Valves are essential components in gas projects as they control the flow and pressure of gases within pipelines and systems. There are several types of valves commonly used in gas applications, including:
Gate Valves
These are used for on/off control. They provide minimal pressure drop and are best for applications where the valve is either fully open or fully closed.
Ball Valves
Known for their quick operation, ball valves can be opened or closed with a quarter turn. They are reliable and provide a tight seal, making them ideal for gas applications.
Globe Valves
These are used for regulating flow. They have a spherical body and are effective in controlling flow rates but can create more pressure drop compared to gate or ball valves.
Check Valves
These prevent backflow in the system. They allow gas to flow in one direction only, which is crucial for maintaining system integrity.
Safety Valves
These are critical for protecting the system from overpressure by automatically releasing gas if pressure exceeds a predetermined limit.
Each type of valve has specific applications and advantages, depending on the requirements of the gas project.
