AS Series

Spring-Return Pneumatic Valve Actuator

Next generation “compact” model provides a shorter and lighter canister for installations where space is a premium. SIL-3 Capable. Thrust up to 72,000 lbs.

Specifications

Highlights

The AS Series Spring-Return Pneumatic Valve Actuator’s SIL 3 capable rating is designed to provide reliable actuation solutions in critical applications without compromising the facilities Safety Instrumented Systems (SIS – compliant with IEC 61511/ISA 84).

  • Choose from a full range of readily available dimensional sizes and thrusts
  • Reduce design and developmental costs
  • Faster, simpler selection process improves your project planning and turnaround on proposals, feasibility studies, etc.
  • Springs are pre-compressed and factory-sealed inside a welded steel canister: no extended tie-rods required!
  • Modular Canisters are easily and safely removed for simple in-field servicing of actuator piston seals
