Water cooled butterfly valve

Water cooled butterfly valve is a special type of butterfly valve used for high-temperature pipelines. It is made of high-quality heat-resistant steel, with water cooling inside the valve plate. It has the characteristics of low water consumption, high temperature resistance, long service life, easy operation and maintenance, and flexible rotation. It can be used in conjunction with various electric actuators to achieve remote control and automatic adjustment and cut-off. It is widely used in ultra-high temperature gas pipelines in metallurgy, chemical industry, building materials, power stations and other industries as a medium flow regulation and cut-off.
