Overview
Fire specific gate valves, electric devices, and globe valves are used for gate valves, globe valves, diaphragm valves, etc. Stable performance, high control accuracy, favored by users. Valve electrical products include multi turn DZW and partial turn DQW, which are divided into outdoor type, explosion-proof type, integral type, integral explosion-proof type, regulating type, and regulating explosion-proof type according to the usage environment. Compared to valve electric devices, commonly known as Z-type Valves suitable for linear motion of opening and closing components, such as gate valves, globe valves, diaphragm valves, plunger valves, water gate valves, etc. Used for opening, closing, or regulating valves.
Product Details
Valve electric actuator is an automated device that converts electrical energy into mechanical energy and is used to drive valves (such as ball valves, butterfly valves, gate valves, etc.) to open, close, or regulate. It is widely used in industrial fields such as petroleum, chemical, power, water treatment, and metallurgy, and is a key equipment for achieving remote control, intelligence, and process automation. Here is a detailed introduction:
1Fire special gate valve electric deviceMain components
1. Electric motor
1.1 The core power source usually uses three-phase or single-phase AC motors, as well as DC motors (such as 24V DC).
1.2 Equipped with overheating protection device to prevent overload damage.
2. Deceleration mechanism
2.1 Gearboxes (worm gears, planetary gears, etc.) reduce motor speed and increase output torque.
2.2 Adapt to the opening and closing torque required for different valves.
3. Control unit
3.1 Integrated circuit board, receiving control signals (such as 4-20mA, 0-10V, or digital signals).
3.2 Support on-site button control, remote PLC/DCS control, or wireless communication (such as IoT modules).
4. Position feedback device
4.1 Potentiometers, encoders, or Hall sensors provide real-time feedback on valve opening (0-100%).
4.2 Used for closed-loop control to ensure precise positioning of valves.
5. Manual operating mechanism
5.1 Handwheel or clutch, the valve can be manually operated when power is off.
6. Shell and Protection
6.1 The material is mostly aluminum alloy or stainless steel, with a protection level of IP65/IP67 (dustproof and waterproof).
6.2 Explosion proof design (Ex d/IIC T6) for use in flammable and explosive environments.
IIFire special gate valve electric deviceClassification and selection
1. According to the exercise mode
Multi turn type: suitable for gate valves and globe valves (requiring multiple rotations).
Partial rotary: used for butterfly valves and ball valves（90 ° or 180 ° rotation).
Straight program: driving the linear motion of regulating valves (such as globe valves).
2. By Function
Switch type: Only fully open/Fully closed (such as solenoid valve).
Adjustable type: It can precisely control the opening (such as proportional integral adjustment).
3. Key parameters for selection
torque/Thrust: Match the required torque of the valve (taking into account the starting torque).
Power supply voltage: commonAC 220V/380V or DC 24V.
Control signal: analog quantity（4-20mA) or digital communication (Modbus, Profibus).
Protection and Explosion proof Level: Choose according to the environmentIP rating or explosion-proof certification.
IIIFire special gate valve electric actuatorCore functions and advantages
1. Automation control
andPLC/DCS system integration, achieving unmanned operation.
2. Fault protection
Overload, phase loss, and locked rotor protection extend the service life.
3. High precision adjustment
The precision of the adjustable actuator can reach± 0.5% FS (full range).
4. Quick response
The action time of the emergency shut-off valve can be as short as1-2 seconds.
