Description
The Honeywell VR420VE5019-1000 is a servo-combi gas valve with a nominal diameter of 20 mm, designed for controlling gaseous fuel flow in gas burners and boilers. It operates with a supply voltage of 230 V at 60 Hz, has a maximum inlet pressure of 200 mbar, and a flow capacity of 1 m³/h. The valve body is made of aluminum alloy via injection molding, and the housing has an IP 40 rating. It includes a flange kit with one flange, sealing plug, O-ring, four screws, and one pressure measuring fitting installed. The valve meets EN 161 for mesh filters and EN 60335 series for electrical safety.
Further details
| Actuator Components | coil and a locking sleeve, inside which there is a plunger connected to a rubber valve |
|---|---|
| Application Purpose | control the flow of gaseous fuel in various devices, including powerful gas burners, atmospheric gas boilers, melting furnaces, incinerators and other gas-consuming devices |
| Built In Valve | two main valves, v1 and v2 |
| Ignition Systems Supported | spark ignition of the burner (dbi) and with pilot burner (ip) |
| Pressure Feedback Connection | open the pressure feedback connection (if provided) |
| Pressure Measuring Points | inlet and outlet pressure measuring fittings |
| Pressure Servo Controller | includes a pressure relief valve built into the regulator diaphragm |
| Regulator Classification | class c according to en 126/en 88 |
| Regulator Spring Lock | if no regulation is required, the full pressure of the "servogas" determines the position of the control valve based on the pressure |
| Restore Pressure Feedback | restore the pressure feedback connection (if provided) |
| Seal Material | hydrocarbon-resistant types of butadiene-acrylonitrile (nbr) and viton rubber |
| Strainer Cleaning | can be cleaned by unscrewing the inlet flange screws |
| Valve Classification | class a + a according to en 126/en 161 |
| Valve Inspection System Compatibility | vps in combination with the pressure switch |
| Valve V1 Operation | opens and closes quickly at all times |
Choosing and fitting
When selecting a replacement gas valve of this type, ensure the nominal diameter, supply voltage, frequency, and maximum inlet pressure match the existing system. Verify the flange connections and compatibility with pressure switches (e.g., C60VR series) if used. The valve must be installed according to the manufacturer's instructions, ensuring proper sealing and electrical connections.
Signs of failure
Common failures include sticking or leaking valves due to debris or wear, leading to improper gas flow or pressure fluctuations. Electrical issues may cause the valve to fail to open or close, resulting in burner ignition problems or unsafe operation. Check for blockages in the filter, damage to seals, and correct actuator operation.
