Features and structure drawings of flange butterfly valve

The main features of  flange butterfly valve are: Small and light, easy to disassemble and repair, and can be installed in any position. The structure is simple and compact, the operating torque is small, and the 90° turn to open quickly. The flow characteristics tend to be straight, and the regulation performance is good. The […]

Introduction of Flange butterfly valve

The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. The butterfly plate of the butterfly valve […]

Pneumatic U-shaped flange butterfly valve

Introduction of Pneumatic U-shaped flange butterfly valve: The pneumatic U-shaped butterfly valve adopts a top-mounted structure, which reduces the connecting bolts of the valve body under the conditions of high pressure and large diameter, enhances the reliability of the valve and can overcome the influence of the weight of the system on the normal operation […]

structure and characteristics of U type flange butterfly valve

Introduction of U type flange butterfly valve: The face-to-face structure of U type flange butterfly valve is shorter than that of double flanged butterfly valve. U-shaped flange butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, food, medicine, textile, papermaking and other industries. It can be installed at a temperature of ≤425℃, and […]

The structure and application fields of the lug type butterfly valve

Product Introduction of lug type butterfly valve: The driving mode of the lug butterfly valve can be manual, worm gear, pneumatic, electric, hydraulic. The connection method can choose flange and wafer, the structure can choose single eccentric, center line, double eccentric, triple eccentric, and the sealing structure can choose soft seal or hard seal. The […]

Uses and characteristics of manual butterfly valve (2)

Uses/application of manual butterfly valve: Used in the gas pipeline in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the electric demisting series and the connecting valve, the inlet and outlet of the S02 main blower, the adjustment of […]

Uses and characteristics of manual butterfly valve (1)

The butterfly plate of the manual 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°-90°. When the rotation reaches 90°, the valve is fully opened. The butterfly valve is […]

Installation instructions of the wafer type butterfly valve

Preparation before installation of wafer type butterfly valve: 1. Check whether the specifications and materials of the butterfly valve conform to the design before installation. 2. Before installation, clean the internal sand, dust, foreign matter and debris to avoid irregular movement or leakage. 3. The related piping should be properly suspended and fixed according to […]

The structural characteristics and uses of the wafer butterfly valve

The structural characteristics and uses of the wafer type butterfly valve: The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve. The elastic seal is produced by torque. The ingenious wedge-shaped design makes the valve have an automatic sealing function as the valve is […]

Comparison and analysis of the performance of the wafer butterfly valve

With the same nominal pressure and nominal diameter, ordinary which has better tightness and is not easy to leak? butterfly valve or gate valve? The airtightness of the gate valve is better than that of the butterfly valve, but there are also manufacturers’ butterfly valves that have better airtightness. The gate valve is large in […]
