1-1/2" 200 PSI FNPT End Low Lead, Brass Gate Valve For Water, Oil Or Air
Introduction
Gate valve: refers to the valve that the closing part (gate) moves along the vertical direction of the channel axis.
It is mainly used for cutting medium on the pipeline. That is, fully open or fully closed. In general, gate valves cannot be
used for regulating flow rate. It can be used for low temperature low pressure or high temperature high pressure, and can
be used according to the different material of the valve. However, gate valves are generally not used for conveying mud
and other media in the pipeline.

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 is very less.
Most of the gate valve can be used as bi-directional
They are suitable for high pressure and temperature application and required less maintenance
