Ductile Iron Water Seal Thread Gate Valve PN16
A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The gate faces can be parallel but are most commonly wedge-shaped (in order to be able to apply pressure on the sealing surface).
Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance.
Gate Valve Applications
- Gate valves are used in almost all fluid services such as air, fuel gas, feedwater, steam, lube oil, hydrocarbon, and all most any services.
- Some special gate valve is used in slurry and powder product also such as knife gate valve
Advantages of Gate Valve
- Gate valve provides good pressure drop during operation
- Most of the gate valve can be used as bi-directional
- They are suitable for high pressure and temperature application and required less maintenance
