Our company has been constantly exploring on the road of innovation. Relying on strong technical reserves and rich practical experience, the self-developed "valve positioner with memory function and valve fault self diagnosis method" has recently passed the review of the China National Intellectual Property Administration and issued a patent certificate for invention.

Innovation is the fundamental driving force for a company's sustainable development. As a well-known domestic regulating valve enterprise, our company always tracks the development trend of the international regulating valve industry, is committed to providing users with high-tech products with innovative products, and has increased product research and development investment year by year. This invention patent of "valve locator with memory function and valve fault self diagnosis method" is a proof of our company's fruitful achievements in continuous innovation.

The valve positioner with memory function and valve fault self diagnosis method invented by our company belong to the field of valve positioner technology. The basic principle of this patented technology is that the locator box contains a shielding box, an integrated circuit board, a central processing unit, a storage card with USB interface, and wiring terminals. The locator base is equipped with a gas amplifier and an electrical converter; The locator base is equipped with feedback gear and position sensor component I. The box body is equipped with output channel and exhaust channel, with pressure sensor I in the output channel and pressure sensor II in the exhaust channel. The method of the present invention involves the central processing unit receiving feedback signals from the position sensor and pressure sensor II, automatically calculating and comparing them with the signals specified in the control room according to a pre-set program. The present invention designs a USB memory storage module, which can self diagnose on-site valve faults regardless of whether the control system has HART or other communication protocols.

Our company has once again obtained this invention patent, which not only strongly proves our company's continuous innovation ability, but also fully demonstrates our strong technical reserve strength. It is also an effective weapon for our company to stand invincible in the increasingly fierce market competition, and demonstrates a trustworthy corporate brand image to customers.
