Reviews
Drayton TRV4 Classic 15mm Straight is rated 4.7 out of 5 by 41.
Rated 5 out of 5 by from Quality! Replacement for an old Bulldog trv. Had a little less depth for the feed pipe than the old Bulldog trv. Fitted first time and no leaks. Nice smooth feel to the temperature setting.

Rated 5 out of 5 by from Good quality TRV I haven't fitted these yet but they appear to be solid and well made and good value as well due to a reduction in price.

Rated 5 out of 5 by from Drayton valves and lockshield valves Great top quality product. I have purchased this model of valve many times as I regard them as the best but never have I bought them at such a low price, unbeatable

Rated 1 out of 5 by from A word of warning I have been informed that the gland (rubber seal), releases an high temperature ‘mist’ as the valve pin moves up and down. The plastic becomes embrittlement and crumbles. Yes, you can replace both the seals and valve heads - but why would you want to?! Very disappointing.
