CYLINDERS AND CONTROL VALVES ZRL1F series ZRL1F series actuators feature a particularly flat carriage design and include piston diameters of 16, 25, 32, 40, 50 and 63 mm with stroke lengths up to 5,700 mm. Suitable for filtered (50 μm) and unlubricated or lubricated compressed air. Please ensure continuous oiling when using lubricated compressed air. Please refer to our type code for the available variants and their corresponding type designations for your individual inquiry. Other special designs are also available on request. An articulated carrier is available as a separate accessory. Suitable for use in EX areas – ATEX II 2G EX h IIB T4 Gb –10 °C ≤ Ta ≤ +80 °C II 2D EX h IIIC T 130 °C Db max. 8 bar Working pressure: Temperature range: Barrel, end caps and piston axle: Seals: Sealing bands: Piston caps and sliding parts: 0.5– 8 bar –10 °C to 80 °C High-strength anodized aluminum Oil proof synthetic material (NBR/FPM) Stainless steel Abrasion-resistant plastic Example: ZRL1F.250250.KBWF.LL.N.EX Piston Ø [mm] Stroke min.–max.

Standard: with magnet ATEX Standard: no EX yes N without magnet For speeds >1 m/s, at which the seals are exposed to increased temperature development. SXF Same as standard, except: Stainless steel screws FPM seals For speeds >1 m/s. LE Same as standard, except: Air supply from one side (only for Ø 32, 40, 50, 63) KBW Same as standard, except: Flexible load connection KBWF Same as standard, except: Flexible load connection FPM seals For speeds >1 m/s. For each position in the type code, only one option can be selected by default. Piston Ø and stroke must always be defined as the minimum specification, e. g. ZRL1F.320100. Standard options are not explicitly defined, meaning the position in the type code remains empty, e. g. ZRL1F.320100.LL. 405
