Marine spiral wafer butterfly valve GB / T3036-1994

Purpose and characteristics

Marine spiral wafer butterfly valve GB / T3036-94 is applicable to water supply and drainage, gas pipelines such as ships, medicine, chemical industry, petroleum, electric power, light textile, paper making, etc., as the function of adjusting flow and intercepting medium, and it can compensate for thermal expansion and contraction of pipeline Function.

Its main features are:
novel design, reasonable, unique structure, light weight, easy operation, rapid opening and closing; in
addition to the function of adjustment and shutoff, the marine spiral wafer 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.
