- Die casting aluminum piston.The precision-machined rack is chrome plated for optimal performance. It has a three point guiding system for moving stable and extended service life. High qualified seamless O-rings for air-tight sealing and long service life.
- Anti Blow out pinion design.
- Superior stability and field safety spring package (sizes 63 through 140). The PN series pneumatic actuator utilizes two embedded springs, an inner and outer springs allowing for five different spring torques. The design also allows equal and evenly distributed force to each piston extending service life.
- The encapsulated spring package, with corrosion-protected, can be easily-disassembled with a standard Allen wrench for conversion of double-acting to spring-return configuration on sizes 63 through 140.
- Anti-friction housing guide band ensures no metal to metal contact and provides wear protection between housing and piston for extended service life. Ideal for modulating or on/off control applications.
