Do you know the common classifications of electric butterfly valves? Electric butterfly valve belongs to a variety of electric valve and electric regulating valve. Electric butterfly valve connection methods mainly include: flange type and wafer type; electric butterfly valve sealing methods mainly include: rubber seal and metal seal.
The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as a shut-off valve, control valve and check valve for piping systems. Taking advantage of the manual control device, once there is a power supply defect, it can be temporarily operated manually without affecting the operation.
The soft seal seal pair is composed of non-metallic soft materials to non-metallic soft materials. The sealing pair is composed of metal hard materials and non-metal soft materials. Metal hard seal electric butterfly valve. The sealing pair is composed of metal hard materials to metal hard materials.
Compulsory sealing according to the sealing method: elastic sealing electric butterfly valve. When the sealing specific pressure is closed by the electric valve, the valve plate kneads the valve seat, and the elasticity of the valve seat or the valve plate occurs. The torque is applied to seal the electric butterfly valve, and the sealing specific pressure is generated by the torque applied to the valve shaft. Pressure-charged and sealed electric butterfly valve: The sealing specific pressure is generated by the pressure of the elastic sealing element on the valve seat or valve plate. Active sealing electric butterfly valve: The sealing specific pressure is actively generated by the medium pressure.
