The valve body is light in weight, strong in corrosion resistance, compact and beautiful in appearance, easy to install, strong in corrosion resistance, wide in application, sanitary and non-toxic in material, wear-resistant, easy to disassemble, and easy to maintain. By introducing the raw material requirements, design requirements, manufacturing requirements, performance requirements, test methods, system application requirements and the relationship between operating pressure and temperature in the international standards for plastic PVC valve products and test methods, we can understand the basic quality control requirements for plastic PVC valves, such as sealing test, torque test and fatigue strength test.
