Description: VAN BƯỚM ĐẦU KHÍ NÉN
low load butterfly valve adopts the metal face seal design of central line structure. The metal seat surrounds the disc. This structure can reduce the seat leakage. Featured by simple structure, light weight, mature manufacturing technology and convenient maintenance, the butterfly valve is used for flow and pressure control in low pressure service conditions and is suitable for fluids of very high temperature. It is widely used in steel, building materials, petrochemical industry, power station and other industries.
Output Torque 10Nm to 8000 Nm
Control: Double acting,Single acting normally closed, acting,Single normally open
