New NAMUR valve range

Coils are available with intrinsic safety as well as with other protection methods such as non-sparking and encapsulated protection all to IEC EX (ATEX).

Jacqui Hanbury, product marketing manager at Festo, explains: "The VSNC valve is also ideal for dirty environments due to its re-breather function. This feature allows clean compressed air to be fed back to the spring chambers within the valve ensuring that the dirty air is kept out, which increases the life of the product. In addition, this can work in reverse in a clean or food environment, allowing compressed air from inside the valve to not reach the clean environment around it.”  

One valve within the new range offers both 3/2- or 5/2- way functions. This is achieved by rotating one single seal. This means there are no additional seals shipped with the product that have to be kept safe until required. With the VSNC, the function can be quickly and easily changed with no additional parts. Machine builders and maintenance engineers can reduce stock and associated costs as they can carry just one valve for use across a wide range of applications. Festo will supply two separate labels so that the valves can be correctly labelled in the field dependant on the functionality used.

The VSNC is robust, with flow rates of 1000L/min and offers an extended temperature range of -20 to 60°C. Coils are available in seven different voltages including AC and DC variants and with IP65 protection.  

The valves are available in two versions: a standard unit with plastic covers and a brass solenoid armature tube or a second valve with stainless steel solenoid armature tube and an aluminium body.  Both types are ex stock.
