FX Valve Seat SHP Complete — FX Impact Spare Part
S83303
The FX Valve Seat SHP Complete is a genuine FX Airguns factory replacement valve seat for the SHP (Smooth High Power) valve system used in FX Impact PCP air rifles. The SHP configuration is designed around higher air volumes and heavier projectiles — it uses a larger valve opening and a lighter return spring to maximise dwell time and drive slugs and high-power pellet loads with consistency. The valve seat in this system forms the precision sealing surface the valve pin bears against between shots; wear or damage here causes power drop-off, shot spread, and difficulty holding a stable tune. This complete valve seat replaces that sealing surface with a factory-specification part, restoring the tight tolerances the SHP system depends on. Confirm compatibility with your specific FX Impact variant and generation, and refer to the relevant FX service manual before carrying out any valve work.
