Product Introduction
The internal structure is mostly assembled with materials, and the entire machine shell is made of aluminum alloy die-casting. The superior features include simple wiring, stable performance, low energy consumption, beautiful appearance, light weight, small size, easy maintenance, simple installation, and the ability to operate manually and electrically.
Suitable for external power sources such as AC24V, AC110V, AC220V, AC380V, DC24V, DC220V, etc. The output switch time can be selected from various options such as 5S, 15S, 30S, and 60S. The product is widely used in automation system engineering such as buildings, petroleum, chemical, power, energy, building materials, water treatment, ships, papermaking, and smelting.
BR precision small electric actuators are suitable for some rotary valves (such as butterfly valves, ball valves, and air door baffles) and similar equipment. They can be used as angular stroke electric actuators with brackets. Adopting high-quality aluminum alloy die-casting shell, it has excellent properties such as fine smoothness, small size, light weight, maintenance free, and strong corrosion resistance. Due to its small size, it can be used in narrow places. There are many models available: A ordinary type, B Tianyuan contact type, H potentiometer type, C intelligent adjustment type. Remote and local control automatic functions can be achieved through external power supply control boxes or W, P external input signals, computer DCS, computer PLC and other signal sources. The product is widely used in building automation, water conservancy, papermaking, electricity, chemical and other automation control systems.
The specific advantages are as follows：
1. Small in size and large in torque, the overall volume and weight are only one-third of similar traditional products; The overall input power is small, the output torque is large, and the required installation space is small; Installation and transportation are very convenient.
2. A powerful electric motor designed based on the working characteristics of valves, with high starting torque, low starting current, and small turning inertia. The stator winding assembly is equipped with a built-in overheat protector (automatic recovery type). When the valve accidentally gets stuck, the protector will control the motor to stop and protect the safety of the entire equipment.
3. Precision gears are composed of multiple gears and shafts that are precisely tangent to each other. The gears and shafts are made of heat-treated high alloy steel, which has high strength, good resistance, and can withstand long-term fatigue load impact. Add molybdenum based grease to the gear mechanism to achieve permanent lubrication without the need for inspection or maintenance.
4. The mechanical limit device, stainless steel made mechanical travel limit bolts, and limit blocks can accurately adjust the travel mechanism to the desired angle. For the convenience of adjustment, this bolt is placed on the outside of the housing and locked in the desired position with a stainless steel nut after each adjustment.
5. The valve opening display lens and the body are bonded with glass glue, with a strong bonding height, making the product pollution-free, heat-resistant, and effectively resistant to corrosion from harsh environments such as rainwater and bubbles.
6. The manual handle can use a stainless steel handle to drive the valve to rotate during debugging or power-off, with S being clockwise and O being counterclockwise.
7. The cable interface is equipped with two G1/2 waterproof cable joints, which are used for cable and signal lines respectively to prevent interference.
8. The HD series of micro switches uses imported micro switches, which have excellent and reliable indicators such as contact quality, action life, and insulation performance.
9. The precision potentiometer adopts high-precision potentiometer, with a service life of up to 30000 times! Very suitable for small opening adjustment of valves! Effectively ensure the precision adjustment of electric valves.
10. Control modules encapsulated in resin have significant characteristics such as high decomposition, strong functionality, vibration resistance, long lifespan, and reliability.
11. The built-in control module of the servo mechanism continuously compares the input signal with the feedback signal of the potentiometer. When the balance is reached, the motor stops working, and then the output shaft keeps the valve in the corresponding position until the input signal changes. Ensure precise and continuous adjustment of valve opening
12. The automatic control intelligent integrated device has signal 4-20mA · DC input and output that can be controlled by computer PLC and DCS systems, proportional adjustment control and positioning, no need for manual control, position self-locking, simple wiring, stable and reliable performance, high control accuracy, fast response speed, etc.
13. Easy installation and simple connection.
14. Conventional power specifications: AC220V, AC110V, AC380V
