At Smart Products USA, our team has been crafting components for over 40 years, creating millions of possible configurations for our check valves. One of our options is our line of spring-loaded check valves which have applications in diverse fields. Read on to learn about these quality components and everything Smart Products can supply for your operations.

What Are Spring-Loaded Check Valves?

Spring-loaded check valves get their name from their spring-based functionality, the “mechanism of action” that causes the valve to open and close or operate, in other words. No other components of the valve can move unless the spring moves.

Spring-loaded check valves must have a force (liquid or air/gas) acting against them so that their springs operate properly. This means the springs contract in order to allow flow through the valve, and the springs expand to restrict the flow when force is decreased. This back-and-forth action, supplying pressure relief/pressure restriction, makes up the essential functions of spring-loaded check valves.

Applications and Industries Ideal for Spring-Loaded Check Valves

Applications that are more likely to use spring-loaded check valves are those that involve the movement of liquid or air/gases through a system. In these types of applications, which are found in a wide range industries, there is a point or points in the system that require the restriction or stoppage of flow in the opposite direction or the relief of pressure.

This can be seen in a medical device that requires a spring-loaded check valve for open/close functionality for air or fluids, an automotive application that requires pressure relief at certain points as pressure builds, or countless other possibilities.

Relevant Environments for These Check Valves

A spring-loaded check valve is best suited for applications that require precise opening and closing pressures, as the need for precision is key in such cases. A simple ball or flap valve responds to pressure placed against it, but a spring-loaded check valve only begins to open at a precise pressure.
