ContQuality Control

POV VALVE firmly adheres to the quality policy and goal of “improving continuously and seeking zero defect”. We have established the internal quality assurance system at a level higher than international, domestic standards and customer requirements for the implementation of comprehensive, whole-course quality management. POV VALVE is provided with the first-class inspection center where various tests and inspections from product prototype test till product final inspection are independently completed. These tests and inspections include: radiographic flaw detection, dye penetrant flaw detection, magnetic particle flaw detection, ultrasonic flaw detection, spectrum analysis, positive material identification (PMI), metallographic examination, various mechanical properties tests, fire test, cryogenic test, high temperature test, vacuum test, fugitive emission test, high pressure gas test, hydrodynamic test, product life test, hydraulic test and other valve tests. In order to ensure the blank quality, POV VALVE has established its own foundry, so that all chains from production of raw materials till delivery of finished products are effectively controlled. While practicing the “zero defect” internally, POV VALVE also adopts advanced data statistical analysis to continually improve process control and management capability.

Quality control is a crucial aspect of the manufacturing process for Bal Valve And butterfly valve, ensuring their reliable performance, durability, and safety in various industrial applications. Strict quality control measures are implemented at every stage of the production process, from material selection to design, fabrication, assembly, and testing.

High-quality materials, such as stainless steel or other corrosion-resistant alloys, are chosen for Bal Valve and butterfly valves to withstand a wide range of media types and operating conditions. The valve design undergoes comprehensive analysis and validation to confirm that it meets industry standards, regulatory requirements, and customer specifications.

During fabrication and assembly, advanced manufacturing techniques and skilled craftsmanship are employed to maintain tight tolerances, ensure proper alignment of components, and secure connections. This attention to detail results in a robust and reliable butterfly valve that delivers excellent functionality and longevity.

Each Bal Valve And butterfly valve is subjected to a series of tests, including pressure tests, leakage tests, and functional tests, to verify its performance under different pressure and temperature conditions. These tests also ensure that the valve’s sealing mechanisms, such as gaskets or elastomers, provide a tight seal to prevent leaks and maintain the integrity of the fluid control system.

In addition to in-house quality control measures, third-party certifications from recognized organizations, such as API, ASME, or ISO, can further attest to the quality and reliability of Bal Valve And  butterfly valves. By adhering to stringent quality control procedures throughout the entire production process, Bal Valve ensures that their butterfly valves meet the demands of various industries and applications, providing smooth operation, reduced maintenance, and a long service life.
