal butterfly valves and hard seal butterfly valves. Soft sealed butterfly valves usually use rubber or other soft materials as sealing materials, while hard sealed butterfly valves use metal materials such as graphite and metal seals. Soft sealed butterfly valves can achieve zero leakage in certain situations, while hard sealed butterfly valves are more suitable for high temperature and high pressure environments. At the same time, it is divided into handle butterfly valve and turbine butterfly valve according to their uses. Handle butterfly valves are manually operated and can be quickly closed and opened, making them easy to operate. Turbine butterfly valve use turbine rotation to control valve opening and closing. According to the valve plate, it can be divided into lug butterfly valve and groove butterfly valve, with one groove end and one pair clamp.
