Kromschroder Butterfly valve BVA65Z05 88300101

Kromschroder Butterfly valve BVA65Z05 88300101 is a rotary disc valve designed to shut off gas flow in burner and boiler systems. It is made of metal, originates from Germany, and is intended for use with air and low-pressure gases. The valve features flanged connections and can be operated manually or with a servo drive. It has a maximum overpressure of 500 mbar and is used for regulating air flow.

When selecting a replacement butterfly valve of this type, ensure the connection size and type (flanged) match the existing pipework. The actuation method (manual or servo drive) and electrical supply (if servo-driven) must correspond to the system's control output. Verify the pressure rating meets system requirements and that the valve is compatible with the gas type (e.g., natural gas, LPG, biogas).

Common failure modes for butterfly valves include leaking seats, seized butterfly plates, or defective actuator coils. Symptoms may include gas leaks, inability to regulate flow, or failure to open/close on command. Check for visible damage, proper sealing, and actuator operation.
