1.Product Overview
Introducing the ZYC Self-Operated Differential Pressure Control Valve This revolutionary valve, also called a pressure controller, operates seamlessly without requiring any external power source. It intuitively adjusts based on the pressure fluctuations of the medium it manages, deftly eliminating disruptions that can arise from residual pressure and pressure waves within the pipeline. By ensuring a stable pressure differential at the inlet and outlet, it guarantees unwavering system stability.
The self-operated differential pressure control valve is expertly designed to excel in environments that require sub-metering or automatic control systems.
2. Product Characteristics
Built with a robust double disc structure, the valve minimizes valve stem unbalance force and features a compact design, ideal for applications in heating or air conditioning water systems. Key features include:
1) Ensures a constant controlled system pressure difference:
2) Supports internal self-regulation of the system, effectively negating the impact of external network pressure fluctuations;
3) Utilizes an advanced technology diaphragm that achieves zero theoretical error while withstanding a pressure difference of up to 0.8MPa;
4) Features a cutting-edge stepless pressure regulation mechanism, allowing the control pressure difference to be finely tuned up to a ratio of 25:1;
5) When independent adjustment within the system is absent, the valve functions as a self-operated flow control valve. Flow setting methods include:
a. Adjusting and controlling the pressure difference magnitude;
b. Modifying the resistance within the controlled system;
6) Equipped with a blockage elimination feature: At maximum control pressure difference, the valve fully opens, allowing any debris trapped in the dual valve discs to be cleared under medium pressure. This is achieved by closing the ball valve at the end of the pressure guide pipe for 3-5 minutes;
7) Maintains a control pressure difference accuracy of ±5%.
3. Working Principle of the Self-Operated Pressure Differential Control Valve Valve
The pressure difference control valve is typically installed on the user's inlet return water pipe. The pressure guide pipe beneath the valve connects to the inlet water supply pipe, with P1 representing the water supply pressure, P2 the return water pressure inside the valve, and P3 the return water pressure outside the valve.
When the pressure difference △Pi (APi-P1-P2) is set within the valve, the pressure P1 in the lower membrane chamber balances with the thrust from P2 and the spring's compression deformation. This balance determines the flow cross-sectional area A and the valve's flow coefficient. As flow rates fluctuate, this force equilibrium causes variations in A and the flow coefficient, keeping △Pi consistent.
When fluid properties, pipe diameter, and flow resistance coefficients are established, the single pipe resistance formula is approximately:
P = Kqm²
△P ---- Total pipeline resistance;
K ----- Pipeline impedance;
qm ---- Flow rate
The formula illustrates that pipeline resistance is directly proportional to the square of the mass flow rate and the pipeline impedance. As the flow rate shifts, pressure P2 changes in the upper membrane chamber, prompting the spool to adjust vertically, thereby altering A and the corresponding flow coefficient to keep the system's total resistance relatively unchanged while maintaining constant △Pi.

7. Installation and Debugging
1) Ensure the fluid flow direction aligns perfectly with the arrow indicated on the valve body for optimal performance.
2) The pressure differential control valve must be strategically installed on the return pipe. The valve connects seamlessly with the pressure guide pipe, with its other end linked to the water supply pipe. Installing a 1/2" ball valve at the water supply end is recommended to facilitate efficient blockage clearance.
3) A high-quality filter is essential on the water supply pipe before the pressure guide pipe, ensuring the valve retains its automatic adjustment capabilities, even in suboptimal water conditions.
4) Equip the water supply and return pipes, positioned before the valve with precision pressure gauges. This setup enables easy adjustment and control of pressure differentials.
5) If system flow issues arise, such as being too high or too low, debris blockage on the valve plug may be the culprit. A 1/2" ball valve can be temporarily closed for 3-5 minutes to clear light blockages automatically. For persistent issues, disassembly of the valve may be necessary to effectively remove the blockage.
6) Adjusting Control Pressure: Rotate the pressure regulating valve stem counterclockwise, closely monitoring the pressure gauge. Once the pressure differential decreases by 0.01MPa, expect an increase in control pressure from 0.02MPa to 0.03MPa, and so forth.
7) The valve operates optimally within a working pressure differential of 0.02-0.03MPa. Should it exceed 0.3MPa post-installation, a manual control valve should be installed on the water supply pipe. This measure reduces the pressure differential across the heat inlet device, preventing the valve from operating noisily at minimal openings and extending its service life. valve.
