Forged Gate Valve, which is also known as knife valve or slide, is basically used to control the flow of water or any kind of liquid through a pipe or duct. When these valves are turned a closure element moves up and down to obstruct the flow of liquid. It is widely used in many places including homes, factories, large industries, hotels and so forth.Due to the widespread uses and advantages of gate valve, it can be found in different varieties to suit the different requirements. Some of the most popular varieties include the following.
These valves control the flow of liquid by utilising a flat disc that is placed between two parallel seats. These two seats are placed in an upstream and downstream manner. This can be used effectively to control the flow of water.This is the most common variety of valve used in most of the areas today. It has a round handle which is attached to a shaft or stem. This shaft rises as the handle is turned, to open the valve. The shaft comes down when the valve is closed. Though it is one of the most popular types of valves, it cannot be used in areas where there is space constraint.
This gate valve is popularly used for underground pipes where it is difficult for the shaft to raise. The valve can be opened by rotating the handle to the left and closed by rotating it fully to the right. It is quite easy to padlock the non-rising stem valves compared to the rising stem valves. The non-rising stem valves require only one paddock unlike the rising stem globe valves manufacturers which require two paddocks.
