Features:

• Double acting (open / close by air) or spring return (either air close or air open and return to rest position by springs).
• Fully made in stainless materials, resistant to most of corrosive agents.
• Air, water, oil or other non-corrosive fluid feed, at a maximum pressure of 8 bars.
• 90º turn (quarter turn) with a 2º tolerance in opening / close operation.
• Temperature range from –32ºC to +90ºC under normal working conditions (intermittent peaks of –43ºC and 120ºC).
• Constant and high torque output.
• Visual position indicator.
• Can be fitted parallel or perpendicular to the pipe.
• Manual device for Emergency Operation (double acting only).

Options:

• Regulating limit switch box (electromechanical, inductive, magnetic or pneumatic) with NAMUR (VDI/VDE-3845) standard connection.
• Inductive or magnetic detectors.
• Box with built-in limit switches and solenoid valve.
• NAMUR solenoid valves (3-way for spring return and 5-way for double acting.
