A sanitary three-piece flange ball valve is a type of valve specifically designed for sanitary pipes and equipment.
It usually uses high-quality materials and precise manufacturing processes to ensure its excellent performance and reliability during use.
This valve is typically manufactured with stainless steel material to prevent corrosion and contamination. Its sealing face materials are also usually made of food-grade materials to ensure sealing performance and hygienic performance.
Additionally, the valve features a smooth surface and a design with no dead ends, making it easy to clean and disinfect, meeting hygiene standards.
Compared to ordinary three-piece flange ball valves, sanitary three-piece flange ball valves require more quality control and testing during the manufacturing process to ensure their performance and reliability. In addition, during installation and use, it is also necessary to pay attention to compliance with relevant hygiene standards and specifications to ensure its long-term stable operation.
Sanitary three-piece flange ball valve is a high-quality, high-reliability valve suitable for the control and regulation of various sanitary pipes and equipment.
It can be adapted to different installation needs, such as mounting accessories: pneumatic head (PneumaticThree-piece flange ball valve), handles, handwheels, electric heads, actuators, electromagnetic actuators, filter actuators, regulators, explosion-proof actuators, signal actuators, etc.
