The bellows pressure reducing valve uses the opening of the opening and closing components inside the valve body to regulate the flow rate of the medium, reduce the pressure of the medium, and adjust the opening of the opening and closing components with the help of the pressure behind the valve, so as to maintain the pressure behind the valve within a certain range. In the case of continuous changes in inlet pressure, the outlet pressure is kept within the set range, protecting the subsequent living and production equipment.
Bellows pressure reducing valve is used on pipelines for steam, air, and other non corrosive gases with temperatures below 180C. Through regulation, the pressure of the medium passing through the valve is reduced to a desired outlet pressure, and the outlet pressure of the medium is kept relatively stable. However, the difference between the inlet pressure and the outlet pressure must be greater than or equal to 0.5bar.

Bellows pressure reducing valve is a type of valve used to regulate and stabilize medium pressure, its characters as below:
1. Accuracy and stability: The bellows pressure reducing valve can accurately adjust the pressure according to actual needs, ensuring the stability and safety of the production process.
2. Wide applicability: The bellows pressure reducing valve is suitable for multiple industries such as chemical, petroleum, pharmaceutical, food, etc., and can be customized according to different needs and environments.
3. Security: The bellows pressure reducing valve is equipped with multiple security protection measures such as overvoltage protection, overcurrent protection, etc., and capable of real-time monitoring and feedback to ensure the safety and reliability of the equipment.
4. Long service life: The bellows made of stainless steel material is corrosion-resistant and high-temperature resistant, and can operate stably for a long time in various harsh environments.
5. High sensitivity: Compared to piston type pressure reducing valves, bellows pressure reducing valves allow for small pressure differentials, have high sensitivity, and can quickly respond to pressure changes.
6. Good sealing: The bellows pressure reducing valve adopts bellows sealing, which will not rupture or leak like the rubber diaphragm, and has high safety. twelve
These characteristics make bellows pressure reducing valves highly practical and widely applicable in industrial production.
