Overview of D671X pneumatic with manual butterfly valve
Pneumatic butterfly valve with manual butterfly valve is the preferred centerline soft sealing butterfly valve for pipelines. It has simple structure, small flow resistance coefficient, flow characteristics tend to be straight, and no debris will be retained. And it has the advantages of light weight, convenient installation and small driving torque. Pneumatic butterfly valve can be used to cut off the medium, and can also be used to adjust the flow of the medium. The driving device can be manual, electric, pneumatic, etc. according to user requirements. The parts of different materials are selected, and the sealing rings of different materials are used, which can adapt to different media and working conditions, so that the cost and performance can reach the best effect.
Pneumatic butterfly valve with manual is suitable for water supply and drainage, sewage, food, heating, gas, ship, hydropower, metallurgy, energy system, textile and other industries with temperature ≤120℃ or ≤150℃ and nominal pressure ≤1.6MPa, especially suitable for two-way sealing And the valve body is easy to rust occasions, as the flow adjustment and interception medium.
D671X pneumatic with manual butterfly valve features:
1. Small and light, easy to disassemble and repair, and can be installed in any position.
2. The structure is simple and compact, the operating torque is small, and the 90° turn to open quickly.
3. The flow characteristics tend to be straight, and the regulation performance is good.
4. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.
5. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the valve. It still maintains zero leakage for more than 50,000 times of opening and closing under pressure.
6. The seals can be replaced, and the sealing is reliable to achieve two-way sealing.
7. The butterfly plate can be sprayed with a coating layer, such as nylon or PTFE, according to user requirements.
8. The valve can be designed as flange connection and wafer connection.
9. The driving mode can be manual, electric or pneumatic.
Main structural form:
1. Cylinder form: single-cylinder or double-cylinder;
2. Cylinder working pressure: 0.4~0.7Mpa;
3. Cylinder switching time: double-acting 1~5 seconds;
4. Cylinder empty consumption: 1~131L;
5. Solenoid valve power supply: 220V AC, 24V DC.
6. A hand wheel can be attached. When the cylinder cannot work, it can be closed and opened by the hand wheel.
