TD341W worm drive ventilation butterfly pneumatic valve (1)

product name: TDW worm drive ventilation butterfly type pneumatic valve: TDW caliber: ~ pressure: mm. ~。 MPa material: cast steel, stainless steel TDW worm drive ventilation butterfly pneumatic valve main parameters of the nominal pressure ( MPa。 MPa - medium temperature ℃ ~ - ℃ strength test. MPa applicable media cold and hot medium velocity m/s wind, flue gas leakage rate % TDW worm gear main ventilation butterfly pneumatic valve parts material parts name: pneumatic valve pneumatic valve plate pneumatic valve shaft material: carbon steel carbon steel, stainless steel is made of steel plate welding, a short structure size, light weight, easy installation, etc. The pneumatic valve drive torque is small, easy, easy to operate. Pneumatic valve set on the oil seal ring, no visible gap between seal, leakage rate is small. Valve body between the butterfly plate and pneumatic expansion gap is big, can effectively prevent card deaths caused by heat from the cold. The pneumatic valve can be equipped with a variety of device drivers, such as manual gear, worm gear drive, pneumatic device and electric device. Ventilation butterfly pneumatic valve is widely used in metallurgy, division, electricity, building materials, mining and other industrial pipelines, on medium gas gas control or adjustment.
