The purpose of gate valve

Gate valve is a common type of valve with a wide range of applications, mainly reflected in the following aspects:
Basic functional purpose
Cut off fluid channel: Gate valves can completely prevent fluid flow in pipelines through the lifting and lowering of gate valves, achieving reliable cut-off function. They are suitable for situations where the pipeline needs to be completely closed for maintenance, equipment replacement, or process shutdown.
Regulating flow: Although gate valves are not an ideal choice specifically for flow regulation, to some extent, the fluid flow can be adjusted by controlling the opening height of the gate.
Preventing backflow: It can prevent fluid from flowing in the opposite direction in pipelines, protecting equipment and systems from damage caused by backflow.
Distribution of fluids: In complex pipeline systems, gate valves can be used to distribute fluids to different branch pipelines.
System isolation: In large industrial systems, gate valves can isolate different parts or equipment for separate operation, maintenance, or troubleshooting without affecting the operation of the entire system.
Daily life use
Control water flow: In the water pipe system of home decoration, gate valves can control the water flow in the house, adjust the direction of water flow, and can also be used to close or open the water pipes in the house. When the water pipe leaks or is damaged, closing the relevant gate valve can avoid causing greater losses and also save water resources.
Control heating: Installing heating at home usually requires installing gate valves to control the opening or closing of the heating system.
Industrial applications
Gate valves are widely used in industrial fields, including chemical, petroleum, natural gas, power, pharmaceutical, food processing, and other industries, to control the flow of fluids (liquids, gases, or vapors). For example, the stainless steel gate valve Z11W from Oram mainly serves the purpose of protecting the catalyst in catalytic devices.
