Zone valve - replacement head?

[Jennie]

Hi all,

Does anyone know if you can replacement heads for this zone valve? And if so, can you replace the head only (without having to drain the heating pipes)?

Thanks

Drayton ZA5 should do. You can replace the actuator head only (E.g. Screwfix 76959) but it is often cheaper to buy the whole valve (E.g. Screwfix 32455).
