1.Product Overview
The ZYC Self-Operated Differential Pressure Control Valve (also known as a Pressure Controller) is a marvel of engineering that operates without the need for any external power. This innovative valve automatically adjusts in response to changes in the pressure of the medium it governs, deftly eliminating fluctuations typically caused by residual pressure and pressure waves within the pipeline. It maintains a consistent pressure differential at both the inlet and outlet, ensuring enhanced stability throughout the system.
This self-regulating differential pressure control valve shines in applications such as sub-metering or sophisticated automatic control systems, making it a versatile choice for varied requirements.
2. Product Characteristics
Boasting a double-disc structure, this valve experiences minimal unbalanced force on the valve stem. Its compact design is ideal for heating and air conditioning water systems, ensuring a constant pressure difference within the controlled system, while offering these remarkable characteristics:
1) Consistent Control of System Pressure Difference:
2) Supports Internal Self-Regulation of Controlled Systems: Skillfully excludes the impact of external network pressure fluctuations, safeguarding system integrity.
3) Featuring Advanced Diaphragm Technology: With a theoretical error of zero, this valve withstands a pressure difference of up to 0.8MPa.
4) Incorporating a Stepless Pressure Regulation Structure: The control pressure difference can be finely adjusted up to a ratio of 25:1.
5) Functioning as a Self-Operated Flow Control Valve when independent system adjustments are absent: How to set the flow:
a. Adjust and manage the magnitude of the pressure difference;
b. Adjust the resistance within the controlled system;
6) Featuring Blockage-Elimination Capability: At the maximum control pressure difference, the valve opens fully, allowing any dirt trapped in the double valve disc to be cleared under medium pressure. The procedure: simply close the ball valve at the end of the pressure guide pipe for 3-5 minutes.
7) Precision in Control Pressure Difference: Accuracy is upheld at ±5.
3. Working Principle of the Self-Operated Pressure Differential Control Valve
This intelligent pressure difference control valve is typically installed on the return water pipe at the user's inlet. The pressure guide pipe located beneath the valve connects to the inlet water supply pipe, where P1 represents the water supply pressure, P2 is the internal return water pressure, and P3 is the external return water pressure of the valve.
With the pressure difference △Pi (APi-P1-P2) set as the valve's pressure differential, the pressure P1 within the lower membrane chamber of the valve balances the thrust from P2 and the spring's compression deformation, determining both the flow cross-sectional area A and the flow coefficient for the fluid traversing the valve. As the flow rate shifts, the equilibrium of these forces prompts a change in the cross-sectional area A and the valve's flow coefficient, while ensuring △Pi remains steadfast.
Upon determining fluid properties, pipe diameter, and flow resistance coefficient, the formula for single pipe resistance is approximately expressed as:
P = Kqm²
△P ---- Total Pipeline Resistance;
K ----- Pipeline Impedance;
qm ---- Mass Flow Rate
This formula illustrates that pipeline resistance is directly proportional to both the square of the mass flow rate and the pipeline impedance. As the flow rate varies, the resulting change in pressure P2 within the upper membrane chamber prompts movement of the spool up or down, adjusting A and the corresponding flow coefficient to regulate the total system resistance within the valve, maintaining a consistent △Pi.

7.Installation and Debugging Guidelines
1) Ensure the medium's flow direction aligns perfectly with the arrow on the valve body; this guarantees optimal performance.
2) The pressure difference control valve must be strategically installed on the return pipe. The valve connects with the pressure guide pipe, which should further connect to the water supply pipe. To initiate the blockage elimination function, it is advisable to install a 1/2" ball valve at the water supply end of the pressure guide pipe.
3) Protect the valve's automatic adjustment capability by installing a filter on the water supply pipe before the pressure guide pipe to prevent degradation from poor water quality. valve operation can be compromised if this is not followed.
4) Equip the water supply and return pipes before the valve with pressure gauges. This facilitates easy pressure difference adjustment and control.
5) Should you notice an abnormal system flow, either excessive or insufficient, the cause might be debris obstructing the valve plug during pipeline component installation. Temporarily closing the 1/2" ball valve for 3-5 minutes might resolve light blockages automatically. If not, disassemble the valve to manually clear the blockage.
6) Method for Adjusting Control Pressure Difference: Turn the pressure regulating valve stem counterclockwise. Watch the pressure gauge as the pressure difference is reduced by 0.01MPa, gradually increasing the control pressure difference from 0.02MPa to 0.03MPa, step by step.
7) The valve operates within a pressure difference range of 0.02-0.03 MPa. If post-installation pressure difference exceeds 0.3MPa, it is crucial to install a manual control valve on the water supply pipe to adjust the pressure difference at the heat inlet device effectively. Failing to do so may cause the pressure difference valve to function under a minimal opening, resulting in noise and significantly reduced lifespan of the valve.
8. Installation and Adjustment of the Self-Operated Differential Pressure Regulating valve should be carefully followed for optimal functionality.
