Fairchild pressure reducing valves reduce inlet pressure to a desired outlet pressure through regulation, and automatically maintain a stable outlet pressure by relying on the energy of the medium itself. From a fluid mechanics perspective, a pressure reducing valve is a throttling element with variable local resistance. By changing the throttling area, the flow velocity and kinetic energy of the fluid are altered, resulting in different pressure losses, thereby achieving pressure reduction. Then, through the regulation of the control and adjustment system, the fluctuations in downstream pressure are balanced with the spring force, keeping the downstream pressure constant within a certain error range.

Fairchild Pressure Reducing Valve Principle

Operating Principle: The pressure reducing valve reduces water pressure by utilizing the local resistance of the flow channel within the valve. The pressure drop range is automatically adjusted by the pressure difference between the inlet and outlet water on both sides of the diaphragm or piston connected to the valve disc. The constant ratio pressure reduction principle utilizes the water pressure ratio control of the floating piston in the valve body; the pressure reduction ratio at the inlet and outlet ends is inversely proportional to the ratio of the piston areas on the inlet and outlet sides. This pressure-reducing valve operates smoothly without vibration; it has no springs inside the valve body, thus eliminating concerns about spring corrosion and metal fatigue failure; it has excellent sealing performance and prevents leakage, thereby reducing both dynamic pressure (when water is flowing) and static pressure (when the flow rate is 0); especially noteworthy is that it does not affect the water flow rate while reducing pressure.

The working principle of the American Fairchild pressure-reducing valve: The pressure-reducing valve regulates the flow rate of the medium by controlling the opening and closing of the valve body, reducing the pressure of the medium. Simultaneously, it uses the downstream pressure to regulate the opening and closing of the valve body, maintaining the downstream pressure within a certain range. Cooling water is sprayed into the valve body or downstream to lower the temperature of the medium. This type of valve is called a pressure-reducing and temperature-reducing valve. Pressure-reducing valves are included in the Quick and Easy Automation Selection Guide. The characteristic of this valve is that it maintains the outlet pressure and temperature within a certain range even when the inlet pressure is constantly changing.

Fault Phenomenon: Unstable pressure fluctuations

Fault Analysis:

1. Air mixed in the oil 2. Damping orifice sometimes gets blocked.

3. The roundness of the spool valve and valve body exceeds the specification, causing the valve to jam.

4. The spring is deformed or stuck in the spool valve, making it difficult for the spool valve to move, or the spring is too soft.

5. The steel ball is not round, the steel ball does not fit well with the valve seat, or the cone valve is not installed correctly.

Troubleshooting methods:

1. Remove air from the oil.

2. Clean the damping orifice.

3. Repair and grind the valve hole and spool valve.

4. Replace the spring.

5. Replace the steel ball or disassemble the cone valve for adjustment.

Fault phenomenon: Secondary pressure does not rise high enough.

Fault analysis:

1. External leakage.

2. Poor contact between the cone valve and the valve seat.

Troubleshooting methods:

1. Replace the seals, tighten the fastening screws, and ensure even torque.

2. Repair or replace.

Fault phenomenon: Does not reduce pressure.

Fault analysis:

1. The drain port is blocked; the drain pipe is connected to the return pipe and there is return pressure.

2. The main valve core is stuck in the fully open position.

Troubleshooting methods:

1. The drain pipe must be separate from the return pipe and return the oil to the tank separately.

2. Repair or replace the parts. Check oil quality.
