Marine central worm gear butterfly valve GB / T3036-1994

Purpose and characteristics

Marine central wafer worm gear butterfly valve GB / T3036-1994 is suitable for water supply and drainage, gas pipelines such as ships, medicine, chemical industry, petroleum, electric power, light textile, paper making, etc., to adjust the flow rate and intercept the medium, and it can compensate the thermal expansion of the pipeline. Cold shrink function.

Its main features are:
novel design, reasonable, unique structure, light weight, easy operation, and quick opening and closing; in
addition to the function of adjusting and shutting off, the central wafer type worm gear butterfly valve can compensate for the thermal expansion and contraction caused by the temperature difference of the pipeline It can also provide convenience for installation, replacement and maintenance; the
sealing parts can be adjusted and replaced, and the sealing performance is reliable.
