Flowshare Valve
THERMOSTATIC TWO-WAY FLOWSHARE VALVE
PRODUCT DATA
Application
Thermostatic flowshare valves control the output of radiators
in vertical one-pipe heating systems. Heating water not required is diverted through the bypass into the return. The
valve is controlled by a Honeywell radiator thermostat.
In the starting position the valve is open to the pre-set value.
The radiator proportion can be pre-set from 35 to 60% and is
supplied with a setting of 35%. The valve is suitable for use
with all Honeywell radiator thermostats.
An additional extension tail, injector and lockshield valve can
be installed to avoid heating up of the radiator through the
return – see ‘Accessories’ on page 3.
Features
• Stepless, concealed pre-setting of the flow, factory set
at 35% radiator proportion
• Low noise
• Exchange of valve insert or O-ring insert without
draining
• With beige protection cap
Design
The Flowshare Valve consists of:
•
Valve housing PN10 with externally threaded connections
for pipe, bypass and radiator
•
Pre-settable valve insert
•
Protection cap
Materials
•
Valve housing made of red bronze RG5 according to
DIN 1705
•
Valve housing made of brass with EPDM O-rings
•
Spindle made of stainless steel
•
Protection cap made of beige plastic

Function
The Flowshare Valve was designed for use with a radiator
thermostat. Depending on the room temperature heating
water is partly diverted through the outlet into the radiator and
partly through the bypass into the return pipeline. When the
room temperature falls the valve is opened by the radiator
thermostat and more heating water can flow into the radiator.
When the room temperature rises the valve is closed and the
heating water is diverted past the radiator into the bypass.
