ROOAR-667 NS 032994 - Ingersoll-Rand Parts

The ROOAR-667 NS 032994, available through Ingersoll-Rand Parts, is a robust and reliable reverse-acting, spring-opposed diaphragm actuator engineered for precision control in various industrial and automotive processes. This professional-grade actuator is designed to provide dependable on-off or accurate throttling operation for automatic control valves, responding to varying pneumatic loading pressures. It ensures critical system regulation with consistent performance.

Key Features

• Reverse-Acting Design: Applies upward force on the valve stem with increasing pneumatic pressure, providing flexible control configurations for sliding-stem valves.
• Durable Construction: Built with thick-walled cast iron and steel components, offering excellent stability, extended service life, and enhanced corrosion protection in demanding environments.
• High Thrust Capability: Features a molded diaphragm that maintains consistent effective area throughout its travel, maximizing thrust for a given diaphragm size.
• Optimized Responsiveness: Engineered with a shallow casing on the pressure side to minimize internal volume, leading to a high degree of dynamic stability and rapid frequency response.
• Seismic Rated: Its yoke construction and specialized bonnet-to-yoke bolting contribute to a high structural resonant frequency, exceeding most nuclear service seismic requirements.
• Fail-Safe Operation: Configured to provide fail-closed action for "push down to close" valves if the pneumatic signal pressure is lost, enhancing operational safety.

Applications

The ROOAR-667 NS 032994 diaphragm actuator is ideal for professional technicians and mechanics requiring precise control in process automation. Common applications include:

• Process Control Systems: Essential for maintaining critical parameters in manufacturing, chemical processing, and power generation.
• Industrial Automation: Used in various industrial settings where automated valve operation, either on/off or throttling, is required for fluid and gas management.
• HVAC Systems: Employed in large-scale climate control to regulate air and water flow.
• Water and Wastewater Treatment: Provides reliable control over flow rates and chemical dosing.
