Design Description
Zero-Friction Triple Offset Design: The eccentric geometry ensures the disc lifts off the seat immediately upon opening, eliminating seating friction, reducing operating torque, and extending seal life.
Fail-Safe Single Acting Actuation: Built-in spring return mechanism automatically drives the valve to a pre-defined safe position (fail-open or fail-closed) upon loss of pneumatic supply.
TISSIN Smart Positioner Precision: Advanced TISSIN digital positioner offers high-resolution position control, low air consumption, easy auto-calibration, and robust HART communication.
Bubble-Tight Metal Seating: Laminated stainless steel/graphite seal ring provides bidirectional bi-directional zero-leakage shut-off, complying with API 598 and ISO 5208 strict standards.
