Flowcon launches automatic balancing valves

Essco Controls (Douglas Group) product story

Flowcon (Essco Controls' UK agent) has developed a range of pressure-independent automatic balancing valves.
Offering a wide choice of valves and actuators, the range's main attributes are that it achieves true balancing, automatically adjusting for pressure fluctuations, and provides significant savings on commissioning costs.
Flowcon (Essco Controls' UK agent) has developed a range of pressure-independent automatic balancing valves.
Technical manager, Cordell Batten, says: 'The latest flow technology ensures these accurately balanced systems produce increased levels of comfort in cooling or heating applications.
'A self-adjustment feature enables each valve to continuously self-balance.
'This delivers precisely the flow rate required by each terminal unit, independent of pressure fluctuations in the hydronic system.' Each Flowcon cartridge can be adjusted to set an accurate maximum flow rate limit to each circuit.
An extended choice of cartridges means an increase in the flow range - now from 40 to 16,100 litres per hour - using various cartridges and valve bodies ranging from DN15 to DN50.
The SME cartridge (typically for fan coil applications) offers an actuated control valve within a balancing valve.
Differential pressure-independent, this two-in-one device combines a full-stroke modulation control valve with an automatic balancing valve.
The modulation flow control has 100 per cent authority over the cartridge maximum pre-set flow setting.
Always using full stroke of the spindle means a dead band is avoided.
For larger diameters up to DN150, the range features Flowcon SH valves, which are externally adjustable but with a built-in diaphragm.
For thermostatic balancing valves, the T-Just cartridge limits the temperature to a maximum set on an external adjustment.
The cartridge has a manual override or can be fitted with an actuator for purging Legionella.
