| Gate Valve |
Used for on/off control of fluid flow. |
Water supply, oil and gas applications. |
Minimal pressure loss, reliable sealing. |
Not suitable for throttling, slower operation. |
| Ball Valve |
Uses a spherical disc to control flow. |
Gas and liquid services, HVAC systems. |
Quick to operate, good sealing properties. |
Not suitable for throttling in some sizes. |
| Check Valve |
Prevents backflow in piping systems. |
Water supply, sewage, drainage systems. |
Automatic operation, protects equipment. |
May create pressure loss, not always reliable. |
| Globe Valve |
Used for regulating flow in pipes. |
Water supply systems, fuel oil systems. |
Fine control, minimal noise during operation. |
Higher pressure drop, larger size needed. |
| Butterfly Valve |
Uses a rotating disc for flow control. |
Water treatment, chemical processes. |
Lightweight, low pressure drop. |
Less effective sealing compared to others. |
