Introduction
What Are Valves?
Valves are mechanical devices used to regulate, direct, or control the flow of liquids, gases, slurries, or other substances within piping systems. They play a critical role in managing the flow, pressure, and direction of various media, ensuring the smooth functioning of industrial operations.
Valves are essential components in various industries, playing a crucial role in controlling the flow of fluids and gases. From simple on-off operations to precise flow regulation, valves ensure the smooth functioning of systems across diverse sectors. Different types of valves serve specific purposes, each with its unique design and operation.

Key Specifications of Valves
When selecting a valve, several factors need to be considered:
- Material: The valve material should be compatible with the fluid being handled, considering factors like corrosion resistance and temperature.
- Pressure Rating: The valve must be capable of withstanding the maximum pressure of the system.
- Temperature Rating: The valve should be suitable for the operating temperature range.
- Flow Capacity: The valve must have sufficient capacity to handle the required flow rate.
- End Connections: The type of connection (flanged, threaded, or welded) should match the piping system.
- Valve Size: The valve size should be appropriate for the application.
Understanding valve specifications ensures the right fit for applications:
| Valve Type | Key Considerations |
| Manifold Valve | Material type, flow capacity, pressure rating. |
| Needle Valve | Thread type, maximum operating pressure, precision flow control. |
| Ball Valve | Seat material, body design, flow coefficient. |
