Many types of check valve can be made from different materials, pirinç çek valf gibi, paslanmaz çelik çek valf, 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, ama kesinlikle en dürüst üretici ve en sadık ortağınız olacağız.

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. Örneğin, 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.
Salıncak Çek Valfı
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, güç üretimi, madencilik, and petrochemical industry applications to prevent backflow of fluids or gases and protect the equipment from damage.
Gofret Çek Valf
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, eczacılığa ait, environmental protection, paper making, madencilik, urban construction, household pipeline and other industries.
Küresel Çek Valf
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.
Çek Valf Durdurma
Stop check valves combine the features of a lift check valve and a globe valve. Sıvının tek yönde akmasına ve geri akışı önlemek için kapanmasına izin verirler.
Fakat, 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.
Sessiz Çek Valf
A silent check valve is a type of valve that is designed to prevent backflow in a piping system. Valf gövdesi genellikle metal veya plastikten yapılır ve valfin diğer bileşenlerini içerir.. Meme, valf gövdesinde sıvının akmasına izin veren küçük bir açıklıktır.. Çek valf elemanı, valf gövdesinin içinde bulunur ve sıvının yalnızca tek yönde akmasına izin verecek şekilde tasarlanmıştır..
Nozül çek valfinin uygulama kapsamı çok çeşitli endüstrilerde olabilir, petrol ve gaz dahil, kimyasal, petrokimya, eczacılığa ait, yiyecek ve içecek, ve su arıtma. Bu vanalar çeşitli uygulamalarda kullanılabilir, boru hatları gibi, pompalar, ve kompresörler, geri akışı önlemek ve ekipmanı korumak için.
