Product Description

Worm gear groove butterfly valve use:
Worm gear grooved butterfly valve, grooved (clamp) connection valve is a series of new connection valves designed and manufactured by introducing similar advanced products from the United States and Germany, which are widely used in water supply and drainage of fluid pipelines, fire fighting, air conditioning, gas, oil, Pipeline projects such as chemical industry, water treatment, municipal administration, and shipbuilding act as control fluids.

Worm gear groove butterfly valve features:
Worm gear groove butterfly valve has the advantages of fast installation, simple, safe and reliable installation, not restricted by the installation site, convenient for pipeline and valve maintenance, vibration isolation and sound insulation, and overcomes the imitation difference caused by the pipeline connection with different axes within a certain angle range. Solve the characteristics of thermal expansion and contraction caused by temperature difference.
