GB type TRV Body
RADIATOR VALVE WITH OPTIONAL FLOW DIRECTION
PRODUCT DATA
Application
Thermostatic radiator valve bodies (TRV bodies) are fitted on
the supply or return of radiators or heat exchangers. Together
with a radiator thermostat, for example the Thera-3, they
control the room temperature by regulating the flow of hot
water into the heat exchanger. The temperature of different
rooms is controlled individually and energy is saved.
GB type TRV bodies have quiet operation and are fitted to the
supply or return of radiators on one-pipe or two-pipe systems
with medium to high flow rates. The GB type has optional flow
direction.
The valve insert can be replaced while the system is running
and without draining using the service tool (see ‘Accessories’
on page 2).
GB type TRV bodies are suitable for all Honeywell radiator
thermostats with M30 x 1,5 connection and 11,5 mm closing
dimensions.
Design
The thermostatic radiator valve body consists of:
• Valve housing PN10, DN15 with external thread connections to DIN/ISO228
• Valve insert with UBG-R type cartridge
• Two compression fittings, also suitable for supplied ex-
tended radiator tailpiece
• Protection cap
Materials
• Valve housing made of nickel-plated red bronze
• Valve insert made of brass with EPDM O-rings and soft
seals and stainless steel spindle
• Protection cap made of white plastic
• Nuts and tailpiece made of nickel-plated brass
Features
• Optional flow direction
• Suitable for the supply and return
• For heating systems with medium flow rates
• Dimensions according to HD1215, Part 2, Series GB
• Valve insert can be replaced while system is operating
and without draining the system
• Valve opening spring is not in the water
• Standard M30 x 1,5 thermostat connection

GB TYPE TRV BODY (V2047)
Function
Thermostatic radiator valves enable individual control of room
temperature and thus save energy.
The TRV body is controlled by the radiator thermostat. Air
from the room passing over the sensor of the radiator thermostat causes the sensor to expand when the temperature
rises. The sensor acts onto the valve spindle and this causes
Dimensions
the TRV body to close. When the temperature falls the sensor
contracts and the spring-loaded valve spindle is opened. The
TRV opens in proportion to the temperature of the sensor.
Only the amount of water required to maintain the room temperature set on the radiator thermostat can flow into the radiator.
NOTE: All dimensions in mm unless otherwise stated.
