The electrical proportional valve is a component that outputs the working pressure and total flow rate proportional to the input working voltage data signal of the proportional electromagnetic coil inside the valve, causing the valve core to shift during operation, and changing the valve specifications. Valve core offset can also be feedback through mechanical equipment, hydraulic press, or electrical means. The electro-hydraulic proportional valve has various advantages, such as diverse types of methods, easy to form and control various electro-hydraulic system software in electrical and computer systems, high linearity, easy installation and application, and strong anti pollution work ability. Its main uses are gradually expanding. The selection of electrical proportional valve models for fast and easy optimization automation technology is included in Baidu. Product research and development, production, and manufacturing of plug-in proportional valves and proportional multi way valves take into account the application characteristics of engineering machinery equipment, and have the functions of pilot control, load sensing technology, and working pressure compensation. It has crucial practical significance for improving the overall technical strength of portable hydraulic equipment. The practical operation of motor control pilot, wireless remote control, and cable TV remote control have shown excellent application prospects.

Dongguan Tourui Machinery Co., Ltd. is located in Changping Town, Dongguan City, Guangdong Province. It is a technological innovation enterprise specializing in the research and development, production, and sales of adhesive tape whole factory equipment, as well as a series of equipment for optical and electronic soft material coating machines, slitting machines, rewinding machines, automatic cutting tables, and laminating rewinding and slitting machines. The company was named a private technology enterprise in Dongguan in 2012 and was awarded the title of National High tech Enterprise in 2015.

In July 2017, Mr. Li from the procurement department placed an order for 300 NITV1050-312L electrical proportional valves. We had originally planned to deliver them within 5 days, but after our colleagues worked overtime, the original plan was to advance the delivery time by 2 days, which was urgent for the customer. Mr. Li said that the delivery time was fast, and NNT employees were pleased with their responsible attitude.

NNT We have modern production and testing equipment, and we strictly manage and control all aspects of quality management to ensure that every product leaving the factory meets quality standards. And after-sales service is our strength, and the entire technical team has long-term and in-depth application cooperation with customers. We have received unanimous recognition from customers for responding quickly and resolving problems they encounter.
