Elastic seat butterfly valve is a type of valve that relies on an elastic seal ring to achieve good closing performance. It is widely used in water treatment, HVAC, chemical, food and beverage industry pipeline systems for cutting off or regulating medium flow.
Elastic seat butterfly valve adopts rubber or polytetrafluorethylene as the seat material, with good sealing and corrosion resistance, and can provide manual, electric, pneumatic and other driving methods. Its design features include:
Secondary SEAL DESIGN: THE primary seal is obtained by prepressing the polished shoulder of the valve plate and the inner surface of the valve seat. The secondary seal is the interference fit between the valve seat shaft hole and the valve stem, effectively preventing the media from leaking from the valve stem to the outside of the valve body.
Temperature range: According to different seat materials, the applicable temperature range is different, such as EPDM EPDM rubber seat valve applicable temperature is -40℃ to 120℃, NBR nitrile rubber seat valve applicable temperature is -15℃ to 100℃, PTFE/EPDM polytetrafluorethylene (PTFE/EPDM) gasped EPDM rubber seat valves are suitable for temperatures from -40 ° C to 150 ° C and instant temperature up to 180 ° C.
Replaceable seat design: reduces maintenance costs.
Self ADJUSTABLE DOUBLE V stem PACKING: Self - compensated and two - way seal ensures that no external material can enter the body through the stem.
Seat MOLDED one-PIECE O-RING: No additional gasket is required to maintain flange seal during installation
