An important advantage of this valve is its versatility, as it is designed to work with various types of gas, including heating gas, natural gas and liquefied gas. This makes it an ideal choice for a variety of applications where reliable and efficient control of the heating and combustion system is required. Honeywell VK4115G100B is a reliable partner in ensuring the safety and efficiency of these systems.

Standard working conditions

The standard operating conditions for the Honeywell VK4115G 1002B gas valve are important parameters that ensure its reliable and efficient operation. Here is detailed information about the standard operating conditions of this valve:

1. Nominal inlet gas pressure: 25 millibars. This value assumes the use of dry air at a temperature of 20 °C.

2. Output pressure monitoring: To monitor the output pressure, a sensor is used that is connected to a 1/2-inch diameter pipe. The length of this pipe is 10 times the diameter of the pipe, and the signal is transmitted through a short hose with a length equal to 5 pipe diameters.

3. Ambient temperature: The device is operated at an ambient temperature of 20°C.

4. Diaphragm: The gas valve is equipped with a 2.8mm diameter diaphragm, which plays an important role in regulating the gas flow.

5. Gas flow measurement: Gas flow information is displayed in cubic meters per hour, which ensures accurate measurement of gas consumption.

6. Ambient pressure: The device operates at an ambient pressure of 1013 millibars, which is the standard atmospheric pressure.

7. Voltage and Installation: The VK4115 G 1002B gas valve operates at rated voltage and must be installed in an upright position to ensure reliable and efficient operation.

These standard operating conditions are important for the correct and safe operation of the VK4115G1002 gas valve, and they ensure its optimal performance in many applications where monitoring of gas systems and burners is required.

General provisions

The Honeywell VK4115G 1002 valve provides many important features and options, making it a reliable component of the burner control system. Here is more detailed information about its main features and capabilities:

1. Inlet and outlet diameter: The inlet and outlet of the valve have a diameter of 18.6 millimeters, which facilitates their connection through the flanges and ensures a reliable connection.

2. Closing force level: Various models of this valve are available with different levels of closing force, such as B+ J, B+C, B+ B. This allows you to choose the appropriate option depending on the specific requirements and working conditions.

3. Built-in fine-mesh filter: There is a built-in fine-mesh filter at the input of the VK4115 G 1002 controller, which is designed to protect the system from particles and contaminants. If necessary, an additional output filter can be added for additional protection.

4. Mounting holes: Mounting holes are provided at the bottom of the valve, which ensures convenient installation and reliable placement of the valve on the installation.

5. Side gas outlet: There are variants of gas valves with side gas outlet that can be used for both the main and pilot burner. However, it is worth noting that such a side outlet can only be used with the flange collector of the burner.

6. Connection for pilot gas: At the outlet of the Honeywell VK4115G1002 gas solenoid valve there is a special connection for pilot gas with a diameter of 4 mm, which ensures reliable power to the pilot burner.

7. Different types of electrical connections: The user has the option of choosing different types of electrical connections, including connecting to the ignition regulator using a connector or using a plug-in rectifier unit for a standard DBI ignition system. It is also possible to choose options for operation at a voltage of 24V for joint use with other ignition regulators, with the exception of regulators of the S4565/S4585 series.

These characteristics make the Honeywell VK4115G 1002 valve a versatile and flexible component of the burner control system that can be customized and adapted to specific requirements and operating conditions.

The principle of operation

The principle of operation of the Honeywell VK4115 G 1002 gas valves, based on a positive feedback system, ensures reliable and safe control of the gas flow in the burner control system. Here is a detailed description of the principle of operation:

1. Initial state (without power supply): In the absence of power supply or in other emergency situations, the main valve is in the closed position, and the gas flow is completely blocked, ensuring the safety of the system.

2. Power supply: When the power supply is supplied, the system is activated. The gas begins to be supplied to the pressure servo controller.

3. Opening of the main valve: The pressure servo controller 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.

4. Maintaining a stable pressure: The system constantly 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.

5. 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, VK4115G1002 gas valves provide stable and reliable gas pressure in the burner control system, as well as emergency shutdown in case of emergency situations, which plays a crucial role in ensuring the safety and efficiency of operations related to combustion and heating.
