Midline Butterfly Valve

Midline Butterfly Valve

Midline butterfly valves are the valves which are different from the following developed eccentric butterfly valves. From the definition, there are no angles between the valve seat and disc and others of the midline butterfly valve. As a result, the abrasion is one of the major unpleasant factors among the operation of the midline butterfly valves. Even though the various eccentric butterfly valves have provided a lot of benefits, the midline butterfly valves are continuing making contributions.

Midline butterfly valves are applicable media such as the fresh water, sewage, sea water, foods, various oils, steam, gas, acids, alkali and such others. And they can be driven by various modes, including the worm gear, electrical and pneumatic actuator or manually operated mode. Moreover, the blooming of the midline butterfly valves mainly results from the favorable features.

In most cases, the midline butterfly valves are compact in structure, light in weight and easy for assembly, disassembly and maintenance. Besides, the small operating torque favors the efficiency. And it is small in flowing resistance and good in energy-saving effect resulting from the approximately inclined straight line. Moreover, a wide range of materials are applied to manufacture the midline butterfly valves. And the sealing is enabled to ensure the good performance.
