High pressure ball valves with electric rotary actuators (industrial version), up to PN 500

Ball valve:
Materials: housing: Zinc plated steel, cone: Hard chrome-plated brass (DN 32 to 50: Hard chrome-plated steel), ball seal: POM, selector shaft seal: NBR
Temperature range: -10°C to max. +80°C
Operating range: Hydraulic oil, heating oil (water only after release by us)
Optional: Ball valve made of stainless steel 1.4571 -ES
Rotary actuator: 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.
Temperature range: -10°C to max. +70°C

Protection class: IP 65
Power-on time: 75 %
Regulating time: 8 to 12 seconds
Optional: Regulating time 140 sec. (only for actuator size 2) -140, "Battery Safety Return" for emergency closing NC (standard configuration) or emergency opening NO (switch via jumper) if there is a power failure -BSR
Warning: In case of high media temperatures, the actuator must be cooled if necessary!
**Installation length, stainless steel: 113 mm
*Dimensions and replacement actuators can be found further on in this chapter.
