In demanding industrial environments where performance, safety, and flexibility are essential, having a reliable valve actuator system can make all the difference. Valworx’s Pneumatic/Manual Combination actuators offer a powerful and efficient solution for operating quarter-turn valves and dampers—delivering advanced control with the convenience of manual override functionality.
Multi-Function Control in a Single Actuator
Valworx’s air and manual combination actuator products are engineered for versatility. Designed to operate pneumatically, manually, or with stroke limitation, these actuators are ideal for managing ball valves, butterfly valves, plug valves, and dampers. Their integrated manual override ensures uninterrupted operation, even in the event of pneumatic failure, making them a dependable choice for critical systems.
Double-acting models use air pilot pressure to both open and close the valve, ensuring rapid, consistent actuation. In contrast, spring-return models use air pressure to open and rely on a failsafe spring mechanism to close the valve—essential in applications where safety and default-to-close functionality are required.
Stroke Limiting for Precision Control
What sets the Valworx pneumatic/manual combo actuator apart is the integrated stroke-limit feature. This allows users to precisely define the open and close limits using a built-in handwheel—enabling more accurate flow control and helping prevent valve damage from over-travel. Whether limiting full closure or partial opening, this feature offers fine-tuned performance without the need for external components.
Designed for Demanding Applications
Built with robust engineering and high-performance materials, Valworx actuators are suitable for a wide range of challenging environments. Key benefits include:
- Integral Manual Override: Maintain full valve control during power or pressure loss
