Honeywell's hot water valve reduces wastage

Honeywell provides immediate hot water and reduces water wastage in buildings with multiple outlets through its low cost valve.

The Kombi 4 throttle and balancing valve is installed in the secondary returns of constant hot water systems to balance the system.

An optional thermostatic control attachment additionally maintains constant circulation temperature.

The Kombi 4 is small, costs less than other auto-balancing systems, and is easily fitted using DN15 - DN40 (0.5 inch to 1.5 inch) internal or external threads.

Its optional drainage adaptor provides convenient system drainage.

The valve allows thermal flushing as required daily for legionella prevention.

The temperature control is typically set for 50-55C and maintains this temperature during normal operation.

When water at above 70C is flushed through the system for thermal disinfection, the valve automatically opens further to ensure hot water is rapidly distributed in all risers and pipelines, whilst maintaining the balance.

When the thermal disinfection process is finished and the water temperature drops, the Honeywell Kombi 4 returns automatically to its standard control state.

The valve has a visible pre-setting dial with a concealed pre-setting handwheel.

The Kombi 4 is suitable for all potable water applications and is WRAS approved.

The valve housing and all parts with flow-contact are made of corrosion resistant red bronze.

It features a cavity free cartridge with maintenance free spindle sealing.

The spindle thread is isolated from the flow.
