Technical features

Manufacturer warranty2 years
Overload ProtectionThe power will automatically shut off when the valve jam occurs. Thus preventing further damage to the valve and actuator
Operational SafetyF grade insulation motor. The motor winding has a temperature control switch to sense the temperature of the motor to protect the overheating issues, thus ensures the operational safety of the motor.
Voltage ProtectionProtection against the high and low voltage situations.
Applicable valveBall Valve; Butterfly Valve
Anti-corrosion ProtectionEpoxy resin enclosure meets NEMA 4X, customer-special painting is available
Ingress ProtectionIP65
Fireproofing GradeHigh temperature fireproof enclosure meets requirements in different situation
