Standard operating conditions

It is important to note its standard operating conditions:

1. Voltage and Position: The Resideo VK4115P 2002U gas valve operates at rated voltage and must be installed in an upright position to ensure optimal performance and safe operation.

2. Gas pressure: The nominal pressure of the inlet gas is 25 millibars under the condition of dry air and a temperature of 20°C. This is important to ensure the stable functioning of the system.

3. Gas flow measurement: Gas flow is measured in cubic meters per hour, which ensures accurate and reliable measurement of gas consumption in the system.

4. Ambient temperature: The system assumes operation at an ambient temperature of 20°C, which can be an important factor in the selection and installation.

5. Diaphragm: The gas regulator is equipped with a 2.8 mm diameter diaphragm, which plays a crucial role in regulating the gas flow and maintaining a stable pressure.

6. Ambient pressure: The ambient pressure should meet the standard atmospheric pressure and be 1013 millibars, ensuring reliable operating conditions.

7. Outlet pressure monitoring: The outlet pressure is regulated and monitored by a sensor that is connected to a 1/2-inch diameter pipe and a short hose, providing precise control of the gas flow.

Main Features

The Honeywell VK4115 P 2002U gas solenoid valve also has a number of characteristics and functions, such as various models with different levels of closing force, the presence of a built-in fine-mesh filter at the inlet, the possibility of mounting to the installation and a side gas outlet for the main and pilot burners. It also provides a choice of different types of electrical connections for better compatibility with other components of the burner control system.

The principle of operation

The principle of operation of the VK4115P2002B gas regulator is based on a positive feedback system, which ensures reliable and automatic control of the gas flow. The system includes a high-tech pressure servo controller and a pressure relief valve, working as follows:

• Initial state (without power supply): In the absence of power supply or other emergency situations, the main valve is in the closed position, and the gas flow is completely blocked, ensuring the safety of the system.
• Power supply: When the power supply is supplied, the system is activated. The gas begins to flow into the pressure servo controller.
• Opening of the main valve: The pressure regulator operates on the basis of positive feedback. It controls and regulates the gas pressure by transmitting the appropriate commands to the main valve. Under the influence of the servo controller, the main valve begins to open slowly, allowing gas to pass through it.
• Maintaining a stable pressure: The system continuously monitors the gas pressure and regulates the operation of the main valve so that the pressure remains at the set level. Even when the inlet pressure changes, the system adjusts the operation of the main valve to ensure a stable outlet pressure, which is important for the efficient and safe operation of the burner.
• Safety: In case of emergency overpressure or power failure, the system reacts immediately. The pressure relief valve turns on automatically, which leads to a quick and safe reduction of gas pressure in the system. This is an important means of ensuring safety, preventing possible emergencies.

Thus, the VK4115 P 2002B gas regulator ensures stable and reliable gas pressure in the burner control system and emergency shutdown in case of emergency situations, which plays an important role in ensuring the safety and efficiency of operations related to cobustion and heating.
