Honeywell VR4605C1086 gas valve

The Resideo VR4605C1086U are gas valves that are designed to safely regulate the flow of gas in domestic heating systems, heaters, boilers and water heaters. They provide standard functions and can be supplemented with various devices, such as a pressure regulator, a throttle valve, a smooth ignition device, two-level regulation and modulation of gas flow.

Honeywell VR4605C 1086U Compact Automatic combined gas valves can have different power options, including mains or low-voltage, and different throughput capacities. They are suitable for different types of gases, such as petroleum gases MFD group A (G110), MFD group B (G 120), natural gas H (G 20), natural gas L (G25) and liquefied gas LP (G30).

These valves include two electrical actuators: one for opening a safety valve of class A or B according to EN 161 and the other for opening the main valve of class B, C or J according to EN 161.

Thus, Honeywell VR4605 C 1086U gas solenoid valves and Honeywell VR4605C1086B Compact Automatic gas solenoid valves are reliable and safe devices.

General provisions

The Honeywell VR4605C 1086B is a CVI valve that is used in gas heating installations with DSI, HSI or IP ignition systems for the main burner. The main burner is controlled by two-position electrical actuators.

The VR4605C 1086 controller has an internal fine-mesh filter on the input side and can be equipped with an output mesh filter on request. Various models with different closing strength are available: B+ B, B + J, B+C, A+ J and A+C.

To control and adjust the burner pressure, the regulator has pressure measuring fittings with an outer diameter of 9 mm on the input and output sides. The regulator can be installed within an angle of 90° in any direction from the vertical position of the two-position electric actuator.

The base of the VR4605C 1086 gas valve has two threaded mounting holes for mounting on the heating system. The two-position actuator of the tracking type of the main valve is equipped with an electrical connector according to DIN standard and can be connected to AMP connectors.

Principle of operation

The VR4605C1086 gas control block provides automatic control of the gas outlet pressure using the built-in positive feedback system. This ensures that the main valve closes in the event of a power failure or gas supply, ensuring a stable outlet pressure, regardless of changes in the inlet pressure.
