GU series


Vacuum (pressure) ball valve

GU series vacuum (pressure) ball valve is suitable for connecting or cutting off the medium flow in the pipeline in the vacuum system. The valve is a straight-through manual ball valve, which is sealed by a spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed at any position. The applicable working medium is gas or liquid with acid and alkali.
