1. Graceful Functionality and Intelligent EngineeringProduct Overview - A Glimpse into Technological Excellence
The ZYC Self-Operated Differential Pressure Control Valve, a marvel in pressure management, operates autonomously without the need for an external power source. Ingeniously responsive, it automatically adapts to pressure variations within your medium, neutralizing disruptions from residual pressure and pressure waves. This ensures a steady and reliable pressure differential at both the inlet and outlet, fostering seamless system stability.
This self-regulating differential pressure control valve is ideal for scenarios requiring sub-metering or within sophisticated automatic control systems, offering a seamless integration.
2. Product Characteristics - Unveiling the Hallmarks of Excellence
The valve showcases a double-disc design, minimizing valve stem imbalance forces. Its compact architecture is perfectly suited for heating and air conditioning water systems, maintaining a consistent pressure differential within controlled systems. Key attributes include:
1) Consistent Pressure Differential Control - Ensures constant system pressure differentiation.
2) Self-Regulation Support - Excludes external network pressure fluctuations from affecting the controlled system, ensuring unparalleled reliability.
3) Advanced Diaphragm Technology - Guarantees zero theoretical error and withstands pressure differentials up to 0.8MPa, setting new standards in performance.
4) Stepless Pressure Regulation - Offers an adjustable control pressure difference ratio of up to 25:1, providing precise adaptability.
5) Self-Operated Flow Control - In absence of independent system adjustment, it functions seamlessly as a self-operated flow control valve. Flow is set by:
a. Adjusting and controlling pressure differences,
b. Modulating system resistance for optimal performance.
6) Clog Elimination Feature - At maximum control pressure difference, the valve opens fully, allowing medium pressure to clear any debris accumulated in the double valve disc. Achieve this by closing the ball valve at the pressure guide pipe's end for 3-5 minutes.
7) High Precision Control - Delivers pressure difference control accuracy within ±5%.
3. Working Principle of Self-Operated Pressure Differential Control Valve - An Insight into Dynamic Functionality
Typically installed at the user inlet return water pipe, the pressure difference control valve demonstrates engineering prowess. The pressure guide pipe beneath the valve connects to the inlet water supply pipe. In this setup, P1 denotes the water supply pressure, P2 represents the return water pressure inside the valve, and P3 signifies the return water pressure outside the valve.
Upon setting the pressure difference △Pi (APi-P1-P2) as the valve's benchmark, the pressure P1 within the valve's lower membrane chamber balances with the thrust from P2 and the spring's compression deformation. This balance accurately determines the flow cross-sectional area A and the fluid flow coefficient through the valve. Even as flow rates vary, this delicate balance maintains △Pi unchanged.
For fluid-specific scenarios, with determined pipe diameters and flow resistance coefficients, the calculation of single pipe resistance is approximately represented by:
P = Kqm²
△P - Total Pipeline Resistance
K - Pipeline Impedance
qm - Traffic Flow Rate
The equation illustrates the direct proportionality between pipeline resistance and the square of mass flow rate as well as pipeline impedance. Variations in flow rate shift the pressure P2 in the upper membrane chamber, prompting the spool to adjust vertically. This alters A and the corresponding flow coefficient, accommodating total system resistance changes while maintaining a steady △Pi.

7. Installation and Debugging - A Complete Guide
1) Ensure that the flow direction of the medium is perfectly aligned with the arrow direction on the valve body. This crucial alignment guarantees optimal performance.
2) The pressure difference control valve should always be installed on the return pipe. The valve is seamlessly connected with the pressure guide pipe. The opposite end of this pipe must be linked to the water supply. We highly recommend installing a 1/2" ball valve at the water supply end of the pressure guide pipe. This setup enables the efficient activation of the blockage elimination function.
3) To maintain the pristine quality of water, a filter must be installed on the water supply pipe prior to the pressure guide pipe. This ensures the valve retains its top-tier automatic adjustment capability, unaffected by any impurities.
4) For seamless operation and monitoring, ensure both the water supply pipe and the return pipe before the valve are equipped with pressure gauges. This allows for easy adjustment and precise control of the pressure difference.
5) In cases where the system flow is unexpectedly large or small, investigate potential debris blockages on the valve plug, which may occur during pipeline component installation. Engage the 1/2" ball valve by closing it for 3-5 minutes. This may automatically clear light blockages. For persistent blockages, disassemble the valve to thoroughly inspect and remove any obstructions.
6) Control pressure difference adjustment method: Skillfully adjust the pressure regulating valve stem counterclockwise. Observe the pressure gauge to see the pressure difference decrease by 0.01MPa, incrementally increasing the control pressure difference from the initial 0.02MPa to 0.03MPa, and repeat as needed.
7) The valve is designed to operate within a working pressure difference of 0.02-0.3MPa. Should the working pressure difference exceed 0.3MPa post-installation, install a manual control valve on the water supply pipe. This step diminishes the pressure difference at the heat inlet device, preventing the valve from functioning under minimal opening conditions which can cause noise and drastically shorten the service life of the valve.
