Honeywell Gas solenoid valve VR4615VB1006B

The Honeywell VR4615VB1006B is a gas solenoid valve designed for safe gas flow control in home heating systems, boilers, and water heaters. It features two electrical actuators for safety and main valve control, with a maximum inlet pressure of 60 mbar and a flow capacity of 8.1 m³/h at a pressure drop of 10 mbar. The valve includes an internal fine-mesh filter, pressure regulation, and supports DSI, HSI, or IP ignition systems. It operates within an ambient temperature range of 0–60 °C and is CE compliant.

Parts of this type are selected by matching the connection type (flanged or compression fitting), inlet and outlet sizes, maximum operating pressure, and flow capacity to the system requirements. The valve must be installed within a 90° angle from the vertical position of the actuator, and the electrical connector should match the existing wiring standard (e.g., DIN or AMP). Before ordering, verify the nominal inlet pressure, pressure drop, and the presence of pressure measuring fittings on the inlet and outlet sides.

Common failure modes for gas solenoid valves include coil burnout, diaphragm rupture, or debris clogging the internal filter, leading to incomplete valve opening or closure. Symptoms may include burner ignition failure, unstable flame, or gas leakage. Check the coil continuity, inspect the diaphragm for damage, and clean or replace the filter if necessary.
