Patented, pressure balanced shaft
prevent axial forces acting on the
bearings. This results in high reliability,
long lifetime and lowwear.
Shaft and the bearing bushings,
mounted from inside, are of blow-out
safe design, with no need for external
circlips or snap rings, providing high
operational safety.
Robust anodised aluminium housings
ensure an even expansion under
thermal influences: no jamming of the
piston and a high level of corrosion
protection.
Optimally positioned, self-lubricating
sliding bands on the piston (made of
graphite filled Teflon) ensure low
friction operationwithminimal risk of
piston tilt, resulting in lowwear.
Left and right wounded springs avoid
torsion force andprovideproper
actuation function.
Interfaces comply withNAMUR
and ISO-standards.
Simple retrofitting of accessories,
such as solenoid valves, limit switch
and positioners.
Compact design allows extensive
direct mounting orientations.
