Introduction of the Characteristics of Threaded Gate Valve

Threaded gate valve has the following advantages:

1. The structure is simple. It’s convenient to manufacture and maintain it.

2. The working stroke is small. The opening and closing period is short.

3. The sealing performance is good. The friction between sealing surfaces is small. The service life is long.

Threaded gate valve has the following disadvantages:

1. The fluid resistance is large. The force needed during opening and closing is relatively large.

2. It’s not suitable for medium that has particles and large viscosity, and is easy to coke.

3. The regulating performance is poor.

According to the position of sanitary valve stem thread, threaded gate valve can be divided into external thread type and internal thread type. According to the flow direction of the medium, it can be divided into straight-through type, direct flow type and angled type. According to the sealing types, there are stuffed bellows gate valve and bellows sealed shut-off valve.
