Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of valve ball with handle in China. If you're going to wholesale cheap valve ball with handle made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Basic Introduction
The valve ball with a stem integrates the ball and the valve stem (handle) into one piece or firmly connects them through a key / flat structure, which can completely eliminate the connection gap and loosening risk between the ball and the valve stem, efficiently transmit the operating torque, and ensure the accuracy of the switching position. Its structure has extremely high reliability, can withstand connection failure under vibration and impact conditions, is suitable for fluid control scenarios involving frequent operation, automated control, and vibration conditions, and is widely used in industrial automation production lines, chemical plants, and valve systems requiring precise torque transmission.
