Detailed introduction of soft sealing butterfly valve-(2)

There are many types of soft-sealed butterfly valves, which can be divided into the following categories according to different forms: Classified by structure Classified by structure (1) Center sealing butterfly valve (2) Single eccentric sealed coal valve (3) Double eccentric sealing butterfly valve (4) Triple eccentric seal valve Classified according to the sealing surface material: […]

Detailed introduction of soft sealing butterfly valve-(1)

The butterfly plate of the soft sealing butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened. The […]

Difference between Soft seal gate valve and hard seal gate valve

Soft seal gate valve and hard seal gate valve are two major categories in the gate valve series. Hard seal and soft seal can sometimes compensate for each other, and sometimes they are independent of each other. So what is the relationship between soft seal gate valve and hard seal gate valve? What are the […]

Difference between soft seal butterfly valve and hard seal butterfly valve

The difference between soft seal butterfly valve and hard seal butterfly valve: A butterfly valve hard seal refers to a “hard seal” in which both sides of the seal pair are made of metal materials or other harder materials. This kind of seal has poor sealing performance, but high temperature resistance, wear resistance, and good […]

Triple eccentric multi-level hard sealing flange butterfly valve

The triple eccentric multi-level hard-sealed flange butterfly valve is a valve designed with the principle of three-dimensional knitting. The product is composed of main components such as valve body, butterfly plate, multi-level valve seat, valve stem, and transmission mechanism. It is widely used in the pipelines of corrosive media such as metallurgy, electric power, petroleum, […]

Installation instructions of double eccentric butterfly valve

Installation instructions of double eccentric butterfly valve: 1. Before installation, you must carefully check whether the valve’s mark and certificate of conformity meet the requirements for use, and clean it after verification. Uninstalled valves should be stored in a dry room. Valves stored for a long time should be cleaned regularly, dried and coated with […]

Classification and features of Eccentric butterfly valves

Eccentric butterfly valves are divided into single eccentric butterfly valves, double eccentric butterfly valves, triple eccentric butterfly valves, and variable eccentric butterfly valves. Contrast with concentric butterfly valve. A butterfly valve whose stem axis deviates from the center of the disc and the center of the body at the same time, and the sealing pair […]

Features and application area of double eccentric butterfly valve

Double eccentric butterfly valve is also called high-performance butterfly valve. It is mainly used for drainage of water plants, power plants, steel smelting, chemical industry, water source engineering, environmental facility construction, etc. It is especially suitable for water pipelines and used as regulation and interception equipment. Compared with the centerline butterfly valve, the double eccentric […]

Centerline flange butterfly valve

The centerline flange butterfly valve is a high-quality soft-sealed valve. Mainly by the fully lined rubber valve body. The disc plate, valve stem, operating mechanism and other parts have the characteristics of simple structure, good corrosion resistance, light operating torque and high reliability. Overview of Centerline flange butterfly valve: The centerline flange butterfly valve is […]

Related Information of flange butterfly valve

Valves with metal seals generally have a longer life than valves with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the defect of being limited by temperature. If the butterfly valve is required to be used as a flow control, […]
