Key Features:

1. Double Offset Eccentricity

• Significantly reduces operating torque compared to concentric designs, enabling smaller actuators.

• Its cam action lifts the disc away from the seat immediately upon opening, substantially minimizing friction and wear on the sealing surfaces for longer seal life.

• This design provides excellent, bubble-tight shutoff (especially with resilient or metal seats) and suitability for higher pressures and temperatures. 

2. Pneumatic Actuation Excellence

• Enables rapid actuation and automation: Pneumatic actuators provide very fast opening and closing speeds, allowing for precise process control and easy integration into automated systems.

• Offers high torque with energy efficiency: They deliver high force output suitable for demanding valve sizes, while typically requiring less energy to operate compared to electric actuators for equivalent torque.

• Ensures reliability and safety: Pneumatic systems are robust, require minimal maintenance, and inherently support critical fail-safe modes (air-to-open or air-to-close) for safety in power loss situations.

3. Double Flanged Robustness

• Simplifies Installation and Sealing: The flanges on both ends provide robust, bolt-on connections to piping systems, ensuring reliable sealing with standard gaskets and minimizing leakage points.

• Offers High Structural Integrity: The full flanged body design provides greater strength and rigidity compared to wafer or lug styles, making it suitable for higher pressure applications and reducing pipe strain.
