The self-regulating control valve is an energy-saving control device that does not require external driving energy. It relies on the pressure or temperature of the medium being regulated as its power source, automatically adjusting according to set values based on changes in the medium. This valve integrates multiple functions of detection and control into one unit, forming an independent instrument control system. The self-operated control valve adopts a standard modular design. Our products are characterized by: standardization, serialization, and generalization. This achieves a high level of these three aspects. The components of the self-operated pressure regulator and differential pressure regulator are interchangeable. If the control conditions change, the spring & diaphragm components can be easily replaced. The accuracy of the self-operated control valve surpasses that of similar products, and it also offers high stability. Diversified product series: self-operated pressure regulator, self-operated micro-pressure regulator, self-operated temperature regulator, self-operated flow regulator, self-operated nitrogen-sealing valve, and self-operated (combined) regulator...
The Side Entry Cryogenic Trunnion Mounted Ball Valve fixed ball valve is a type of fixed ball valve that adopts an upper mounted structure. The ball is installed and disassembled through the upper part of the valve body, and can work stably under ultra-low temperature conditions. When closed, the valve stem drives the ball to rotate, making the hole on the ball perpendicular to the valve body channel, thereby cutting off the medium; When opened, the valve stem drives the ball to rotate 90 °, aligning the hole on the ball with the valve body channel, and the medium can pass through.
The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
