This Inlet Valve (MPN EM748) is a genuine Villiers replacement part for the Villiers MK40 engine. Made from durable metal with a precision-machined stem and head, it controls the intake of the air-fuel mixture into the combustion chamber, helping maintain compression, smooth running, and fuel efficiency. It is a direct-fit valve engineered to match the original specification, making it suitable for routine servicing or a full rebuild of MK40-powered equipment commonly found in small construction and garden machinery. Supplied as unused old stock, the valve may show cosmetic tarnishing or storage marks but remains functionally sound. Choosing a genuine Villiers EM748 helps ensure correct fit, reliable sealing at the seat, and long service life in demanding operating conditions.
