Actuators with safe function
Control of stop, cut-off or control valves with shutter position in a safe condition when removing power supply
Fill in the questionnaireDesignation:
The electric drive is designed to control shut-off, cut-off and control valves with bringing the valve gate to a safe position when the power supply is removed or a command is issued to move into the safe position.
Functions:
• Adjustable by user “normal” state: open, closed, safety position.
• Routine function to implement adjustments at low speeds with high frequency maintenance of the position and fast moving to the safety position at a preset speed.
• Combining a high efficiency gearbox, a highly efficient permanent magnet synchronous brushless motor and an in-built frequency converter allows using an in-built electric power storage unit, which ensures moving the output link of the electric drive to the required position.
• Energy storage in reliable supercapacitors with a double dielectric layer, where the guaranteed number of charge-discharge cycles is 50,000.
• Energy reserve from 1 to 10 travel cycles of the output link depending on the version of the electric drive and valve used.
• Compliance with the requirements of STO GAZPROM 2-4.1-212-2008 in terms of valve overlap time and compliance with the requirements for technological units of the I category of explosion safety in accordance with OPB (Federal Law No. 96 d/d 11.03.2013).
• Maintenance of the energy storage unit is not required during its entire service life.
• Compliance with functional safety standards according to GOST R IEC 61508 and GOST R IEC 61511 at the SIL2 level.
Features and Benefits:
• A block of supercapacitors built into the shell of the electric drive with secondary power and charge sources;
• Capability to equip a linear or part-turn electric drive with the "NO_NC" block of a standard design;
• High-efficient self-controlled synchronous electric motor with permanent magnets;
• In-built frequency converter;
• Cycloidal gearboxes and gearboxes with intermediate rolling elements;
• Universal control unit for all modifications of electric drives;
• In-built WIFI interface; ready to “Digital Economy”, “Industry 4.0 Ready”;
• Double insulated connection box.
