Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of directional valve ball in China. If you're going to wholesale cheap directional 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 directional valve ball is the core component of the three-way/four-way directional ball valve. Through the special flow channel design on the ball, it enables the switching of the medium's flow direction in the pipeline, and can perform directional functions such as "one inlet and two outlets" and "two inlets and one outlet". The product uses forging + precision machining processes, with the flow channel and sealing surface precisely matched, ensuring sealing reliability and low operating torque during directional switching, and is widely used in chemical, HVAC, water treatment and other working conditions that require medium flow direction switching.
