We are a check valve manufacturing company who specializes in miniature spring loaded stainless steel check valves. We provide many different check valve types; inline check valves, hose check valves, NPT check valves, and gland check valves. All our check valves can be ordered with a custom low opening pressure to suit your needs or can also be used as a relief valve. We CNC machine all our valve components to eliminate the sources of leakage that occur in plastic injection molded check valves. We can also machine check valves in a variety of materials to meet your specific needs such as brass, Delrin, aluminum, and other materials. If you need us to modify one of our existing valves or create a custom liquid or air check valve for your application, just ask. Remember us WHEN IT NEEDS TO BE RIGHT!
