Jan 15, 2024 · A check valve, also known as a non-return or one-way valve, is a two-port safety device that allows gas, steam, or fluid to flow in a single direction. Its primary purpose is to restrict backflow in a system. There are a variety of check valve stopping mechanisms, including a …

Fortunately, an inline check valve can be ordered and designed for a specific application, and the cracking pressure can be matched to the needs of a system. A special feature of an inline check valve is the spring that will lift when there is pressure on the side of the valve facing upstream.

Apr 16, 2019 · They are designed to allow flow in one direction while blocking flow in the opposing direction — that’s it. Some valves get more complicated, such as the pilot-operated check valve, but the one most commonly used as a supplemental component to a fluid power system is the inline check valve.

Nov 28, 2018 · Fig.1: A typical in-line check valve showing orientation with an arrow. Check valves are devices that only allow media to flow in one direction. Due to this, they are often called “one-way” or “non-return” valves. They are two-port …

Aug 18, 2024 · Inline spring-loaded check valves: These valves use a spring mechanism to assist in closing. The spring ensures a quick response to changes in flow direction, minimizing backflow risk. They are compact, can be installed in any orientation, and are suitable for systems with low-pressure differentials.

Aug 13, 2023 · Inline check valves (Globe-Style Sliding Disc Check Valve): These valves are installed within the piping system and use a spring-loaded disc to allow fluid to flow in one direction and prevent backflow when fluid flows in the opposite direction.

Aug 2, 2022 · Spring-loaded inline valves can also be called nozzle or silent check valves. These valves require an inlet pressure high enough to overcome the cracking pressure and spring force for the valve’s orifice to open and allow fluid flow.

Aug 28, 2020 · A Check valve is a mechanical device used in piping and pipeline systems to prevent back-flow. Check valves allow fluid flow only in the forward direction that’s why it is called a one-way valve or non-return valve. They work on the principle of differential pressure.

Function of Check Valve. The working of the check valve mainly depends upon the pressure difference between outlet and inlet port. When the pressure at inlet side is high, the valve opens the passage for fluid to flow.

Inline check valves utilize a check mechanism that functions in the fluid line or media pathway of a process piping system. Oftentimes, these check valves are of a compact design allowing for space saving and/or ease of installation into an existing system.
