Check valves, or one-way valves, are designed to stop backflow and, ultimately, to protect pumps and compressors.They are available in several styles and sizes, from 18 inch to as large as may be required.Check valves are found in many industries and with various applications ranging from municipal water to mining and natural gas.
Check valves get your backflow in check when a check valve is needed to prevent backflow, nibco has a complete line-up, including the nibco ring check with self-closing disc, horizontal swing, sliding disc, silent check and y pattern.
The new style 711731 check valves allow the valves to be installed without any costly and labor-intensive changes to the existing structure.The 711731 is engineered to crack open at 1-2 of head pressure and with its unique engineered sloping bottom, the valve ensures zero potential for standing water.
Check non-return valves are installed in pipelines to allow flow in one direction only helping to protect equipment and processes.Find out about the operation, benefits, applications and selection of different designs, including lift, disc, swing and wafer check valves.

A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which allows fluid to flow through it in only one direction.There are various types of check valves used in a wide variety of applications.Check valves are available in a wide range of sizes and costs, check valves generally are small, simple, andor inexpensive.
A check valve ensures that water only flows in a single direction of a plumbing system.This prevents contaminated water from flowing back into the system once it has been used.There are various types of check valves including swing, spring-loaded, and in-line check valves.
Check valves prevent backflow into sump disposal lines, wastewater lines, sewage lift stations, and ejector systems.They are used in combination with piston, diaphragm and metering pumps and commonly use ball check valves that combine balls and seats.
Check valve maverick valves mvmck5075 check valve is often used in the oilfield when drilling, lift check valve is designed and manufactured in accordance with api 6a.The api 6a check valve incorporates a metal-to-metal seal for high pressure, high-temperature environments where elastomer seals cannot be used.Primary applications for the check valve are high-pressure.
These valves can be installed in horizontal and vertical lines.The ball check valve is one of the few check valves that works well in both water and wastewater applications.Ball check valves are simple in operation and commonly used on small pumps and in low head systems.
Conditions controlled by your check valve.Along with holding water pressure in your system, your check valve assists in the smooth and safe operation of your water system by extending its life and preventing backspin, up-thrust and water hammer.Here are a few conditions check valves.
