Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of hollow valve ball in China. If you're going to wholesale cheap hollow 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 hollow valve ball adopts an internally hollow shell structure. After being forged or cast, the flow passage is machined. On the premise of ensuring structural strength, it significantly reduces the weight of the ball, saves raw materials, and simultaneously reduces the operating torque of the valve. Its hollow design is suitable for large-diameter working conditions, can be paired with floating or fixed valve seat structures to achieve reliable sealing, and is applicable to clean fluid transportation scenarios with medium and low pressure and large diameters. It is widely used in on-off control of water supply and drainage, HVAC, city gas, and long-distance transmission and distribution pipelines.
