Description
Overview:
This Exhaust Valve is a Genuine Villiers part for the Villiers BSA 420cc Industrial Engine. It is a heat- and wear-resistant steel poppet valve designed to control the release of exhaust gases, helping the engine breathe correctly and maintain compression when closed. Built to original manufacturing standards, it offers a direct, like-for-like replacement for a worn or burnt exhaust valve on 420cc industrial power units. As unused old stock, the valve may show light tarnishing or storage marks, but this does not affect performance. Ideal for restoring reliable running on older plant and stationary equipment using the Villiers BSA 420cc platform, this part helps support smooth idle, consistent power delivery, and dependable service life under demanding operating temperatures.
Key Features:
- Genuine Villiers part for assured fit and compatibility on the BSA 420cc industrial engine
- Heat-resistant steel construction for durability under high exhaust temperatures
- Precision-ground seating face to promote a gas-tight seal and stable compression
- Direct-fit replacement to original specification for straightforward installation
- Supports reliable starting, smooth running, and consistent power output
- Unused old stock (NOS): original quality with possible cosmetic tarnish only
- Suitable for preventive maintenance or full top-end overhauls
- Helps minimise blow-by and exhaust leakage for efficient operation
Typical Applications:
Used in Villiers BSA 420cc industrial engines found on stationary and site equipment such as generators, pumps, compactors, mixers, and machinery drives. Suitable for workshop rebuilds, field repairs, and routine servicing where restoring correct exhaust valve function is needed to maintain reliability and performance.
