A self-operated differential pressure control valve, also known as a "valve," is a device used to regulate the flow of fluid in a system by controlling the pressure difference across it. This type of valve works without external power sources or control systems, relying solely on the pressure differential created by the fluid flow to open or close.
The main advantage of a self-operated differential pressure control valve is its simplicity and reliability. It does not require any additional instruments or complex control systems, making it easier to install and maintain. Additionally, it can operate in a wide range of conditions, including high temperatures and pressures.
Product description:
ZYC self-operated differential pressure control valve is used in open and closed water circulation systems (such as hot water heating systems, air conditioning chilled water systems, etc.)
) is a kind of self-operated regulating valve, its function is to control the external disturbance (the pressure fluctuation of the network) and the internal disturbance (the internal resistance) of the controlled loop.
When changing), the pressure difference of the controlled loop is kept constant, which is suitable for the pressure difference control of the double-pipe system in the heating mode, ensuring the system
System stability, noise reduction, balanced resistance, fire heating network and hydraulic imbalance.
If the internal resistance of the control loop changes, the ZYC self-supporting differential pressure control valve can maintain a constant pressure difference between the applied and the controlled loop.
