Check Valve With Flange Connection | Hongfute Valve Group Co., Ltd

Check Valve With Flange Connection

Flange connected check valve, stable connection, easy installation and disassembly, can adapt to pipes of different diameters. As an automatic valve, it can automatically open and close under the medium Pressure without additional power to prevent the medium from flowing back. Reliable sealing performance, multiple sealing materials are suitable for different media, such as rubber for water and other media, and hard alloy for high temperature and high pressure, particle containing media. Various Material, such as cast iron, cast steel and stainless steel, can meet the strength and corrosion resistance requirements of different working conditions. But when the medium flow rate is low, the sealing effect may be affected and it is not suitable for frequent and rapid opening and closing situations.

Efficient regulation of various fluid media

Fluorine Lined Globe Valve

1. The valve body is lined with fluorine material, which is resistant to strong corrosive media such as strong acids and alkalis; 2. The cut-off seal is tight and the interception effect is good; 3. Smooth opening and closing, high adjustment accuracy; 4. The structure is adaptable to various pipelines, easy to maintain, and suitable for corrosive working conditions.

Fluorine Lined Gate Valve

1. F46 lining is resistant to strong corrosion, and the gate is sealed and leak proof; 2. Fully open the flow channel smoothly without any obstruction, and ensure smooth opening and closing; 3. Simple structure, easy maintenance, suitable for transporting corrosive media.

Fluorine Lined Clamp Butterfly Valve

1. F46 lining is resistant to strong corrosion, and the clamp connection is lightweight and space saving; 2. Fast opening and closing at 90 °, low flow resistance, and zero leakage in four stage sealing; 3. Adjustable, easy to maintain, and adaptable to multiple working conditions.

Diaphragm Valve

API American Standard Fluorine Lined Ball Valve

1. Fluorine lined (PTFE/F46) is resistant to strong corrosion, meets API standards, and has strong adaptability. two Floating ball structure, sealed with zero leakage, quick opening and closing at 90 °. three The integrated golf club is safer, with low flow resistance and easy maintenance.

Fluorine Lined Electric Flange Gate Valve

Fluorine lined electric flange gate valve combines corrosion resistance and automation control advantages. With fluoroplastic lining, it has excellent resistance to strong corrosive media such as strong acids and alkalis, and is suitable for harsh environments such as chemical and pharmaceutical industries. Adopting flange connection, easy installation and maintenance, adaptable to different pipelines. Electric drive enables remote control, improving operational convenience and automation level. Good sealing performance, capable of effectively cutting off media. However, due to the limitations of fluorine lining materials, the working temperature range is limited, and compared to ordinary gate valves, the cost is higher. When installing and using, attention should be paid to avoiding collision damage to the lining layer.
