ALUMINIUM PNEUMATIC ACTUATORS TECHNICAL FEATURES Rotation Angle and Torques Aluminium actuators, 0º-90º or 0º-180º rotation angle to pilot ball, buttery and plug valves. Broad range of actuators, both Double Acting and Spring Return, from 17Nm to 5000 Nm at 6 bar. May be actioned with air or any nonagressive uid up to 8 bar pressure. Normal Working Temperature -32ºC to +90ºC INTERNALLY AND EXTERNALLY COATED BY CATAPHORESIS + RILSAN On demand: - Low temp. (-48ºC to +80ºC) - High temp. (-30ºC to +120ºC) Manufactured with materials resistant to oxidation. Silicone free. Spring Security System...

Stroke Adjustments External stroke adjustments to regulate opening (+85º to +92º) and closing (-2º to +5º) of the valve, both in double acting and spring return. Predominately used in buttery valves, to adjust closing of the disc. Mountin Mo Mounting Kits Broad ra Broad range of couplin couplings for kin any kind of valve ada adaptation. Conforming to all International Directives: ISO, DIN, NAMUR, VDI/VDE, ATEX, CE, DNV, PCT.
