Quarter-turn actuators are used to operate ball valve, plug valve or butterfly valve, damper valve, louver valve and any quarter-turn or part-turn device like: flue cut-off gate, boiler, primary and secondary wind, boiler's side wind, air preheater inlet and outlet damper regulator, etc.Protection Grade:lP67.
Features
Compact structure, large output torque
Self-locking gear train maintains valve position when actuator is de-energized
Very good vibration resistance
Very easy setup - no specific tools required Adjustable mechanical travel stop to prevent overtravel
Removable drive sleeve for easy machining
All actuators come standard with emergency handwheel and mechanical position indicator
Special Design
• Weatherproof design
As standard, our actuators are protected by IP67 (NEMA 4) weatherproof enclosures in accordance with CEI 144 recommendations. Higher levels of protection are available on request (please consult us).
• Corrosion resistant design
Our actuators can also be configured to operate in harsh environmental conditions such as: Industrial corrosive atmospheres (chemical, alumina plants, ie) Marine corrosive atmospheres (onshore and offshore)
