1.Actuator Body
The aluminium body is hard anodized inside and out to provide maximum resistance to abrasion and corrosion.
2.Pistons
Pistons are specially coated for corrosion resistance. Backlash is avoided by specially machined teeth. The pistons have a 3-point guiding system to ensure low friction operation along with another integrally machined guide between the pinion and the pistons.
3.Pinion
The hardened electroless nickel plated carbon steel shaft is blowout proof and corrosion resistant, teeth are machined for accuracy.
4.Stroke adjustment
External stainless steel stroke adjustment bolts provide 90°±5° stroke rotation limits.
5.O-rings
NBR rubber O-rings provide trouble-free operation at standard temperature ranges. For high and low temperature applications Viton or silicone.
6.Springs
Springs are positively contained and designed to release all compression before the end cap screws disengage from the body.
This safety feature prevents the accidental release of the springs and eliminates the possibility of personal harm.
7.End caps
End caps are epoxy coated to protect them from environmental corrosion. Double acting and spring return end caps are visibly different in order to allow quick determination of actuator type without having to look at the identification label.
8.Accessories
Mounting of limit switches, positioners, solenoid valves or indicators is accomplished via a NAMUR VDI/VDE 3845 mounting arrangement. Additionally, the height of the pinion shaft above the top of the actuator body is identical on all models, thereby simplifying the mounting arrangement for any NAMUR design accessory.
Testing
Every Simmel actuator is performance tested before being assigned a unique serial number for traceability.
双作用执行器的选型:
在正常操作条件下,双作用执行器考虑的安全系数为20%-30%。
示例:
阀门力矩=100Nm
安全力矩=100×(1+30%)=130Nm
气源压力=5Bar
对照双作用力矩表,选配双作用执行器规格为AT105DA。
如阀门介质方向有要求,或负载手轮机构、阀门定位装置、高温或低温订货请注明。
