Series | Code | Description |
L1 | SLANSI300 | SERIES L1 HIGH PERFORMANCE TRIPLE ECCENTRIC METAL SEATED BUTTERFLY VALVE, PRESSURE CLASSES ASME300 & PN25-40, FLOW BALANCING TRIM S-DISC |
Neles™ S-disc™ is a flow balancing trim for Neldisc™ butterfly valves. A dynamically balanced Neldisc™ triple eccentric disc valve has up to 8 dB(A) noise reduction compared to the standard valve. This valve can push butterfly valve application envelope higher. The dynamic forces affecting the disc when throttling are transferred to the valve body, balancing dynamic torque and reducing bearing load. Valve itself is the standard Neldisc™, the only changed part is the clamp ring. Wafer (L1) and lug (L2) type bodies to fit ANSI 150 or DIN 10, 16 and 25 pipe flanges.
