LN200 Series | 6-Bolt Pattern Wafer Butterfly Valve
C&C Industries
The C&C LN200 Series 6-Bolt Pattern Wafer Butterfly Valve is engineered for applications requiring enhanced mounting stability and secure alignment in high-cycle or vibration-prone systems. Its 6-bolt pattern design provides improved structural support compared to standard wafer configurations, reducing movement and maintaining consistent sealing performance.
Built with a ductile iron body and a range of disc and seat material options, this valve delivers flexibility across varying media and operating conditions. The square shaft design supports reliable torque transfer, making it well-suited for automated and manual actuation.
Designed for durability and precision, the LN200 6-Bolt Pattern is a dependable solution for applications where mounting integrity and consistent operation are critical.

PERFORMANCE ADVANTAGES
Why the LN200 Series Wafer BFV Performs Where It Counts
RIGID PIPELINE ENGAGEMENT
WITH 6-BOLT PATTERN
The 6-bolt pattern increases clamping force distribution across the flange connection, reducing the likelihood of valve shift, rotation, or misalignment under pressure fluctuations or vibration. This is especially critical in skid-mounted systems, compressor stations, and high-cycle applications where standard wafer bodies can experience movement over time.
CONSISTENT ACTUATION THROUGH
SQUARE SHAFT DESIGN
The square shaft provides positive engagement between the valve stem and actuator, eliminating play that can occur in double D configurations under repeated cycling. This results in more accurate valve positioning, reduced backlash, and improved control in automated systems.
CONTROLLED SEAL PERFORMANCE ACROSS MULTIPLE MEDIA TYPES
With seat options including Buna-N, EPDM, FKM, PTFE, and natural rubber, the valve can be matched to specific chemical compatibility and temperature ranges. This prevents premature seat degradation, swelling, or hardening that typically leads to leakage or torque increase.
STRUCTURAL STABILITY
IN HIGH-CYCLE APPLICATIONS
The combination of ductile iron construction and reinforced mounting pattern allows the valve to maintain dimensional stability through repeated open and close cycles. This minimizes deformation at the seat and disc interface over time.
