Thermostatic regulator ensures constant water temperature

The 116 thermal balancing valve is intended to be installed in the return pipe of each recirculation circuit, automatically maintaining the desired water temperature.

The regulator controls the flow rate in accordance with the inlet water temperature using a dedicated internal thermostatic cartridge. When the water temperature approaches the set value, the amount of water recirculating is automatically reduced.

With a reputation earned over 30 years for providing innovative plumbing and heating solutions, Altecnic - part of the Caleffi group - has designed the 116 thermostatic regulator to deliver effective automatic thermal balancing when water supplied by the recirculation pump is distributed to other branches in the system.

Equipped with a thermal disinfection function - particularly useful if the water temperature exceeds 55˚C to 60˚C - the new regulator is available with a temperature gauge and a probe pocket for the temperature gauge. The 116 also offers a maximum working pressure of 10 bar, maximum differential pressure of 1 bar, a temperature adjustment range of 35˚C to 65˚C and a disinfection temperature of 70˚C.

If a temperature higher than 65˚C is reached, a second thermostatic sensor controls the disinfection process, allowing circulation independent of the action of the first thermostat. This ensures a flow of hot water through a special bypass as the temperature increases to 70˚C.

If the temperature rises above this, the flow through the bypass circuit is reduced to allow thermal balancing during the disinfection process. Should the temperature reach around 75˚C, the regulator ensures minimum flow rate so that water does not circulate at too high a temperature.

Among the accessories available for the 116 thermostatic regulator is a thermo-electric actuator, a 24V or 240V electric actuator and a cartridge for use with the electric actuator.

Gary Perry, Managing Director said: "Thermal balancing is a vitally important function in any plumbing and heating installation and this new product puts Altecnic at the forefront of this extremely important market sector."
