DCL electric hard seal butterfly valves are widely used for high pressure, high temperature and high corrosion medium. Engineered with a bi-directional zero leakage seat with an emphasis on low operating torque, this high performance valve is ideal for many projects. So the hard seal valves are commonly used for steam, gas supply, oil, acid and alkali environments.
