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 valve disc of the Cryogenic Swing Check Valve adopts a cantilevered swing structure, combined with precisely machined valve seat sealing surfaces, to achieve rapid response and reliable sealing, effectively preventing the reverse flow of the medium. The overall design of the valve complies with international standards such as BS 6364 and ISO 28921, and is suitable for low-temperature conditions in air separation plants, liquefied natural gas storage and transportation, and the chemical industry.
The dual plate check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
