USES and features

Marine screw clamping butterfly valve GB/ t3036-94 is suitable for regulating flow rate and stopping medium in water supply and drainage and gas pipeline of ship, medicine, chemical industry, petroleum, electric power, light textile, paper making, etc., and has the function of compensating hot expansion and cold contraction of pipeline.

Its main features are:

Novel design, reasonable, light weight, easy to operate, quick opening and closing;

In addition to the function of regulating and intercepting the flow, Marine helical butterfly valve can compensate the thermal expansion and cold contraction caused by the temperature difference in the pipeline, but also can provide convenience for installation, replacement and maintenance;

The sealing part can be adjusted and replaced, and the sealing performance is reliable.
