Question: 1 / 400

What type of valves are check valves classified as?

Pressure control valves

Flow control valves

Directional control valves

Check valves are classified as directional control valves because their primary function is to allow fluid to flow in one direction while preventing backflow. This ability to control the direction of flow is essential in many systems, where backflow could cause damage or inefficiency. Check valves operate automatically, with the flow direction determined by the pressure of the fluid. When the pressure on the upstream side of the valve is higher than the downstream side, the valve opens, permitting fluid flow. If the flow attempts to reverse, the valve closes, thus maintaining the intended direction of flow.

In contrast, pressure control valves are designed to maintain or limit pressure in a system, flow control valves adjust the flow rate, and bypass valves provide an alternative path for fluid during maintenance or system adjustments. Each of these types serves specific purposes that are distinct from the primary function of a check valve.
