Effective impregnation and surface treatments have been used to improve\n mechanical sturdiness, sealing and resistance to corrosion of the components.\n\n\n\n\n WARNING\n This control must be installed in compliance with the rules in force.\n\n\n\n\n 2-5\n\f ELEKTROGAS – Technical Sheet EE156 - 01/24\n\n\n\n\nFunctioning and\napplication\n\n\n - When the combustion process is\n intermittent, a VF butterfly valve with\n solenoid actuator can be used, to adjust\n air volumes for low and high fire.\n\n\n\n\n VF..SR\n VF..L\n\n\n\n Fig. 1\n\n\n\n\n - In the annealing furnaces an auxiliary\n cooling is often required. Air volumes is\n controlled by a VF butterfly valve with\n solenoid actuator.\n\n VF..SR\n\n\n\n\n Fig. 2\n\n\n\n - In case of combustion process with\n pre-heated air, VFH butterfly valve can\n be used. Solenoid actuator is\n preferentially suitable for min/max\n regulation with heavy duty cycles.\n\n\n\n\n VFH..SL\n\n\n\n\n Fig. 3\n\n\n\n\n WARNING\n Location and mode of installation must be in compliance with local rules in force.\n\n\n\n\n 3-5\n\f ELEKTROGAS – Technical Sheet EE156 - 01/24\n\n\nTechnical\nspecifications Tab. 1\n Actuator type SR fast opening and fast closing\n SL slow opening and fast closing\n ST slow opening and slow closing\n Overall dimensions See table 2\n Rotation angle 0 / 90° minimum and maximum adjustable\n Ambient temperature -15°C / +60°C\n Voltage rating 230VAC 50/60Hz\n 110VAC 50/60Hz\n 120VAC 50/60Hz\n Voltage tolerance -15% / +10%\n Power consumption 45 W (starting180 W)\n Enclosure IP54 (EN 60529)\n (optional IP65)\n Cable gland M20x1,5 for terminal box\n PG 9 for ISO plug\n Coil winding insulation Class H (200°C)\n Coil thermal resistance Class F (155°C)\n Operating time SR: 1s opening/closing\n (0 - 90°) SL: ~4s opening / 1s closing\n ST: ~4s opening/closing\n\n\n VF DN40 DN50\n Rp3/4 Rp1 Rp1¼\n Rp1½ Rp2\n DN65 DN80 DN100 DN125 DN150\n VFT\n S..4      \n S..8    \n\n VFH DN40 DN50 DN65 DN80 DN100 DN125 DN150 DN200\n S..4  \n S..8      \n  Not recommended, use MZ servomotor.\n\n\n\n\n-\n\n\n\n\n Tab. 2\n Model Overall dimensions Weight\n [mm] [Kg]\n\n\n L3 H Ø\n SR4 126 160 100 5,0\n SL4 126 230 100 5,5\n ST4 126 240 100 5,6\n SR8 134 182 114 7,2\n SL8 134 252 114 7,7\n ST8 134 262 114 7,8\n\n\n\n\n Fig.4\n\n 4-5\n\f ELEKTROGAS – Technical Sheet EE156 - 01/24\n\n\n\n\nOrdering information\n Tab.3\n S R 4 A\n\n Model\n S\n\n Actuator type\n R fast opening and fast closing\n L slow opening and fast closing\n T slow opening and slow closing\n\n\n Actuator size\n 4\n 8\n\n\n Voltage\n A 230VAC 50/60Hz\n B 110VAC 50/60Hz\n N 120VAC 50/60Hz\n\n\n Special versions (some may be present concurrently)\n I Electrical connection with ISO 4400 plug\n M Special connection for open position indicator\n T Transparent cover to see led on electronic board\n T1 Transparent cover and ISO 4400 plug\n O IP65 protection with 1.5 m cable\n O1 IP65 protection with ISO 4400 plug\n X Ex execution for zone 2 and 22\n\n\n\n\n Manufacturer reserves the right to update or make technical changes without prior notice.\n\n\n\n\nStandards and\napprovals The actuators meet current European approval requirements regarding electrical safety:\n\n - Electromagnetic Compatibility (2014/30/EU)\n - Low Voltage Directive (2014/35/EU)\n - RoHS II (2011/65/EU)\n\n\n Quality Management System is certified according to UNI EN ISO 9001.\n\n\n\n\n Elektrogas is a brand name of:\n\n Elettromeccanica Delta S.p.A.\n Via Trieste 132\n The information in this document contains general 31030 Arcade (TV) – ITALY\n descriptions of technical options available and based\n on current specifications. phone +39 0422 874 068\n The company reserves the right to make changes in www.delta-elektrogas.com\n specifications and models as design improvements info@delta-elektrogas.com\n are introduced, without prior notice.\n Visit Elektrogas website for updates and further Copyright © 2024\n details.
