PVC double union ball valve is a newly invented ball valve product that was developed to meet the requirements of various corrosive pipeline fluids. It features a simple operation method and is extremely sensitive to operating instructions, with nearly no delay in switching, making it conducive to remote control. PTFE seats reinforced with O-rings help to minimize the wear and strain caused by repetitive cycling. True union ends include a unique design that facilitates piping and removal. Due to the lower cost of transportation when compared to other valves used for the same purpose, PVC double union ball valves have grown popular worldwide.
