Manual gate valve
Manual gate valve is a valve that uses gate plate as opening and closing parts and moves vertically along the seat axis to realize the opening and closing action. The main advantages of the gate valve are smooth passage, low fluid resistance and small opening and closing torque. The main disadvantage is that the sealing surface is easy to scratch, the opening and closing time is longer, the shape and weight of the gate valve are large
Gate valves are widely used in pipes and are suitable for manufacturing large-diameter valves. Gate valves are usually used to cut off fluid and should not be used to regulate flow.
1. Compact structure, reasonable design, good rigidity, smooth passage, small flow coefficient.
2. Sealing surface is made of stainless steel and cemented carbide with long service life.
3. Manual drive mode.
4. Novel design, reasonable, reliable sealing, light and flexible operation.
5. Suitable materials are used to meet the temperature of different medium.

Electric gate valve
Features and uses of electric gate valve:
Driving part of the product adopts multi-rotary electric actuator to drive and control the opening and closing of the valve. The operator can remote control the valve inside a control room or manually operate the valve on site. Also can cooperate with the computer to realize the computer automatic control. The valves are widely used in drainage, heating, power plant, chemical, food, paper, pharmaceutical, coal, mining industries, meeting the automation requirements of modern industry and agriculture.
Electric gate valve is a straight line operation valve, it is compatible with the Z type multi-rotary actuator and have switch type and intelligent type
The valve is very simple to operate and is one of the most common opening and closing valves, which use Up and down operation of the gate to connect and close the fluid medium in the pipeline. Optional electrical controller
Characteristics of electric double flange gate valve
1. Fast opening and closing, stable and reliable, high degree of automation.
2. Installation height and position are not limited.
3. Adopting explosion-proof electric device can work normally in flammable and explosive, even poisonous gas environment.
4. Equipped with manual operation unit, in case of power interruption, manually operate to open or close valves for effective control of medium to prevent accidents
