Triple Offset Butterfly Valve Pneumatic Wafer Lug 300LB Carbon Steel 316 Trim
Triple Offset Butterfly Valve Pneumatic Wafer Lug 300LB Carbon Steel 316 Trim
Product Features
Solves the challenges of slow shutoff, leakage, and short service life in medium- and low-pressure valve applications! The WCB+316 gradient material strikes a balance between cost and performance, while the Class 300LB rating ensures safe and reliable performance under medium- and low-pressure conditions. The pneumatic actuator enables millisecond-level emergency shutoff, isolating the hazard source immediately; the soft seal provides excellent sealing performance, and the triple-offset design ensures smooth, friction-free opening and closing, significantly reducing the risk of safety incidents and overall operational and maintenance costs.
Product Advantages
● The non-penetrating long bolts with a closed-lug connection maintain consistent clamping force over time. With bolts on both sides applying force independently, the risk of external leakage is inherently lower.
● Under pressure from the disc, the sealing ring compensates for microscopic irregularities, easily achieving ANSI Class VI bubble-tight shutoff. It effectively seals water, oil, and gas—a feat that hard seals cannot match at the same cost.
● Based on the principle of three-dimensional eccentric geometry, the disc disengages from the seat the moment it opens and presses against it precisely the moment it closes. Throughout the 90° rotation, the sealing surfaces experience zero friction and zero scraping.
