Manual U-shaped butterfly valve

The U-shaped flange butterfly valve uses a three-dimensional eccentric principle design, making the spatial movement trajectory of the sealing surface ideal. The sealing surfaces are frictionless and interference-free, and with the proper selection of sealing materials, the butterfly valve's sealing performance, corrosion resistance, high-temperature resistance, and wear resistance are reliably ensured.
Using a top-mounted structure reduces the number of connecting bolts on the valve body under high-pressure and large-diameter conditions, enhancing the valve's reliability and overcoming the influence of the system's self-weight on the valve's normal operation. The structure is simple, with good universality and interchangeability, convenient maintenance and disassembly, and the stem seal is not easily deformed, avoiding stem leakage. The valve seat sealing surface and backing are integrated, reducing the deformation of the valve seat. Its features include small opening torque, flexibility, convenience, and energy saving. The three-dimensional eccentric structure makes the butterfly plate tighter as it closes, ensuring reliable sealing performance and achieving zero leakage. It is resistant to high pressure, corrosion, and wear, and has a long service life.

Soft-Seated wafer Butterfly Valve

The butterfly plate of a wafer-type butterfly valve is installed in the diameter direction of the pipe. Within the cylindrical passage of the valve body, the disc-shaped butterfly plate rotates around its axis, with a rotation angle between 0° and 90°, achieving flow regulation. When the plate rotates to 90°, the valve reaches its maximum opening.
Wafer-type butterfly valves have a simple structure, small size, and light weight, consisting of only a few parts. Furthermore, they can be quickly opened and closed with a 90° rotation, making operation simple. At the same time, this valve has good fluid control characteristics; the structural principle of the butterfly valve is particularly suitable for manufacturing large-diameter valves.
Wafer-type butterfly valves are widely used in coal chemical, petrochemical, rubber, papermaking, and pharmaceutical pipelines as flow-splitting, flow-merging, or flow-switching devices; the valve body uses precision casting for a smooth surface without burrs or pinholes.

Headless butterfly valve

The butterfly plate of a wafer butterfly valve is installed in the diameter direction of the pipe. Inside the cylindrical channel of the valve body, the disc-shaped butterfly plate rotates around the axis, with a rotation angle between 0°-90°, which can regulate the flow rate. When the plate rotates to 90°, the valve reaches its maximum opening. Wafer butterfly valves have a simple structure, small size, and light weight, consisting of only a few parts. They can be quickly opened and closed with a 90° rotation, making them easy to operate.

Electric single flange powder butterfly valve

Powder butterfly valves feature a simple structure, wear-resistant butterfly plates, long sealing life, and easy installation. The valve body is made of lightweight, high-pressure cast aluminum alloy, making it lightweight. The valve plate is lined with a wear-resistant polymer material with a steel core, forming a highly wear-resistant soft seal with a wear-resistant rubber sealing ring. It can be used even under extremely high wear conditions. It can be installed on hoppers, silos, screw conveyor outlets, and pneumatic conveying pipelines. The flange surface can be selected as a single flange or a double flange as needed. Double flange butterfly valves have two identical flange surfaces, while single flange valves have an extended connecting ring at the bottom for installing a sleeve.

Manutal full-lined PTFE butterfly valve

A full-fluorine lined butterfly valve is a valve that uses a disc-type shut-off member to reciprocate and rotate approximately 90 degrees to open, close, and regulate the fluid passage. Full-fluorine lined butterfly valves not only have a simple structure, small size, light weight, and low material consumption, small installation dimensions, but also require a small driving torque, are easy and quick to operate. Installed in high-altitude dark passages, it is convenient to operate via a two-position five-way solenoid valve, and it can also adjust the flow rate of the medium. The fluid resistance is relatively small. For large-diameter pneumatic butterfly valves, the effective flow area is large when fully open, opening and closing is quick and effortless, and the disc rotates 90 degrees to complete opening and closing. Full-fluorine lined butterfly valves further improve the performance of butterfly valves, resulting in valves with wider temperature and pressure ranges, better sealing performance, and longer service life. They can also simultaneously have good flow adjustment function and closing sealing characteristics.
