Water Ingress Protected
O-Rings are fitted on bodies, caps and so on,this ensure water ingress protected.
Standardization
The shaft driven accessory interface conforms to NAMUR and is identical on all NSF Series models, allowing standardization of accessory mounting hardware and installation practices.
Wear Resistant
The guide rod and piston rod have an advanced surface treatment, which combined with self-lubricating bearings, provides superior wear resistance and extends the life of all sliding components.
High Efficiency
The piston rod and guide block connection superior surface finishes and self-lubricating bearings maximize input energy transfer directly to the valve stem, efficiency is further enhanced by the tension-loaded spring, minimizing radial loads on the piston rod.
Corrosion Resistant
The NSF series actuators incorporate over three stages of internal and external coatings to resist severe weather,chemical and petroleum environments. The inner surface of cylinder is coated by PTFE, enhanced corrosion resistant and self-lubricating
