Short Article on Valve Functions

1. Blocking Flow

Blocking flow valves are designed to completely stop the flow of fluid through a pipe. They are typically used in situations where it is necessary to isolate a section of a system for maintenance or to prevent the flow of fluid in an emergency. Blocking flow valves are often used in conjunction with other valves, such as throttling valves, to control the flow of fluid in a system.

2. Throttling Flow

Throttling valves are designed to control the flow of fluid through a pipe by varying the size of the opening in the valve. They are typically used in situations where it is necessary to regulate the flow of fluid to a specific rate or to maintain a specific pressure in a system. Throttling valves are often used in conjunction with other valves, such as blocking flow valves, to control the flow of fluid in a system.

3. Preventing Flow Reversal

Non-return valves, also known as check valves, are designed to prevent fluid from flowing in the opposite direction. They are typically used in situations where it is necessary to protect a pump or compressor from damage due to reverse flow, or to prevent backflow into the upstream part of a system due to process reasons. Non-return valves are often used in conjunction with other valves, such as blocking flow valves and throttling valves, to control the flow of fluid in a system.
