CHECK |
| Check valves are used to prevent the back-flow in a pipeline. Offers quick automatic reaction to flow changes. The pressure of flowing fluid keeps the valve open, and any reversal of flow closes it. They are also used as a safety device to protect equipment, product, and human lives. | |
 |
GLOBE |
| Globe valves are used to regulate or throttle fluid flow from none to full capacity. The change in direction of fluid flow through the valve produces increased resistance and considerable pressure drop in globe valves. | |
 |
GATE |
| Gate valves are designed to ensure a straight line flow and to reduce to a minimum the pressure drop due to friction. Should be used in liquid lines, pump lines, and main supply lines where unrestricted flow is desired. Not recommended for throttling applications. |
