Fluoroplastics feature exceptional properties
PTFE engineered parts exhibit almost universal chemical resistance over a wide temperature range.
The intermediate rings consist of aramid nonwoven fibres with a PTFE impregnation.
The very low coefficient of friction makes the packing set ideal for control valves, where both minimised friction and leakage are required.
But this packing set offers also superior performance for standard valve applications in the chemical and processing industry.
The sets can be supplied with cut or endless die-formed rings.
Key features and benefits include: an extremely low leakage rate compared with graphite sealing systems thanks to high cross-sectional density; low friction compared with graphite sealing systems because of dense PTFE impregnation; excellent performance under high temperatures and temperature cycling due to fibre reinforcement; excellent gland pressure retention compared to conventional standard PTFE packing; superior extrusion resistance and reduced cold flow compared to standard PTFE packing; and TA-Luft certification by MPA Stuttgart, April 2003.
