Robust Construction and ProtectionCrafted from powder-coated die-cast aluminum with a double-sealed housing, the QT Series actuator achieves IP67 protection, making it ideal for harsh industrial settings. Its design shields the internal mechanism against dust, water ingress, and corrosion, ensuring long-term reliability even in challenging environments.
Versatile Control and OperationSupporting On/Off, modulating, and manual override control modes, the actuator adapts to a broad range of automation requirements. Fast actuating times (8-30 seconds) and visual position indication provide precise, responsive control, while torque protection and a 70% continuous duty cycle deliver consistent operation in demanding tasks.
FAQ's of Quarter Turn Electric Actuator:
Q: How is the QT Series Quarter Turn Electric Actuator installed on valves?
A: The QT Series actuator is designed for direct mounting in compliance with ISO 5211 standards. Suitable for ball and butterfly valves (DN15 to DN200), it can be connected via flanged or threaded pipe connections, making it compatible with various valve types and sizes.
Q: What applications benefit most from using this electric actuator?
A: This actuator is ideal for automated valve operations in industries handling water, air, oil, or gas. Its durability, overload protection, and wide operating temperature range make it suitable for utility plants, process industries, and fluid control systems requiring reliable and precise actuation.
Q: When should the manual override feature be used?
A: The manual override should be utilized during power loss, system maintenance, or any situation requiring hand control over valve position. This ensures continuous process control and system safety even if electrical supply or control signal is interrupted.
Q: Where can the QT Series actuator operate effectively?
A: The actuator is suitable for both indoor and outdoor use, thanks to its IP67-rated, double-sealed housing. It operates reliably in environments with ambient humidity up to 90% RH and temperatures ranging from -25C to +70C, making it resilient to most industrial conditions in India.
Q: What process parameters can be controlled using this actuator?
A: The actuator supports both On/Off and modulating control, allowing regulation of fluid flow through ball or butterfly valves. Its rapid actuation (8-30s) and torque range (50Nm-2000Nm) facilitate precise management of flow rates, especially in variable flow applications.
Q: How does the actuator enhance operational safety and performance?
A: Incorporating overload protection with automatic cutoff and a sturdy insulation class F rating, the QT Series prevents motor overheating and overload-related failures. The visual position indicator enhances operational awareness, supporting safe and efficient control for automated systems.
