Danfoss Randall Automatic Balancing Valves now available from Sontay

Sontay, the market leading manufacturer and distributor of field control devices, has added the AB-QM series of automatic balancing valves from Danfoss Randall to its extensive range. Renowned for their quality performance, these automatic HVAC balancing valves provide Sontay customers with access to an easy to use, high quality range, proven to reduce installation and commissioning time and costs.

Danfoss Randall AB-QM valves are a new generation of versatile, multi-function valves which combine the three functions of a motorised control valve, a pressure control valve and a double regulating valve commissioning set in one device. Now available from Sontay, they can be used for balancing and controlling fan coils, chilled ceilings and air handling units and other HVAC equipment in constant flow or variable volume systems.

AB-QM valves are easy to size and set for a specific application. By fitting the standard valve with one of four different types of Danfoss actuators, they can be easily upgraded to a motorised control valve with full authority, supplying both temperature control and flow balancing in one, space-saving device. The three control functions are specifically matched to ensure optimum system performance and only one valve has to be mounted in a system instead of three.

The AB-QM is also the only automatic flow limiter which requires no isolating, drainage or venting should the flow section require changing. This ensures quick and simple installation and operation of its service without disrupting the system operation.

Sontay produces the most comprehensive control peripherals offering to the UK building services market. All Sontay products are renowned for their accuracy, reliability and discrete appearance and are used by many of the market leaders in the worldwide building controls industry. Their products and control solutions help improve building management system performance, reduce energy and maintenance costs and increase occupant comfort levels.
