1.Valve body procurement QT450-10 material, spheroidization rate of 3 or more, mechanical properties fully up to standard, tensile strength 450Mpa, elongation rate greater than 10%, not easy to crack.
2.The valve body is solid body, the same DN weight is heavier than other manufacturers.
3.Seat rubber uses standard EPDM rubber, making the butterfly valve’s resilience and tension super stable and reliable, opening and closing more than 10,000 times without leakage.
4.The valve body uses an electrostatic powder thermal spraying process with a spray thickness of 250μm. The valve body is heated at 200°C for 3 hours, and the powder is cured at 180°C for 2 hours. After natural cooling, the surface adhesion is increased by 2 times than that of the ordinary powder, making it more environmentally friendly and weatherproof. Higher, to ensure that the valve body is not discolored for 36 months.
5.Introducing the PE heat-shrinking plastic packaging technology of electronic products. Each of the products of Ruderland is individually wrapped with a heat-shrinkable film and has a built-in desiccant. The air dust is isolated to facilitate storage and avoid corrosion caused by moisture.
