28mm ABV

[kaboom]

Planning an install with 28mm primaries and wanted to go s plan- but then I saw the price of a 28mm ABV. Anyone know of one that's less than about £90+vat? Are they all angled or is there a straight one anywhere in 22mm?
If not it'll have to be Y plan and go in after the 3 port.
Ta.

Whats wrong with fitting a 28 x 15 reducer and using a 15mm auto bleed valve ?

ABV only has to pass enough to satisfy boiler minimum flow requirements with all other flow routes shut, so use a 28-28-22 tee before any valve and put a 22mm one in.

Danfoss do a 22mm straight ABV, more expensive than Myson/Honeywell ones.
