Check Valve


A check valve is a device that only allows the flow of fluids in one direction. They have two ports, an inlet and the output.  When the pressure is higher on the outlet side (or the input side pressure is not high enough), the valve will close. Unlike other valves, they do not need a handle, lever, actuator, or human to correctly work.  Commonly referred to as ‘one-way valves’ or ‘non return valves,’ the main purpose of a check valve is to prevent contaminated backflow into the system.  Our quality check valves are an economical, effective, and easy solution to solve a potential issue in many applications.

To provide our customers with the options they need, our check valves are available in T316 stainless steel and brass. We also offer additional savings and discounted prices for repeat customers and bulk orders.  Our goal is to provide reliable products and unparalleled customer service.
