SF Series Pneumatic Actuator

Features

Water Ingress Protected:
O-Ring are fitted on bodies, caps and so on, which ensure water ingress protected.

ISO Valve Mounting:
The SF Series Actuators interface meets ISO standard, and meets the dimensional requirements of ISO defined for each torque Range.

Connection Standard:
The shaft driven accessory interface conforms to NUMAR and is identical on all SF 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 combine with self-lubricating bearing 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-laded spring, minimizing radial loads on the piston rod.

Corrosion Resistant:
The SF 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.

Modular design:
SF series actuators have available, field-servi-ceable drive, power, spring and override modules, The modules are removable, serviceable and interchangeable while mounted to the valve, Modules are available for separate purchase to reduce spareparts inventory.

Safe Spring Module:
To ensure the safety of personnel during installation and maintenance, The spring module has been designed so that it can only be removed from the power module with the spring in the fully extended position. This prevents accidental release of the spring force , protecting personnel from injury and the actuator from accidental damage.
