Seal selection is central
The butterfly valve page lists multiple seal materials and temperature ranges. State the medium, working temperature and certificate needs before selecting NBR, EPDM, FKM, PTFE or metal sealing options.
Match the valve body and actuator together
The catalog combines shell material, disc material, DN size and actuator model in one ordering code. Pneumatic and electric actuator choices should be confirmed with valve size and torque conditions.
RFQ confirmation points
