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, tapi kami pasti akan menjadi produsen paling jujur dan mitra paling setia Anda.

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, kebocoran, or even system failure.
- Maintaining System Pressure: Some pipeline systems, check valves are used to maintain the desired pressure levels. Misalnya, 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.
Katup Periksa Ayun
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, piringan bergerak ke atas dan ke bawah untuk membuka dan menutup katup. 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, pembangkit listrik, pertambangan, and petrochemical industry applications to prevent backflow of fluids or gases and protect the equipment from damage.
Katup Periksa Wafer
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, farmasi, environmental protection, pembuatan kertas, pertambangan, urban construction, household pipeline and other industries.
Katup Periksa Bola
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, bola ditekan ke dudukan katup, preventing backflow. Ball check valves are suitable for applications with high flow rates and where minimal pressure drop is required.
Hentikan Katup Periksa
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.
Namun, 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.
Katup Periksa Senyap
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, termasuk minyak dan gas, bahan kimia, petrokimia, farmasi, makanan dan minuman, dan pengolahan air. These valves can be used in a variety of applications, such as pipelines, pompa, and compressors, to prevent backflow and protect equipment.
The Most Important Applications and Uses of Check Valves
Proyek Pengolahan Air
Swing check valves are commonly used in water treatment plants to prevent backflow and protect pumps. According to Farpro's statistics, ditemukan bahwa berbagai jenis katup digunakan untuk setiap tingkat pengolahan air limbah secara umum.
1. langkah pertama, pengobatan primer, menghilangkan polutan padat dalam suspensi, dan sebagian besar metode pengobatan fisik memenuhi persyaratan pengobatan. Setelah perawatan primer, tingkat penghapusan BOD umumnya sekitar 30%. Di sini katup dan aksesori pipa yang umum digunakan: katup gerbang pisau, katup kupu-kupu eksentrik rangkap tiga, filter, dll..
2. langkah kedua, kebutuhan untuk menghilangkan polutan organik koloid dan terlarut dalam limbah (BOD, zat COD), tingkat penghapusan 90%, sehingga polutan organik memenuhi standar pembuangan, tingkat penghilangan materi tersuspensi menjadi 95%. Katup yang biasa digunakan di sini adalah katup kupu-kupu segel lunak, katup gerbang, katup bola, katup periksa, dll..
3. langkah ketiga, metode utamanya meliputi denitrifikasi biologis dan penghilangan fosfor, koagulasi dan sedimentasi, penyaringan pasir, adsorpsi karbon aktif, pertukaran ion dan elektroosmosis. Katup yang dibutuhkan disini adalah katup kupu-kupu, gerbang katup, katup bola, katup periksa, sambungan karet lunak, dll..
Industri Pembangkit Listrik
Farpro percaya bahwa aplikasi pembangkit listrik menyebabkan tekanan yang sangat besar pada pipa dan katup, jadi katup memerlukan bahan dan desain yang kuat untuk menangani berbagai pengujian sirkulasi, suhu dan tekanan.
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.
Selain katup uap utama, pembangkit listrik memiliki banyak jaringan pipa tambahan. Saluran pipa bantu ini terdiri dari berbagai macam katup globe, Katup kupu-kupu, katup periksa, katup bola, dan katup gerbang.
Pengolahan Kimia
Ball check valves are commonly used in chemical processing applications, where the flow rate is high, and pressure drop is minimal.
Oil & Gas / Industri Kelautan
Farpro telah menyimpulkan, berdasarkan penjualan dan data global, bahwa permintaan katup pada industri ekstraksi minyak dan gas serta industri transportasi global terus meningkat. Permintaan ini mendorong industri minyak dan gas mencari jaringan pipa pengeboran yang lebih dalam dan biaya produksi yang lebih rendah, jadi teknisi lebih berhati-hati dalam memilih peralatan dan perangkat keras katup yang berkualitas.
Diaphragm check valves are suitable for the oil and gas industry, where the fluid may contain debris, and low pressure drop is required.
