Naidong Valve (Shanghai) Co., Ltd. is a technical enterprise specializing in valve research and development, design, manufacturing, sales, and service in China. Our products are finely processed, aesthetically pleasing in appearance, stable in performance, and adhere to the manufacturing philosophy of quality first. The company has carefully launched an earlier generation of refined series improved products. Based on the various advantages of similar products, a large number of targeted improvements have been made according to the quality status of the products in practical applications. The new products highlight obvious advantages in reliability, practicality, and novelty, and have been widely used in fields such as petroleum, chemical, food, medicine, municipal, fire protection, and water supply.

The multifunctional CNC electro-hydraulic valve produced by Naidong Valve has a comprehensive characteristic computer testing line for electro-hydraulic valves in the industry, which can effectively control the repeatability error of each batch oil delivery to no more than 1 liter for each electro-hydraulic valve, and can be refilled (for example, a 4-inch electro-hydraulic valve can dispense 2 liters of oil each time), ensuring seamless opening and closing performance. In addition to multifunctional electro-hydraulic valves used in oil, chemical, natural gas, and liquefied gas industries, we also produce reverse, reverse, and multifunctional needle valve type CNC electro-hydraulic valves; All stainless steel; Low temperature valve, piston type electro-hydraulic valve, intelligent electro-hydraulic valve, water valve, etc. Up to now, it has become a professional manufacturer and developer of multifunctional electro-hydraulic valves in China; And a professional enterprise specializing in the maintenance and modification of various specifications of electro-hydraulic valves imported from abroad. After successfully mastering the manufacturing method of the CNC piston type (788 type) valve, in response to the requirements of high pressure, large flow rate, and stronger anti water hammer ability in domestic oil delivery pipelines, its service life is longer, measurement is more accurate, and maintenance is more convenient and concise.

The company will uphold the spirit of integrity, innovation, pragmatism, and development, providing high-quality products and services to new and old customers, fully meeting their product needs, and becoming your trusted high-quality valve technology partner
