The Story
The Drayton TRV4 Classic 15mm Angled TRV & Lockshield Valve Pack (MPN 07 05 180) is the go-to complete valve pair for standard 15mm domestic radiator installations — supplying both a TELL Class I-rated TRV4 angled thermostatic radiator valve with integral head and a matching chrome angled lockshield valve in a single box. Both valves share the TRV4 Classic white and chrome finish, ensuring a co-ordinated appearance. The TRV body includes reverse flow capability, double gland seal, and a pre-setting balancing facility.
Flush the system to BS7593 and treat with inhibitor before and after installation. Fit a by-pass valve where differential pressure across TRVs may exceed 0.2 bar.
One TRV4 Classic 15mm angled TRV body with integral white/chrome sensing head, plus one matching 15mm angled chrome lockshield valve — everything needed to connect both ends of a single radiator.
