1. Low torque operation - Rotating valve seat design, easy and effortless opening and closing
2. Bidirectional zero leakage - Precisely ground sealing surfaces, in line with international standards
3. High pressure and high temperature resistance - Maximum pressure rating of PN100, temperature range of -196℃ to 550℃
4. Long service life - Hardened ball body, self-compensating valve seat design
5. Full diameter flow - Flow channels are of the same diameter as the pipeline, resulting in low pressure drop
6. Multiple drive methods - Supports manual/ pneumatic/electric control
7. Easy maintenance - Modular design, valve seats can be replaced quickly

The slow-closing check valve opens and closes the valve disc automatically due to the flow of the medium, and is a type of automatic valve used to prevent the backflow of the medium. It is mainly used to prevent backflow of the medium, prevent the reverse rotation of pumps and drive electric motors, and release the medium in containers. The check valve can also be used in pipelines that supply supplementary pressure to auxiliary systems where the pressure may rise above the system pressure.
An energy-saving control valve without external energy sources, used for flow control in process equipment involving non-corrosive liquids, gases, steam, etc.
Self-Operated Micro-Pressure Regulator does not require additional driving energy and is a kind of energy-saving control device; it is a specialized product for current most popular nitrogen sealing system of storage tanks.
