Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of floating valve ball in China. If you're going to wholesale cheap floating valve ball made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Basic Introduction
The floating valve ball adopts a trunnionless support structure, where the ball is only clamped by the valve stem and seat. It can generate a small axial displacement under the action of the medium pressure, automatically compressing the seat to achieve sealing. With its simple structure, convenient assembly, natural self-sealing characteristics, and low operating torque, it can effectively compensate for machining errors and thermal expansion effects. It is suitable for on-off conditions of clean fluids and weakly corrosive media in medium and low pressure, medium and small caliber applications, and is a commonly used valve ball component for switch control in water supply and drainage, HVAC, food and beverage, and general industrial pipelines.
