Manual butterfly valve is a kind of butterfly valve, usually soft seal, which consists of rubber or fluorine plastic sealing material sealing surface and carbon steel or stainless steel valve disc, valve stem. Because the sealing surface material is limited, the butterfly valve is only suitable for water, gas, oil and other fluid media with a temperature of 80 ~ 120℃. The application fields are chemical, petroleum, electric power, textile, paper making, building water supply and drainage and other engineering systems to transport a variety of corrosive and non-corrosive fluid media pipelines, which are used for switching control of normal temperature and atmospheric pressure pipeline media. Can also be used to adjust the flow.

The design structure of the price butterfly valve is simple and unique, small volume, light weight and easy to operate. Small caliber operation torque is small, labor-saving dexterity, quick opening and closing. It can be installed anywhere in the pipeline for easy installation and maintenance. The grip butterfly valve is usually soft seal, reliable sealing performance, can achieve bi-directional sealing zero leakage. The sealing surface material is easy to replace, resistant to aging and weak corrosion, and has a long service life.

The valve disc of the handle butterfly valve is made of ductile iron material, and its tensile strength and yield strength are higher than that of ordinary cast iron, which makes the handle of ductile iron material have better mechanical properties on the 6 inch butterfly valve and can withstand greater pressure and impact. With the sealing ring, good sealing effect can be achieved and the possibility of leakage can be reduced while ensuring the valve performance. Improve valve durability and reliability, resulting in a higher cost/performance ratio.
