Products Details

Soft seal manual clamp butterfly valve is a kind of valve widely used in oilfield, agriculture, water and wastewater treatment and mining fields. The following is a detailed introduction to its characteristics and applications:

Structural features:

Small and lightweight: The valve is compact, easy to install and maintain, and can be installed in any position.
Easy to operate: the opening and closing of the valve is achieved by 90° rotation, with small operating torque, labor-saving and lightweight.
Good sealing performance: rubber seat ring, can achieve zero leakage, suitable for low pressure pipeline.
Two-way seal: The valve has a two-way seal function, which is not limited by the flow direction of the medium when installed.
Materials and Design:

Body material: Common materials include cast iron, cast steel, stainless steel, etc. The specific material selection depends on the application environment and the type of media.
Sealing materials: Commonly used sealing materials are NBR (nitrile butadiene rubber), EPDM (EPDM), PTFE (polytetrafluoroethylene) and VITON (fluorine rubber), these materials have different temperature resistance and chemical corrosion resistance characteristics.
Scope of application:

Industrial application: Suitable for petroleum, chemical industry, urban gas, urban heating, water treatment and other fields, used to regulate the flow of media and cut off the flow of media.
Food and pharmaceutical industry: due to its good sealing performance and corrosion resistance, it is also commonly used in food, pharmaceutical, power, textile, paper and other industries of drainage, gas pipeline system.
Operation and maintenance:

Manual operation: The valve is manually operated by handle or lever, easy to operate and easy to control flow.
Easy maintenance: Due to the simple structure of the valve, the maintenance cost is low, and the seal can be replaced to ensure long-term reliable sealing performance.
Dimensions and Specifications:

Size range: Common sizes range from DN40 to DN1200, the specific size and pressure level can be selected according to the application needs.
Pressure levels: Common pressure levels include PN10 to PN16, which are suitable for different working pressure requirements.
Standards and Certifications:

Design and manufacturing: comply with API 609, EN 593, AWWA C504 and other international standards.
Test and inspection: comply with API 598, EN 12266 and other test and inspection standards.
Through the above introduction, it can be seen that the soft seal manual clamp butterfly valve has a wide range of application prospects in a variety of industrial applications because of its simple structure, easy operation and good sealing performance.
