Ductile Iron Flange Connection Self Operated Differential Pressure Control Valve
Product introduction:
A self operated differential pressure control valve is an energy-saving product that utilizes the pressure changes of the medium itself to self control and maintain the constant pressure difference of the medium flowing through the controlled system. Suitable for pressure difference control using dual pipe systems for air conditioning and heating, as well as for household metering heating systems and variable flow air conditioning systems, ensuring that the pressure difference of the system remains basically unchanged, reducing noise, balancing resistance, and eliminating hydraulic imbalance in the heating network. According to the installation position, it can be divided into water supply (G) and return water (H), which are characterized by not requiring external power or control signals, but relying on pressure differential sensors inside the pipeline to achieve automatic flow regulation. Suitable for pressure difference control using a dual pipe system for heating, balancing the heating power and water flow in the community's heating network.

Product features:
1. Automatic adjustment: Through the built-in pressure differential sensor, the valve can automatically adjust its opening according to the pressure changes in the pipeline system, thereby achieving automatic flow control.
2. No need for external energy: Unlike traditional electric or pneumatic control valves, self operated differential pressure control valves do not require external power or pneumatic sources to achieve regulation, thereby reducing energy consumption and system complexity.
3. Environmental suitability: Due to the absence of external control signals, self operated differential pressure control valves have lower requirements for environmental conditions and can operate stably in harsh environments.
4. Precision control: This type of valve can provide precise flow control, ensuring that the flow in the pipeline system meets the design requirements.
