Part number: 8151227 General operating condition Data sheet Feature Value Size of valve actuator 160 Flange hole pattern F0710 Swivel angle 90 deg End-position adjusting range at 0° -5 deg ... 5 deg End-position adjusting range at nominal swivel angle -5 deg ... 5 deg Depth shaft connection 24 mm Standard connection for valve ISO 5211 Mounting position Any Mode of operation Single-acting Structural design Gear rack/pinion Closing direction Clockwise closing Symbol 00991266 Valve connection conforms to standard VDI/VDE 3845 (NAMUR) Connection point for positioner and position sensor conforms to standard VDI/VDE 3845 size AA 1 Devices type according to VDMA 66413 Safety device Safety function The safety function consists of the actuator switching to the defined safety switching position when the compressed air is switched off and the spring chamber is exhausted. This switching movement is achieved through the spring force of the spring assembl Safety integrity level (SIL) Up to SIL 2 low demand mode up to SIL 3 in a redundant architecture up to SIL 1 high demand mode Certified for safety function to ISO 13849 and IEC 61508 (SIL) Product can be used in safety-related parts of control systems up to SIL 2, low demand Product can be used in safety-related parts of control systems up to SIL 1, high demand up to SIL 3 in a redundant architecture Burst pressure 24 bar Operating pressure 2 bar ... 8 bar Operating pressure 29 psi ... 116 psi Nominal operating pressure 0.55 MPa Nominal operating pressure 5.5 bar Nominal operating pressure 79.75 psi Maritime classification See certificate CE marking (see declaration of conformity) as per EU explosion protection directive (ATEX) 12/30/25 - Subject to change - Festo SE & Co.
