Many types of check valve can be made from different materials, such as brass check valve, stainless steel check valve, PVC check valve, and cast iron check valve, depending on the application and the fluid or gas properties.
They also known as non-return valves or one-way valves, are mechanical valves that allow the fluid or gas to flow in one direction and prevent backflow. This type have a disc or a ball that rests on a seat, which closes the valve when the flow stops or reverses direction.
Farpro Valve manufacturers offer a wide range of general-purpose check valves and most specialty non-return valves to many industries and businesses. We guarantee the best quality of check valve products while keeping the sales price as low as possible.

Advantages of Check Valves
- Preventing Backflow: The primary advantage of non-ruturn check valves is that they prevent backflow, which can cause damage to equipment and disrupt the flow of fluid in a system. By preventing backflow, check valves help to maintain system efficiency and prevent costly downtime.
- Reduced Maintenance: Check valves require little maintenance compared to other types of one-way valves. They are typically designed to operate without any external power source, making them easy to install and maintain.
- Energy Savings: Check valves can help to reduce energy consumption in a system. By preventing backflow, check valves reduce the need for additional pumping power to compensate for the loss of pressure caused by reverse flow. This can result in significant energy savings over time.
- Improved System Efficiency: Types of check valves can improve the overall efficiency of a system by maintaining a consistent flow of fluid in one direction. This can help to reduce the wear and tear on equipment and improve the performance of pumps and compressors.
- Preventing Water Hammer: Pipelines carrying liquids, such as water distribution systems, rapid changes in flow velocity can cause pressure surges known as water hammer. Check valves help mitigate the effects of water hammer by preventing the sudden reversal of flow, which can lead to pipe damage, leaks, or even system failure.
- Maintaining System Pressure: Some pipeline systems, check valves are used to maintain the desired pressure levels. Bijvoorbeeld, in water distribution networks, check valves can prevent the backflow of water from higher-pressure areas to lower-pressure areas, ensuring consistent water pressure throughout the system.
- Preventing Backflow of Hazardous Materials: Pipelines carrying hazardous materials, such as chemicals or toxic gases, check valves are essential for preventing backflow and potential leaks or spills that could pose environmental or safety risks.
Terugslagklep
Swing check valves are the most common type of check valves. They consist of a disk that swings on a hinge, allowing the fluid to flow in one direction and closing when the fluid flows in the opposite direction.
Swing check valves are suitable for applications with low to moderate flow rates, and where back pressure is minimal.
Lift / Piston Check Valve
Lift/Piston check valves are similar to swing check valves, but instead of swinging, the disk moves up and down to open and close the valve. Lift check valves are suitable for high-pressure applications and where the flow rate is low to moderate.
Piston check valves are commonly used in oil and gas pipelines, stroomopwekking, mijnbouw, and petrochemical industry applications to prevent backflow of fluids or gases and protect the equipment from damage.
Wafer-terugslagklep
The wafer check valve is thin and structurally stable, so it can be adapted to a wide range of scenarios.
This type check valve is widely used in roommate chemical, metallurgical manufacturing, farmaceutisch, environmental protection, papier maken, mijnbouw, urban construction, household pipeline and other industries.
Bal terugslagklep
Ball check valves use a ball-shaped disk to control the flow of fluid. When the fluid flows in the desired direction, the ball moves away from the valve seat, allowing the fluid to pass through.
When the fluid flows in the opposite direction, the ball is pressed against the valve seat, het voorkomen van terugstroming. Ball check valves are suitable for applications with high flow rates and where minimal pressure drop is required.
Stop de terugslagklep
Stop check valves combine the features of a lift check valve and a globe valve. They allow fluid to flow in one direction and close to prevent backflow.
Echter, they also allow the operator to manually close the valve in the event of an emergency or maintenance. Stop check valves are suitable for high-pressure applications and where frequent maintenance is required.
Stille terugslagklep
A silent check valve is a type of valve that is designed to prevent backflow in a piping system. The valve body is usually made of metal or plastic and contains the other components of the valve. The nozzle is a small opening in the valve body that allows fluid to flow through. The check valve element is located inside the valve body and is designed to allow fluid to flow in one direction only.
The scope of application of a nozzle check valve can be in a wide range of industries, inclusief olie en gas, chemisch, petrochemisch, farmaceutisch, food and beverage, en waterbehandeling. These valves can be used in a variety of applications, such as pipelines, pumps, and compressors, to prevent backflow and protect equipment.
The Most Important Applications and Uses of Check Valves
Waterzuiveringsproject
Swing check valves are commonly used in water treatment plants to prevent backflow and protect pumps. According to Farpro's statistics, het bleek dat er voor elk niveau van de algemene afvalwaterzuivering verschillende soorten kleppen worden gebruikt.
1. De eerste stap, primaire behandeling, verwijdert vaste verontreinigende stoffen in suspensie, en de meeste fysieke behandelmethoden voldoen aan de eisen van de behandeling. Na de primaire behandeling, het verwijderingspercentage van BZV ligt over het algemeen rond 30%. Here commonly used valves and pipeline accessories are: mesafsluiters, triple eccentric butterfly valves, filters, enz.
2. the second step, de noodzaak om de colloïdale en opgeloste organische verontreinigende stoffen in het rioolwater te verwijderen (BOD, CZV-stoffen), het verwijderingspercentage van 90%, zodat organische verontreinigingen voldoen aan de lozingsnormen, verwijderingspercentage zwevende stoffen tot 95%. The valves commonly used here are soft seal butterfly valves, schuifafsluiters, kogelkranen, terugslagkleppen, enz.
3. the third step, de belangrijkste methoden zijn biologische denitrificatie en fosforverwijdering, coagulatie en sedimentatie, zandfiltratie, adsorptie van actieve kool, ionenuitwisseling en elektro-osmose. De kleppen die hier nodig zijn, zijn vlinderkleppen, poort Sluis, kogelkraan, terugslagklep, rubberen zachte verbinding, enz.
Energieopwekkingsindustrie
Farpro believes that power plant applications put piping and valves under tremendous stress, Kleppen hebben dus robuuste materialen en ontwerpen nodig om de vele circulatietests aan te kunnen, temperatuur en druk.
Stop check valves are commonly used in power generation applications, where high-pressure steam and fluid must be controlled to ensure safety and prevent damage to equipment.
Naast de belangrijkste stoomkleppen, energiecentrales hebben veel hulppijpleidingen. Deze hulpleidingen bestaan uit een grote verscheidenheid aan klepafsluiters, vlinderkleppen, terugslagkleppen, kogelkranen, en schuifafsluiters.
Chemische verwerking
Ball check valves are commonly used in chemical processing applications, where the flow rate is high, and pressure drop is minimal.
Oil & Gas / Maritieme industrie
Farpro heeft besloten, gebaseerd op wereldwijde verkopen en gegevens, dat de vraag naar kleppen in de mondiale olie- en gaswinningsindustrie en de transportsector blijft groeien. Deze vraag heeft geleid tot de zoektocht van de olie- en gasindustrie naar diepere boorpijpleidingen en lagere productiekosten, Daarom besteden technici meer zorg aan het selecteren van hoogwaardige klepapparatuur en hardware.
Diaphragm check valves are suitable for the oil and gas industry, where the fluid may contain debris, and low pressure drop is required.
