The products are summed up:
The ventilation butterfly's valve of production of our factory adopts the stencil plate to weld and make, has physical dimension to be short, light, it is convenient when the characteristic to install. This valve urges the moment to be small, it is flexible to open and close, easy to operate. Valve body set up oil is it is it enclose to block , seal pair is it can see interval to have , little leakage rate have to seal. Butterfly board and inflation, valve of body interval heavy, can card caused by the fact that heat rises coldly and contracts to prevent the phenomenon has died effectively. This valve can allocate many kinds of drives , such as manual device , worm gear transmission device , pneumatic device , electronic device. Ventilate butterfly's valve and is used for managing such industrial pipeline as the gold , teacher , electricity , building materials , mine ,etc. extensively, control regulating action to the medium gas angrily. |
