Economical Electric actuators are suitable for the automation of ball and butterfly valves for the industrial and construction sector. The usage of electronic components of last generation, together with precise mechanic, fruit of careful research and development, enables high performance and long-term reliability of the product.
The range has been manufactured with following characteristics:
■ The housing of the actuators provides a V0 self-extinguish class techno-polymer material.
■ Voltage range: 12VDC, 24VDC, 100-240VAC
■ The kinematics is made by steel and techno-polymer gear wheels, sustained by hardened steel pinions, mounted on self lubricating bushes and inserted in a strong structure of die-cast aluminum (excluding mod.VB015).
■ The connection part of the actuators with the valves, is made by a die-casted and painted aluminum with a dual drilling interface as per the ISO5211-DIN 3337 Standard.
■ The electronic circuit adjusts automatically the motor speed depending on the mechanical charge variations in order to drive the cycle always in the same time.
■ The whole range of actuators is provided with an electronic safety system for the torque control (torque limiter).
■ The whole range of actuators is standard provided of heater actives with the powered actuator.
■ The whole range of actuators can be supplied with positioner, programmable in standard (4-20 mA or 0-10V) reverse (20-4 mA or 10-0V) mode.
■ All electric actuators can be equipped with Rotary potentiometer rated (5KΩ).
■ All electric actuators (except model with 12VAC/DC power supply), can be equipped with battery backup for emergency control.
■ Optional middle position operation available for all version.
Badran manufactures two series of electric actuators:
• the series 85, with a self-extinguish technopolymer enclosure;
• the series 86, with a die-cast aluminum enclosure coated with polyester powder.
