Standard conditions

1. Indication of the flow rate in cubic meters per hour (m3 /h).

2. Registration of the output pressure using a sensor connected to a half-inch pipe, the length of which is 10 times the diameter of the pipe. This is done through a short hose, the length of which is equal to 5 pipe diameters.

3. Rated voltage.

4. Vertical position, meaning that the actuators are on top.

5. Nominal inlet pressure is 25 millibars, dry air at a temperature of 20 °C.

6. Ambient pressure = 1013 millibars.

7. Ambient temperature = 20 °C.

8. Output diaphragm with a diameter of 2.8 mm.

General provisions

The VR4605 CB 1082U gas solenoid valve is designed to control the gas flow in home heating systems. It is compatible with various ignition methods, such as DSI, HSI and IP, for the main burner. The control is carried out by two-position electrical devices. The valve has an internal fine-mesh filter and can be additionally equipped with an outlet mesh filter. Different models with different closing strength are available. To control and adjust the burner pressure, fittings with an outer diameter of 9 mm are installed. The regulator can be mounted within an angle of 90° from the vertical position. The valve base is equipped with two threaded mounting holes for mounting. The two-position actuator of the main valve has a DIN electrical connector for easy connection to AMP connectors.

Principle of operation

The principle of operation of the Honeywell VR4605CB1082B gas regulator is based on automatic control of the gas outlet pressure. This regulator is equipped with a built-in positive feedback system, which ensures reliable closure of the main valve in case of power loss or gas supply changes. This system ensures a stable output pressure regardless of input pressure fluctuations. When the regulator processes small volumes of gas, the outlet pressure is adjusted to compensate for the pressure difference. If pressure adjustment is not required, the regulator spring can be locked, which allows the full pressure of the “servogas” to determine the position of the main valve and control the output pressure.
