Description
Overview:
This genuine Villiers inlet valve is engineered for BSA 420cc industrial engines, where it controls the intake of air-fuel mixture into the combustion chamber. Manufactured from durable, heat‐resistant steel with a precision-ground head and stem, it provides a reliable seal against the valve seat to support correct compression and smooth running. Built to original specification for Villiers BSA 420cc units, it helps restore factory performance during top-end refreshes and full rebuilds. Supplied as unused old stock, the valve may show age-related tarnishing or storage marks but remains fully serviceable. A straightforward replacement for worn or pitted valves, it is suitable for stationary industrial engines commonly found on equipment such as pumps, generators, mixers, and compressors where consistent intake control is critical.
Key Features:
- Genuine Villiers part for assured fit and compatibility on BSA 420cc industrial engines
- Heat- and wear‐resistant steel construction for long service life under high temperatures
- Precision-ground sealing face and stem for reliable seating and stable compression
- Helps improve starting, idle quality, and overall engine efficiency
- Correct geometry and stem length to match original valve timing and lift
- Suitable for rebuilds, overhauls, and preventative maintenance of vintage engines

Typical Applications:
Used during intake-side repairs or rebuilds of Villiers BSA 420cc industrial engines powering stationary machinery. Typical scenarios include restoring compression after valve face wear, addressing intake leakage, or completing a scheduled top-end overhaul on equipment such as small generators, water pumps, site mixers, compressors, and other plant where dependable suction and mixture control are required.
