Product Advantage
High performance (Double-Offset /Eccentric) Design: The shaft is offset from the disc centerline and pipe centerline, reducing seat wear and friction during operation. This ensures a tight seal, minimizes leakage, and enhances longevity.
Sealing: Equipped with resilient seats, typically RPTFE (reinforced Teflon) for enhanced temperature resistance (up to ~200°C) or EPDM/NBR for general applications. Some models offer replaceable seats for easy maintenance.
Bi-Directional Sealing: Provides reliable sealing under full pressure in both flow directions, ideal for preventing backflow.
High Flow Capacity: The streamlined disc design ensures large flow capacity with low pressure drop, optimizing fluid control.
Actuator Support: Worm gear, pneumatic or electric actuators are commonly supported, ensuring precise control. Electric models maintain position on power loss, while spring-return pneumatic models fail closed.
