BYS-EX10 Explosion-proof electric actuators Electric Actuators
Product Specs
1, the latest isolation explosion-proof standard design

In accordance with the latest quarantine explosion-proof national standards GB, 3836.1-2010, GB3836.2-2010 regulations, design and use flameproof enclosure made of flameproof electric actuators, explosion-proof signs for Ex, D II, B, T4, Gb

2, patent technology

The core components of the servo controller of electric actuator is the company independently developed, and obtained two patents of invention and practical, it can be convenient and UNIC, 3610, NA, PS and other world famous manufacturers of the products, the actuator with control valve device.

3, small and light

The same shaft torque actuator, weight only DKJ, DKZ 1/3, the volume is similar products 1/2, electric actuator rated output torque of 600 Nm, the total weight of only 10 kg

4, high precision

The careful design of the electronic circuit makes the servo motor ahead of time to cut off the power supply, and reverse power, electric brake to ensure the positioning accuracy, effectively reduce the dead zone and self excitation. Accuracy up to 0.5%FS, dead zone 0.4 - 1.5%FS range adjustment.

5, high reliability

The unique electronic brake circuit is designed to reduce mechanical wear and system self excitation. To overcome the surge voltage, protection switch and other aspects have made significant technological breakthrough, it uses its own innovative design of solid state relay SSR, it has a rising rate of current suppression circuit, voltage suppression circuit, so the rate of rise of its load capacity and anti blocking ability strong.

6 、 strong anti-interference

The electromagnetic isolation technology with high precision and low power consumption is adopted to realize the isolation between the current input signal and the position output, so that the electromagnetic radiation, the power frequency and the common ground interference can be effectively prevented and can be used directly.

7, more innovation

Because only the contactless power switch can achieve no maintenance, long life and frequent start, because only without contact in order to achieve rapid conduction, cut off, to achieve accurate positioning, but also give up method, mechanical friction brake is successfully employed in braking technology, times improved sensitivity and control accuracy and reduce the maintenance workload.

8, protection function

The protection grade of the product is IP67, and the customer chooses the order to reach I P68 (which can be immersed in water), prevent the motor from overheating and burn out, and set up overheat protection and electrical and mechanical limit protection in the motor.

9 、 widely used

Petroleum, chemical, electric power, metallurgy, iron and steel, energy, building materials, light industry, food, water treatment and other industrial fields.

Features and Benefits

  • Compact Design
    The Luobai rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double-acting and spring-return units.
  • Degree of Travel
    The standard angle of rotation is 90°. Luobai actuators feature dual travel stops that provide ± 10° stroke rotation on both the opening and closing phases of the actuator stroke. 110° of travel in a standard 90° actuator!
  • Honed Bore for High Cycle Life
    Extruded aluminum body is internally machined and honed to exact specifications. Honing prevents dry spots from forming within the actuator bore and therefore eliminates premature seal failure—a critical aspect to long cycle-life. All internal and external surfaces are hard anodized for corrosion resistance, with all units permanently lubricated at the factory.
  • High-Cycle Bearings
    Shaft bearings isolate the pinion gear from the housing and support the shaft for high-cycle applications. Many competitive manufacturers do not provide this critical feature.
  • High Cycle-Life Wear Pads
    Pistons incorporate double wear pads (skates) to separate the rack from the actuator wall and serve as both guide and wear bearings.
  • Rugged Tooth Design
    The pinion teeth are engaged the full length and stroke of the piston, and designed for the toughest flow conditions. The pinion height allows manual override without needing to remove the indicator.
  • Multiple Output Shafts
    The female pinion drive is standard with a double-square output drive, and optional with a double-D drive, keyed drive and designs to meet your specific requirements.
  • Namur Mounting
    Namur VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners.
  • High Visibility Beacon
    External open/close indicator as standard, available for all rotations.
  • Safe Preloaded Spring Cartridges
    Epoxy-coated special steel springs are pre-loaded with non- metallic materials. The stainless steel end-cap fasteners are extra-long to allow for spring relaxation. All parts are corrosion-resistant.
  • Alternate Operating Media
    Air pressure operation from 40 to 150 psi (2 to 10 Bar). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator.
  • Stainless Steel Fasteners
    All external fasteners are corrosion-resistant stainless steel.
  • Optional Accessories
    Luobai offers a wide range of adapters for many different types of valves—including butterfly valves, ball valves and plug valves—as well as a variety of pneumatic and electric automation accessories suitable for diverse industrial environments.
  • Quality Assurance
    100% of all units are factory pressure and leak tested, and individually boxed for shipment.
  • Traceability
    All units are externally marked with a progressive traceable serial number.
  • Best Warranty In The Industry
    Luobai products are covered by our unlimited cycle-life warranty. Contact your local distributor or sales representative for more details.
