Self-operated Series

Self-acting Pressure Control Valve

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.…

Product Description

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.

Features & Benefits

 Modular Design: Product standardization, serialization, and generalization, with interchange.able components.

 Special Conditions: Based on practical engineering issues and to meet the differentiated needs ofcustomers, we provide highly personalized solutions. Our products are widelyapplicable in various industries such as: petroleum, chemical, pharmaceuti-cals, heating, and water conservancy. In particular, the self-operatednitrogen-sealing valve is at the forefront of industry technology for pressureregulation devices in storage tanks.

 Energy Saving: No external driving energy is required, the power source relies on the pressureor temperature of the regulated medium..
