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

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.
