Product Advantage:
1.The valve body and disc is all adopted QT450-10 material, the ball rate is above grade 3, the mechanical performance is fully up to standard, the tensile strength is 450Mpa, and the elongation rate is more than 10%. It is not easy to crack or freeze.
2.The valve body is solid body, the same caliber weight is heavier than other manufacturers.
3.The electric device is compact and beautiful in appearance, with a volume weight equivalent to only 1/3 of that of similar products, a large reduction in required space, light weight, and easy installation.
4.Seat 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.
5.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.
6.Introducing the PE heat-shrinking plastic packaging technology of electronic products. Each of the products of Bundor 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.
7.Every Bundor product has its own two-dimensional code identification from the accessories to the finished product, the unique ID number, to ensure that the product can be traced.
8.The Gende intelligent detection equipment integrates standard data measurement and pressure detection. Each inspection report is automatically generated. Each data and report is saved for 5 years, ensuring that the factory qualification rate reaches 100%.
9.Bundor brand products are underwritten by Pacific Insurance Company with 10 million quality. The warranty is 2 years. Pay two back if one bad within two years. The quality of the product is unconditional.
Standard Test:
Lever operated flange butterfly valve
Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.
Seat Test: 1.1 times the working pressure with water.
Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
Special Test: On request, any other test can be carried out according to special instruction by client.
