Kromschroder Butterfly valve BVA80Z05H 88300351

The Kromschroder BVA80Z05H is a butterfly valve with a nominal diameter of DN 80, designed for regulating air flow in ventilation and burner systems. It operates at a working pressure of 0.5 bar and is intended for installation between two flanges. This valve is identified by SKU 88300351 and article numbers 88300351 and 624.274.020. The coil is replaceable separately from the valve body.

When selecting a replacement butterfly valve of this type, verify the nominal diameter matches the existing pipe size, and ensure the working pressure rating is suitable for the system. The valve is designed for flanged installation, so check the flange standard and bolt hole alignment. Confirm the coil voltage and electrical supply compatibility if the valve is actuated. Measure the overall length and ensure it fits within the available space.

Common failures for butterfly valves of this kind include coil burnout, leaking valve seat, and seized actuator mechanism. Symptoms may include improper air flow regulation, inability to open or close fully, or air leaks around the valve. Check the coil for continuity and inspect the valve seat for debris or wear.
