Match the seat to the service
Temperature capability depends on the selected EPDM, NBR, HEPDM or FKM seat and the process medium. State both normal and maximum temperature.

Roger@henovalve.comModel HF-520
A centerline wafer butterfly valve with an ADC12 die-cast aluminum alloy body and configurable disc, seat and actuation options for compatible services.
At a glance
HF-520 is a configurable product family. Size, pressure, disc, seat, operator and connection compatibility must be considered as a complete selection.
The product range begins at DN32.
Handle operation is available through DN150; other operator routes extend to DN300.
Working-pressure options include 0.6, 1.0 and 1.6 MPa.
