重要な技術的利点
-
Powerful Thrust Output: Capable of producing maximum thrusts of up to 76.3 kN (17,155 lbf), the 3025 delivers the force necessary to maintain tight shutoff and precise positioning against high process differential pressures.
-
Long Stroke Capability: Unlike standard diaphragm actuators that are often travel-limited, the 3025 supports strokes up to 200 mm (8 inches). This makes it an ideal match for large-bore globe valves and applications requiring extensive valve plug travel.
-
On-Site Reversible Fail Mode: One of the most flexible features of the 3025 is the ability to change the fail mode (direct or reverse-acting) directly on-site. This conversion can be accomplished without the need for additional parts, significantly simplifying inventory management and field adjustments.
-
Integrated Bias Springs: The actuator includes robust bias springs that ensure a positive mechanical fail-safe position upon loss of supply air. This mechanical return provides an essential layer of safety for critical process loops.
-
Manual Override Support: For manual intervention during startup, maintenance, or air-loss events, the 3025 can be equipped with a side-mounted handwheel. This allows for manual positioning without disconnecting the pneumatic supply.
-
Rugged Environmental Protection: Built for the rigors of the field, the 3025 features a heavy-duty casing and yoke assembly. This rugged construction provides the stability needed to resist vibration and a high degree of corrosion protection for long-term outdoor service.
