With its new ISO FE-Series, AS-Schneider has developed a new valve technology that complies with the highest ISO15848-1 tightness class “A”. With a maximum permissible leak rate of 1.3 x 10-7 mbar * l /s (for a stem diameter of 7.5mm), this class even exceeds the requirements of TA-Luft.
By selecting the materials used on a targeted basis and carrying out appropriate surface treatment on them, the ISO FE-Series is even capable of coping with high pressures of 420bar (ASME class 2500) and handling a large number of switching cycles without problems.
The high-strength stem thread with a hard coating guarantees safe, wear-free operation. The non-rotating shaft seal ensures low actuating forces and minimal wear to the sealing elements. The special axial bearing of the stem/tapered connection has got what it takes. It is designed such that the highest spindle forces can be absorbed without any problem.
This new valve technology is used primarily for measuring pressure and differential pressure in all types of plant engineering, particularly in chemical and petrochemical plants and the offshore industry.
Customer benefits include increased plant efficiency due to low medium losses, virtually maintenance-free operation, products with long service lives and compliance with the highest requirements for leak tightness (Class A).
