Replacement valve for the latest Alfamacchine / Minigraf underpinners, it's very common for underpinners to leak air from these valves once they need replacing.
*Since the Fletcher-Terry group acquired Alfamacchine they've started fitting the cheaper grey version valve which we've found has a very limited lifespan due to being made from plastic hence we now only stock the far better quality Gold version which has a metal body & spool.
*Seal kits are also available for the Gold valves: Link
