Advantage

Warranty: 2 years
Overload Protection: The power will automatically shut off when the valve jam occurs. Thus preventing further damage to the valve and actuator
Operational Safety: F 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 Protection: Protection against the high and low voltage situations.
Applicable valve: Ball Valve (DN15-DN200); Butterfly Valve (DN25-DN400)
Anti-corrosion Protection: Epoxy resin enclosure meets NEMA 4X, customer-special painting is available
Ingress Protection: IP67 is standard, Optional: IP68( Maximum 7m; Max: 72 hours)
Fireproofing Grade: High temperature fireproof enclosure meets requirements in different situation
