How to determine whether the pneumatic ball valve with feedback and without feedback contains a positioner? Shanghai Dongfeng Valve Co., Ltd. has a complete and scientific quality management system. Our factory relies on the guidance of the scientific research department, actively listens to the opinions of users, pays attention to the cultivation and improvement of the quality of employees, and has good professional ethics. Our factory has strong technical force, excellent and complete equipment, supporting production of finished products, and complete quality inspection means. Over the years, we have consistently followed and pursued the business principle of "honoring contracts and keeping promises", adhered to the good after-sales service tradition, and let reputation and quality expand the market to occupy the market. Will the rusting of the pneumatic ball valve affect the water quality? The rusting of the pneumatic ball valve pipeline reduces the water delivery capacity, increases the power consumption, and the thickening of the growth ring in the pneumatic ball valve pipeline year by year, which not only affects the water supply quality, but also seriously affects the water passing section of the original pneumatic ball valve pipeline, reduces the water delivery capacity, and also increases the resistance of the pneumatic ball valve pipeline, resulting in a drop in the water supply pressure, In order to ensure the water pressure of water supply service, high lift pump must be used to increase the water pressure, which not only wastes electric energy, but also increases the water leakage.
The corrosion inside the pneumatic ball valve pipe has an impact on the water supply quality. Due to the long-term corrosion of water, a growth ring containing various components and bacteria is formed on the inner wall of the pneumatic ball valve pipe. Its thickness is mainly affected by the water quality, the material of the pneumatic ball valve pipe and the service time. The various components and bacteria contained in the rust scale will dissolve in the water, causing secondary pollution to the water quality In addition, after scaling of pneumatic ball valve pipes, the water quality is secondary polluted, so that the residual chlorine in the water is consumed by organic substances, so the total number of bacteria increases. There are pathogenic bacteria in these bacteria. There are also bacteria that can corrode the pneumatic ball valve pipeline. Some of these various bacteria seriously affect the water quality, while others aggravate the corrosion of the pneumatic ball valve pipeline, thus shortening the service life of the pneumatic ball valve pipeline. In line with the enterprise principle of cooperation and dedication, and users' peace of mind, our factory devotes excellent products and perfect services to our customers with the enterprise spirit of honesty, realism and pragmatism. Hengchang Company is willing to pursue zero defect product quality with high-quality and advanced products, perfect after-sales service, and the business philosophy that customers are always God.
