The Bentley Gothic antique copper TRV valve set is an opulent high grade twin pack from Evolve comprising a reversible Bentley Gothic thermostatic radiator valve with 15mm compression complete with a matching lockshield valve. To select the required room temperature, simply rotate the wheel handle clockwise or anti-clockwise between the first and fifth line.
Please note: Bentley TRVs are only suitable for use as a reverse flow valve when the system differential pressure across the valve does not exceed 0.25 bar. An auto bypass should be fitted in conjunction with all Bentley valves. An 8mm Allen key is suitable for the lockshield.
