Sontay launches valve and actuator range for HVAC applications

01 September 2011

Sontay's newly launched VE–x terminal valve and actuators and plug and seat valve assemblies offer much reduced installation costs, increased flexibility for system change and greater reliability for heating and chilled water HVAC applications with up to a 50% glycol mix. The new range is feature-packed to make installation as quick, simple and cost-effective as possible in fan coil units, small re-heaters and re-coolers in temperature control systems.

The compact housings ensure that products from within the range can be easily positioned in air handling units and plant room locations. Meanwhile, the raised shoulder within the casting also helps with placement in tight locations, especially when pipework insulation is present. No special tools are needed for installation.

Versatility and flexibility are also important features. The valve cartridges themselves are exchangeable, allowing easy replacement in situ and ensuring that costs are kept down should the specification change. Multiple KVS are available at every line size to ensure close matching of the chosen product to the valve authority. For high rise applications without any isolation loops, PN 16 static pressure rating options are available. 

Performance and reliability is enhanced through the use of a chemically resistant low zinc casting material – a significant advantage over non-coated competitor valve products on the market. Sontay's new terminal valve units feature in excess of a 50:1 turndown ratio and a soft seal, complete shut-off capability. Sontay's new terminal valve actuators have a tested life expectancy of over half a million cycles, aided by an end of travel shut-off function. Its reversible, brushless, synchronous electric motor maintains accurate positioning, providing creep free control with extreme accuracy.
