The SIF Series Standard Cylinder (With Valve Type) combines an ISO 15552 profile pneumatic cylinder with an integrated directional control valve, creating a compact and efficient actuator solution for industrial automation. By eliminating the need for separate external solenoid valves, the cylinder helps reduce pneumatic piping, wiring complexity, and installation time.
Its integrated control concept is particularly suitable for decentralized automation systems and modern machinery layouts. Combined with standardized ISO dimensions and flexible mounting options, the SIF Series offers reliable performance, simplified maintenance, and improved system efficiency for a wide range of pneumatic applications.
The SIF Series integrates pneumatic actuation and directional valve control into a single ISO 15552 compliant actuator package. This design simplifies machine construction by reducing external pneumatic components while maintaining the interchangeability and installation advantages of standard profile cylinders.
By placing the control valve directly on the cylinder assembly, the SIF Series provides an efficient solution for machine builders seeking cleaner layouts, faster installation, and easier system maintenance.

The SIF Series combines the advantages of ISO standardized cylinders with integrated pneumatic control technology.
Unlike conventional systems where cylinders and directional valves are installed separately, the SIF Series consolidates both functions into one compact assembly. This approach reduces the number of pneumatic connections and simplifies machine design while maintaining compatibility with ISO mounting dimensions.
The standardized design also facilitates equipment upgrades and component replacement.

To ensure stable airflow and efficient cylinder operation, different valve sizes are matched with corresponding cylinder bores.
| Cylinder Bore Size | Valve Model |
| 32 mm | 4M210 |
| 40 mm | 4M210 |
| 50 mm | 4M210 |
| 63 mm | 4M310 |
| 80 mm | 4M310 |
| 100 mm | 4M310 |
This optimized configuration helps maintain reliable switching performance and adequate airflow capacity across the entire cylinder range.

Large automation systems often benefit from distributed pneumatic architecture rather than centralized valve stations.
The SIF Series supports decentralized installation by integrating valve control directly at the actuator location. This arrangement offers several practical benefits:
● Shorter pneumatic tubing.
● Lower pressure losses.
● Faster machine assembly.
● Simplified maintenance.
● Easier future system expansion.
By reducing the distance between the valve and actuator, the system can also improve overall response consistency.

The integrated cylinder and valve structure reduces the number of external components required for installation.
Compared with traditional pneumatic layouts, the SIF Series helps minimize:
● External solenoid valves.
● Pneumatic fittings.
● Connecting hoses.
● Mounting brackets.
● Electrical wiring complexity.
This streamlined configuration contributes to lower installation costs and improved equipment organization.
A complete range of mounting accessories is available, allowing the cylinder to adapt to various machine designs and operating conditions.

The SIF Series is designed to improve long-term operational reliability by reducing external connection points that may become potential leakage sources.
The integrated actuator concept simplifies troubleshooting and servicing, as maintenance personnel can inspect and replace individual actuator assemblies more efficiently than conventional cylinder-valve combinations.
The compact profile structure also provides excellent corrosion resistance and supports continuous industrial operation.
