ZYC Self-acting Differential Pressure Control Valve

Short Description:

The ZYC self-operated differential pressure control valve is an energy-saving valve that maintains constant differential pressure through the self-pressure change of the medium. It is mainly used in fluid control systems to maintain the set differential pressure and optimize system operation efficiency. By balancing pipeline resistance, it reduces water flow noise and solves the problem of unstable operation caused by uneven pressure in heating networks or air conditioning systems.

Product Tags

Through automatic adjustment of the valve opening, it counteracts pressure fluctuations in the pipeline network to ensure stable supply and return water differential pressure in the controlled system, avoiding hydraulic imbalance caused by flow changes. It reduces energy waste caused by pressure fluctuations in the system, balances the hydraulic conditions of heating or air conditioning systems, and improves overall efficiency.

Application Scenarios

Heating Systems
Particularly suitable for two-pipe heating systems and household metering scenarios. Installed on the return water pipe at the user entrance, it ensures balanced flow in each branch through constant differential pressure, solving hydraulic imbalance issues.
Central Air Conditioning Systems
Used in variable flow air conditioning water systems to automatically adjust the flow of cooling water or hot water to adapt to load changes, ensuring efficient operation of terminal devices.
Industrial Fluid Transportation
Controls pipeline pressure to prevent excessive or insufficient pressure, protecting equipment safety. Commonly used in non-corrosive liquid transportation scenarios such as water treatment and oil circuits.

Other Fields
Some models can be extended to parallel systems of fire protection and domestic water, achieving flow control by adjusting the water supply direction.
