Tips: What is the difference between gate valve and globe valve?

• The structure is different, gate valve is more complex than globe valve, the height is larger, gate valve is shorter and higher than globe valve.
• Different sealing surface, gate valve in the opening and closing of the spool and seat sealing surface always contact and mutual friction, so the sealing surface is easy to wear, while the valve flap once in the opening condition, its sealing surface mechanical wear is smaller.
• Flow resistance is different, gate valve in the full open the entire flow channel straight, which is compared with the globe valve, it has the advantage of small fluid flow resistance, the flow resistance coefficient of ordinary gate valve is about 0.08 ~ 0.12, while the resistance coefficient of ordinary globe valve is about 3.5 ~ 4.5.
