The difference between fluorine-lined butterfly valve and metal butterfly valve

Butterfly valve is one of the most commonly used valves in industrial pipelines. It has a simple structure and is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. It is easy to operate and can be equipped with different driving devices, such as turbine devices, electric devices, […]

Precautions for debugging and installation of butterfly valves

Butterfly valve is one of the fastest-growing valve varieties at present. The application range of butterfly valves is very wide, and the varieties and specifications continue to expand, and they are developing in the direction of high pressure, large diameter, high sealing, long life, ultra-low temperature, and ultra-high temperature. Butterfly valves can do Emergency cutoff […]

Features of Stainless Steel Valves

Generally speaking, stainless steel valves are valves made of stainless steel. They are classified according to the stainless steel material grade of the valve body. They are mainly 301, 304, 316, 304L, 316L, etc. According to international standards, they can be divided into CF8, CF3, CF8M, CF3M, the quality of the material CF8<CF3<CF8M<CF3M. Because stainless […]

Maintenance Methods of Common Valves

Common valve failures include leakage, opening and closing parts damage and failure, etc. One of the most important reasons for the valve failure problem is that the valve is not well maintained. The valve is an important part of the pipeline transportation system. Maintenance and maintenance can make the valve better serve us. At the […]

What is the difference between butterfly valve and ball valve

What is the difference between butterfly valve and ball valve? The butterfly valve has a simple structure and a wider application range. The ball valve is only suitable for fluid medium pipelines without particulate impurities; the ball valve has better sealing performance and higher cost. In one sentence, the difference between butterfly valves and ball […]

Design Features of Electric Gate Valve

An electric gate valve is a gate valve that uses an electric actuator to control the opening and closing of the valve. Its structure can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the gate valve body. Connect the electric actuator and the gate […]

Precautions for butterfly valve maintenance

Butterfly valve is a kind of valve, it is a control component in fluid conveying system, it has the function of intercepting and adjusting the fluid flow of pipeline system. Butterfly valve is one of the most widely used valves, which can be used to control the flow of various types of fluids such as […]

Characteristics of soft seal /resilient seated gate valves

Title: what are the characteristics of soft seal /resilient seated gate valves? Traditional gate valves often have water leakage and corrosion. In order to overcome this shortcoming, the soft-seal gate valve appeared. As an updated product of the traditional gate valve, the soft-seal gate valve overcomes the shortcomings of poor sealing performance, poor elasticity, and […]

The Basic Knowledge of Butterfly Valves

Butterfly valve is also called butterfly type valve or flap valve, which is a kind of regulating valve with very simple structure. Its main structure is composed of valve body, butterfly plate, valve stem, valve seat, transmission device and operating mechanism. How does the butterfly valve work? The working principle of the butterfly valve is […]

The correct operation method of manual valve

The manual valve is operated by the operator with the help of a handle or a hand wheel to manipulate the opening and closing of the valve by manpower. When the valve opening and closing torque is large, a turbine device needs to be installed between the handle or hand wheel and the valve stem, […]
