Drayton Trv4 Commercial Pack 07 05 187

Designed for commercial use, the chrome-finished Drayton TRV4 is a self-operating thermostatic radiator valve (TRV) offering room-by-room temperature control. This TRV works by simply regulating the flow of hot water to an individual radiator. With a range limiting feature and a marked frost protection setting, the TRV4 works over a temperature range of 10 to 27?C. The lockshield valve should be fitted on the opposite end of a radiator. This is used by the installer to regulate flow, balance the system or isolate the radiator for maintenance.
