Omal pneumatic actuator made by stainless steel / INOX precision casting. It is available as Double Acting (DA) and Spring Return (SR) in torques 15Nm - 480Nm & 15 Nm to 240 Nm respectively.
Mounting flange according to DIN/ISO 5211 DIN 3337; F03 - F05 - F07 - F10
VDI/VDE 3845 connection for accessories.
Rotation angle 90°.
DA Torque: directly proportional to the air supply and SR Torque: the return torque depends on spring action only notwithstanding the air supply. The spring is provided in four different sizes. The actuator automatic closing takes place in clockwise direction by means of its springs.
The code numbers after the DA/SR letters always correspond to the breakaway torque in Nm by 5,6 bar air supply.
Sizes from DA60 / SR30 direct connection with NAMUR solenoid valve.
Sizes DA15 - DA30 / SR15 can be provided with NAMUR plate on request.
ATEX version in conformity with directive 2014-34-EU.
Temperature: from -20°C to +80°C.
Air supply: 5,6 bar; maximum 8,4 bar.
Operating media: compressed filtered air, not necessarily lubricated. In case of lubricated air, either non detergent oil or NBR compatible oil, must be used.
