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. Our Check valves do not necessarily have the lowest price, ale na pewno będziemy najbardziej uczciwym producentem i najwierniejszym partnerem.

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, przecieki, or even system failure.
- Maintaining System Pressure: Some pipeline systems, check valves are used to maintain the desired pressure levels. Na przykład, 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.

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, wytwarzanie energii, górnictwo, and petrochemical industry applications to prevent backflow of fluids or gases and protect the equipment from damage.

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, farmaceutyczny, environmental protection, paper making, górnictwo, urban construction, household pipeline and other industries.
Kulowy zawór zwrotny
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, preventing backflow. Ball check valves are suitable for applications with high flow rates and where minimal pressure drop is required.

Stop check valves combine the features of a lift check valve and a globe valve. Umożliwiają przepływ płynu w jednym kierunku i zamykają, aby zapobiec przepływowi wstecznemu.
Jednakże, 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.
Cichy zawór zwrotny
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, w tym ropę i gaz, chemiczny, petrochemiczny, farmaceutyczny, jedzenie i napoje, i uzdatniania wody. 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
Projekt uzdatniania wody
Swing check valves are commonly used in water treatment plants to prevent backflow and protect pumps. According to Farpro's statistics, stwierdzono, że dla każdego poziomu ogólnego oczyszczania ścieków stosowane są różne typy zaworów.
1. Pierwszy krok, leczenie podstawowe, usuwa zanieczyszczenia stałe z zawiesiny, a większość metod leczenia fizycznego spełnia wymagania leczenia. Po leczeniu podstawowym, wskaźnik usuwania BZT wynosi zazwyczaj około 30%. Here commonly used valves and pipeline accessories are: knife gate valves, triple eccentric butterfly valves, filters, itp.
2. the second step, konieczność usunięcia ze ścieków koloidu i rozpuszczonych zanieczyszczeń organicznych (BZT, Substancje ChZT), współczynnik usuwania 90%, tak, aby zanieczyszczenia organiczne spełniały normy dotyczące zrzutów, szybkość usuwania zawiesiny do 95%. The valves commonly used here are soft seal butterfly valves, gate valves, zawory kulowe, Sprawdź zawory, itp.
3. the third step, do głównych metod zalicza się biologiczną denitryfikację i usuwanie fosforu, koagulacja i sedymentacja, filtracja piaskowa, adsorpcja węgla aktywnego, wymiana jonowa i elektroosmoza. Zawory potrzebne tutaj to przepustnica, zasuwa, zawór kulowy, zawór zwrotny, gumowe miękkie złącze, itp.
Przemysł energetyczny
Farpro believes that power plant applications put piping and valves under tremendous stress, dlatego zawory wymagają solidnych materiałów i konstrukcji, aby wytrzymać wielokrotne testy cyrkulacji, temperatura i ciśnienie.
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.
Oprócz głównych zaworów parowych, elektrownie mają wiele rurociągów pomocniczych. Te rurociągi pomocnicze składają się z szerokiej gamy zaworów kulowych, zawory motylkowe, Sprawdź zawory, zawory kulowe, i zasuwy.
Przetwarzanie chemiczne
Ball check valves are commonly used in chemical processing applications, where the flow rate is high, and pressure drop is minimal.
Oil & Gas / Przemysł morski
Farpro doszedł do wniosku, na podstawie globalnej sprzedaży i danych, że zapotrzebowanie na zawory w światowym przemyśle wydobycia ropy i gazu oraz transporcie stale rośnie. Zapotrzebowanie to doprowadziło do poszukiwania przez przemysł naftowy i gazowy głębszych rurociągów wiertniczych i niższych kosztów produkcji, dlatego technicy przykładają większą wagę do wyboru wysokiej jakości wyposażenia i sprzętu zaworowego.
Diaphragm check valves are suitable for the oil and gas industry, where the fluid may contain debris, and low pressure drop is required.
