Description
Overview:
This genuine Lister Petter exhaust valve (OEM No. 201 80240) is a critical service part for Lister ST Range diesel engines, including ST variants. Built from heat-resistant alloy steel to withstand high combustion temperatures and corrosive exhaust gases, it controls exhaust flow from the cylinder and maintains correct sealing for compression and performance. It is suitable for industrial and agricultural machines powered by Lister ST engines, such as generators, pumps and compact plant. As unused old stock, the valve is new and unused but may show light tarnishing or storage marks that do not affect function. A direct replacement for the original part, it supports reliable starting, stable idle, proper valve timing, and long engine life when installed with serviceable guides, seats and springs.

- Genuine Lister Petter part for assured compatibility and build quality (OEM 201 80240)
- Heat-resistant alloy steel for durability under high temperature and load
- Precision-ground stem and seating face to maintain compression and sealing
- Direct-fit replacement in standard ST valve gear with no modifications required

- New old stock: may show cosmetic tarnish from storage only
