Honeywell VR8605A1001 gas valve

Honeywell VR8605A1001U gas solenoid valves are a reliable means of controlling the flow of gas in various home systems, such as heating, radiators, boilers and water heaters. They have standard functionality and provide additional configuration options, including pressure control, the use of throttle valves, smooth ignition devices, two-level control and gas flow modulation. The Honeywell VR8605A 1001U compact automatic gas valves are available in a variety of power options, including mains and low-voltage, and also have different throughput capacities.

Each of these regulators is equipped with two electric actuators:

1. Safety valve control: The first mechanism is designed to control the opening of a safety valve of Class A or B in accordance with EN 161. This provides an additional level of security in gas supply systems.

2. Main valve control: The second mechanism is designed to control the opening of the main valve of class B, C or J in accordance with EN 161. This ensures accurate and efficient control of the gas flow in the system.

These regulators can work with various types of gases, including petroleum gases MFD group A (G110), MFD group B (G120), natural gas H (G20), natural gas L (G25) and liquefied gas LP (G30). Their flexibility and functionality make them an ideal choice for a variety of gas systems in home use.

General provisions        

The Resideo VR8605 A 1001U gas regulator is designed to control gas heating systems using DSI, HSI or IP ignition systems for the main burner. It provides reliable control of the burner by means of two-position electrical actuators.

The main characteristics of this regulator include:

1. Ignition systems: The regulator is compatible with DSI, HSI or IP ignition systems, which makes it ideal for gas heating systems with a main burner.

2. Burner control: The main burner is controlled using two-position electric actuators, providing accurate and reliable control of the gas flow.

3. Fine-mesh filter: The regulator includes an internal fine-mesh filter on the input side to protect the heating system from particles and contaminants. On request, it can be supplemented with an output mesh filter for additional filtration.

4. Variety of models: Different models with different closing strength are available, including B +B, B+J, B+C, A+ J and A+C options, allowing you to choose the most suitable for specific requirements.

5. Pressure monitoring: Fittings with an outer diameter of 9 mm on the inlet and outlet sides of the regulator are provided for monitoring and adjusting the burner pressure.

6. Flexible installation: The controller can be installed within a 90° angle in any direction from the vertical position of the two-position electric actuator, which provides flexibility in installation.

7. Easy installation: There are two threaded mounting holes in the base of the valve for reliable installation on the heating system.

8. Electrical connection: The two-position actuator of the main valve is equipped with an electrical connector according to DIN standard, which simplifies its connection to AMP connectors and ensures reliable control of the gas flow.

Principle of operation

The principle of operation of the VR8605A1001B gas solenoid valve is to automatically control the gas outlet pressure. The system has positive feedback, which ensures that the main valve is closed in case of a power failure or gas supply. This ensures a stable outlet pressure, regardless of changes in the inlet pressure. If there is no need for pressure regulation, it is possible to lock the regulator spring, which allows you to control the output pressure based on the full pressure of the “servogas”.

These Honeywell gas valves represent a reliable and efficient solution for heating and gas supply systems.
