Honeywell Gas valve VR4605CB1082U

Honeywell VR4605CB1082U is a gas solenoid valve designed to regulate gas flow in residential heating systems. It uses two electric actuators for the safety valve and main valve under two-position electrical control. The valve has a flanged connection with 23 mm inlet and outlet diameters, handles a maximum inlet pressure of 60 mbar, and offers an air flow capacity of 3.8 m³/h at a pressure drop of 3 mbar. It is intended for vertical mounting with actuators on top, operates in ambient temperatures from 0 to 60 °C, and includes a built-in fine-mesh filter and a switchable soft-lite pressure system.

Gas valves of this type are selected by connection style, which is flanged, and by matching the inlet/outlet diameter and maximum inlet pressure to the existing gas train. Verify the flow capacity at the system's pressure drop to ensure it covers the burner consumption. For installation, orient the valve so the actuators are on top; some models allow operation at an angle of up to 90° from vertical. Secure the valve using its two threaded mounting holes, and connect the electrical supply to the DIN connector, ensuring the voltage rating matches (mains or low-voltage).
