1. Controls the Butterfly Actuator Speed with greater accuracy by a
unique SMC Throttling Design
2. Namur mounting allows for installation between the Actuator and
SMC PPS Body Solenoid Valve or on a Delrin Sub-base
3. Will help reduce "water hammer" by throttling the actuator speed
allowing for more precise Actuator control
4. Stainless Steel adjustment screws
5. Designed to work with a variety of Actuator sizes
6. Stainless Steel or Anodized Aluminum options
7. Does not completely close off allowing the actuator to still function
if the operator leaves it in the closed speed condition
8. Captive "O" rings allow for overhead mounting to reduce seal loss
9. Ships as a "Kit" with S/S mounting screws
10. Installs easily in either Namur mounting position
