Ventilated butterfly uses:

Butterfly is a non-ventilated enclosed butterfly valve is widely used in building materials, metallurgy, mining, electricity and other production process on the nominal pressure 0.1Mpa pipeline for connectivity, opening and closing or adjusting medium quality.

Ventilated butterfly's main properties:

Nominal pressure: 0.05 ~ 0.1Mpa Temperature: -10 ~ 300 ℃, -30 ~ 500 ℃, the driving modes: manual, electric, pneumatic, hydraulic, electro hydraulic Medium: flue dust, air, gas and containing dust and gas leakage rate: <3%

Ventilated butterfly structural features:

1, ventilation butterfly valve welded steel plate manufacturing, with short structure size, light weight, easy installation features. The valve drive torque, hoist flexible, easy to operate. Set oil seal retainer on the body, no visible gap between the seal pair, small leakage rate. Expansion gap between the disc and the body is large, can effectively prevent stuck phenomenon caused by thermal expansion and contraction. The valve can be equipped with a variety of drives, such as manual device, worm gear, pneumatic, electric devices.

2, is no link, bolts, etc., reliable, long service life. You can multi-site installation, the flow of influence from the media.
