Ball valve:
Materials:
Body: steel, ball: 1.4408, seals: PTFE / FKM (PN 16: Housing: GG25, ball: hard chrome-plated brass, seals: PTFE/NBR)
Temperature range:
-20 °C to +180 °C (PN 16: -10°C to +100°C)
Media:
Water, oil, compressed air, fuels (DN 15 to DN 32: also vacuum down to -0.9 bar)
Rotary actuator:
Description:
Electrical rotary actuator with optical position indicator, manual emergency operation and switch room heating Two additional limit switches are installed for further control requirements. An electronic torque limiting unit prevents damage in the event of overload. The manual emergency operation can be done without dismantling the external cladding. Do not use upside down!
