As a leading ball valve manufacturer RAYS FLOW CONTROL has been producing industrial ball valves to the highest quality standards with ultra-modern manufacturing technology and astute materials sourcing.
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.
Self-acting Temperature Control Valve is an energy-saving control device that does not require external driving energy. It relies on the temperature of the medium being regulated as the power source and the changes in the medium to automatically adjust according to the preset value. It integrates detection, control and execution functions into one valve and forms an independent instrument control system.
Self-acting Flow Control Valve 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.
