Lockshield valve
The lockshield valve is approved to BS 2767-10.
The valve is fitted on the opposite end of the radiator to the TRV and is
solely used by the installer to regulate the flow of water/balance the
system, or to isolate the radiator.

TRV two pipe thermostatic radiator valve
with integral sensor and lockshield valve
Operating instructions
Approved to EN215:
All Drayton Thermostatic Radiator Valves are approved to the new
European Standard EN215, which supersedes BS.6284 1983.
Quality standards:
All Drayton Thermostatic Radiator Valves are manufactured in factories
assessed and certified to BS EN ISO9001.
General description
The Drayton TRV is a self-operating thermostatic radiator valve for
controlling the temperature in a room by regulating the flow of hot water
to a radiator. Operating over a temperature range of 10°C to 27°C it has a
range limiting feature which allows the valve to operate over a restricted
temperature range and a frost protection setting marked *.
Description of operation
The thermostatic sensor reacts to changes in temperature and by varying
the flow of hot water through its associated valve, controls the
temperature in the room.
Installation
Fit the TRV body to the radiator as for a normal radiator valve.
The valve may be fitted with the Sensing Head in either a vertical or
horizontal position. Drayton 15mm angle bodies now come with a reverse
flow feature as standard and can be fitted on the flow or return. The
Lockshield valve is then fitted at the opposite end of the radiator. Two
pipe bodies also have a pre-setting facility.
IMPORTANT: See Data Sheet D34, available on request, before using
the pre-setting device.
Following installation of the TRV4 the heating system should be
thoroughly flushed in accordance with BS7593 code of practice to remove
any traces of mineral oil. Formulations containing Mineral Oil MUST NOT
subsequently be added to the Heating system.
Also available
The Drayton 'DRAIN EASY' kit allows easy removal of a radiator valve on
most conventional systems without the need to drain down, loss of
corrosion inhibitor is also avoided.
IMPORTANT: The TRV4 Thermostatic Sensor IS NOT suitable for use
with the TRV3 range of bodies. A conversion head is available: Code No.
