Definition - What does One-Way Valve mean?
One-Way Valve is a metal or plastic valve that allows fluids to flow in one direction but vitally closes to halt any backward motion. It is available in variant shapes and sizes and is inexpensive to install. The three most common designs of the One-Way Valve are bolted bonnet, threaded in bonnet and pressure seal bonnet. Moreover, it can also be fitted with a hydraulic cylinder for emergency support. Unlike other valves, it continues to work if the plant loses electricity, air or personnel who usually operate it.
Petropedia explains One-Way Valve
A One-Way Valve is installed in an oil production plant when there is a risk of condensate back flow. In the oil and gas industry, fluids are transported over diverse regions and at different temperatures. So as to fulfill the terms and conditions of each organization, the design of the One-Way Valve differs, i.e., it is available in ball, spring, lift and swing. Before the installation of the valve one must have knowledge of the valve performance, the size required and other piping requirements. An accurate One-Way Valve enhances optimal efficiency of the system and less maintenance is required.
