soft seal flanged butterfly valve Description
A soft-seal flanged butterfly valve is a type of valve where the closing element (butterfly plate) is a disc that rotates around the valve stem to open and close. It primarily functions as a shut-off and throttling valve in pipelines. The butterfly plate is driven by the valve stem; a 90° rotation completes one opening and closing cycle. Changing the deflection angle of the butterfly plate controls the flow rate of the medium.
Common butterfly valves include wafer-type butterfly valves, lug-type butterfly valves, and flanged butterfly valves. Butterfly valves are suitable for use in pipelines transporting various corrosive and non-corrosive fluid media in engineering systems such as generators, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting, power generation, environmental protection, and building water supply and drainage systems. They are used to regulate and cut off the flow of the medium.

Soft Seal Flange Butterfly Valve main dimensions and weight (PN1.0 / 1.6MPa)


Features
1. Novel and reasonable design, unique structure, lightweight, and rapid opening and closing.
2. Low operating torque, convenient and labor-saving operation.
3. Can be installed in any position and is easy to maintain.
4. Replaceable seals, reliable sealing performance achieving bidirectional zero leakage.
5. Sealing materials are resistant to aging and corrosion, and have a long service life.
Advantages
Fast Response: The characteristics of the pneumatic actuator determine the rapid opening and closing of the valve, enabling quick response and adjustment in fluid control.
Good Sealing Performance: Utilizing flexible sealing elements, it effectively prevents leakage, providing reliable sealing performance, suitable for demanding control systems.
High Flow Capacity: The structural features of the butterfly valve allow for a large flow capacity, meeting the control needs of large-flow fluids.
Small Size and Light Weight: Compared to other types of valves, the pneumatic flange soft-seal butterfly valve is small in size and light in weight, facilitating installation and maintenance.
Applications:
Water Supply and Drainage Systems
Urban water supply and wastewater treatment plant inlet and outlet regulation; IP68 rated products can withstand the risk of valve well flooding.
Petrochemical Industry
Flow regulation and emergency shut-off of crude oil and natural gas pipelines; triple eccentric structure withstands high temperature and pressure, replacing traditional gate valves.
Food and Pharmaceutical Industry
Using 316L stainless steel valve bodies and food-grade sealing materials (such as silicone rubber), meeting hygiene standards, suitable for beer and beverage production lines.
Power Industry
Remote start-up and shutdown control of boiler feedwater and circulating water systems; electric actuators support 4-20mA analog signal adjustment.
Low Temperature Environments
Heating systems in extremely cold regions; optional wide temperature range actuators from -60℃ to +80℃.
Precautions:
Regularly check the wear of the sealing elements and replace damaged sealing elements promptly to ensure the valve's sealing performance.
Pay attention to the valve's operating pressure and temperature range, avoiding exceeding the valve's rated parameters.
For special media, select suitable sealing materials to ensure valve reliability and service life.
Regularly maintain and service the valves, check the working status and sealing performance of the pneumatic actuators, and ensure the valves operate normally.
