Description
Threaded forged steel gate valve is a kind of most common open/close valve. It is mainly composed of valve body, disc, bonnet, valve gland, gasket, bolt and nut. This threaded gate valve uses disc to connect or cut off medium in pipeline. Disc functions like a sluice gate to connect or cut off media, so it is called gate valve or sluice valve. The on-off component of gate valve is valve disc. The movement direction of disc is perpendicular to the flowing direction of fluid. Gate valve can only be opened or closed fully.
Applications
Forged steel threaded gate valve can be widely applied as fluid regulating and intercepting equipment in various pipelines, such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, and energy pipeline systems.
Classification
Threaded sluice valves can be classified according to fluid’s pressure grades into 900LB, 1500LB and 2500LB.
Features
1. Sealing material can be selected according to fluid so as to increase sealing property and wear resistance of the threaded gate valve and decrease cost.
2. Threaded forged steel gate valve needs small torsion to open.
3. Valve body adopts precision casting technique.
4. Numerical control processing is utilized on valve disc.
5. Valve seat is replaceable, which makes maintenance more simple and convenient.
6. Twice shot blasting processing on outer surface makes the threaded gate valve look fine and smooth.
7. Guarantee period of our products is 18 months. Lifelong technology service is offered.

Attentions When Selecting Forged Steel Threaded Gate Valves
1. Valve Form (Category, Structure and Connection Type)
2. Medium (Sluice Valve’s Material and Corrosivity)
3. Size of Diameter
4. Working Pressure (Intensity and Airtightness)
5. Working Temperature
Payment, Package and Delivery
1. Products can be paid by T/T, D/P, D/A, L/C or according to your requirement.
2. Threaded gate valves (threaded sluice valves) are packaged by standard exported wooden cases.
