Selecting the Right Gate Valves
As a China Gate Valve manufacture,I will share it with you.
The most popular style of valve in the world of flow control is the gate valve. They are the on/off switches of the fluid control industry and they are found in every refinery, chemical plant, power plant and industrial facility. Gate valves exist for one primary purpose- to stop flow. The chief advantage of a gate valve is that it offers virtually no resistance to flow in the open position.
Positives for gate valves:
When fully open, there is low resistance to fluid flow. The opening in the valve tends to mimic the cross sectional characteristics of connected piping and fluid can flow through the valve without a directional change.
Changing the gate position (opening or closing the valve) does not require as much force or power as some other valve types, due to the gate movement being perpendicular to the flow direction.
Gate valves work in both directions. The flow in the connected line can be reversed and the valve function is unimpaired.
The gate valve assembly tends to be shorter in length along the path of flow than some other designs.The rate of closure is generally slow, providing a graduated reduction in fluid movement and reduced physical shock to the piping system.
