Springs for Valves

Definition:

Coil compression springs which are installed inside a device for managing the travel of a substance (liquid or gas). Valves apply and release pressure.

Get your springs for valves at China Spring Products Corp! We have over 30 years of experience in the spring industry as well as the best spring technology online. No only are we able to manufacture your coil compression springs for valves, but we’re able to help you design it so that you’re sure that they will work accordingly inside of the valve.

Valves must either carry or release pressure. This means that, in order for your valve to work, it must be strong to withstand the pressure or load, yet flexible to be able to deflect and compress when it is needed to. At China Spring Products Corp we can help you make sure your spring works inside your valve. Using our free online spring calculator, we’re able to generate a design and find out whether your spring will have enough elasticity to meet your desired loaded height or distance traveled. We can also figure out if the spring will be strong enough to hold the load and not take a permanent set. By combining both of these factors, we’ll be able to know your spring’s constant rate of pounds (newtons) per inch (millimeter) of distance traveled.

For liquid and air valves, you might want to use stainless steel so that your spring will not rust. On springs for liquid valves, you are faced with a moist environment and in the case of an air valve you are faced with condensation which is a sort of fog also made from moisture. Your springs for valves may also be in a place where they will have to resist very high temperatures. In these cases, stainless steel is also a great option. The types of stainless steel we carry at China Spring Products Corp for your valve springs’ manufacturing are Stainless Steel 302 A313, Stainless Steel 17-7 A313, and Stainless Steel 316 A316. To check the properties of our stainless steel material types, please visit our Properties of Common Spring Materials page under the Tech Info tab on our website.

The physical dimensions and measurements of your springs for valves are also important because the springs will usually be installed inside a confined space (hole) within your valve and might also go over a shaft or mandrel. In this case you must watch out for your valve spring’s inner and outer diameters. Make sure the inner and outer diameter aren’t either too tight or too loose around the walls of the hole (confined space) or shaft (mandrel).

Another important dimension is solid height. Solid height is the height of your compression springs for valves once they are fully compressed and all the coils are touching. This dimension also has a lot to do with your spring’s travel. If your spring’s solid height, is greater than your loaded height, your spring will not be able to travel or deflect enough.
