Available since 1992 and still Britain s best selling range of Thermostatic Radiator Valves. Drayton s TRV4s set the standards for design, performance and quality, and are now A-Rating for energy efficiency. The range includes Lockshield and Pushfit packs to suit most domestic and commercial heating systems. It is strongly recommended that the differential pressure across the thermostatic valves should not exceed 0.2 bar to avoid flow related noise. A differential pressure regulating device such as an automatic bypass valve should be used. To avoid damage to the valves and the heating system components, and the formation of scale deposit in the hot water heating system, the system should be flushed and a proprietary inhibitor needed.
