Product description
The handle fire-fighting groove butterfly valve has the advantages of fast installation, simple, safe and reliable installation, not restricted by the installation site, convenient for the maintenance of the pipeline and the valve, vibration isolation and sound insulation, and overcomes the imitation difference caused by the pipeline connection with different axes within a certain angle range , Solve the advantages of thermal expansion and contraction caused by temperature difference. It is widely used in the water supply and drainage of the conveying fluid pipeline, as the control fluid in the pipeline engineering of fire fighting, air conditioning, gas, petroleum, chemical industry, water treatment, municipal administration, and shipbuilding.
Features
1. The valve adopts a centerline sealing structure design, with light torque and good sealing performance;
2. The butterfly plate and valve stem are connected by a pinless design, with good connection reliability;
3. The butterfly plate adopts rubber vulcanization as a whole, with good corrosion resistance;
4. The connection between the valve and the pipeline adopts the clamp connection form, which is convenient and fast to install;
5. The valve has diversified drive modes, which can be equipped with handle operation, worm gear operation, electric and pneumatic operation modes.
