Control Ball Valve

• Integrally cast ANSI 150 or 300 class raised face flanges. Eliminates long tie rods and simplifies alignment.
• Installation flexibility – Two face-to-face dimensions are available. Standard construction is in accordance with ISAS75.04 and IEC 534-3-2. Also available in ANSI B16.10short pattern face-to-face dimensions – ANSI class 150 only.
• Straight through flow pattern provides exceptional capacities.
• Patented dual-characterized V-port ball combines an equal percentage flow characteristic with high capacities and greater than 500:1 range ability.
• Standard EF Seal (Emission Free) packing system provides long term, zero leakage† shaft sealing performance.
• MN-7 low-friction polymeric seal ring provides reliable Class VI shutoff.
• 316 Stainless Steel seal ring for Class IV shutoff and higher temperature capability when combined with satellite bearings and flexible graphite packing. Unique seal design requires no shims.
• Heavy Duty Seat provides longer service life in harsher applications. The wiping action of the seal ring against the ball prevents build up of contaminants maintaining long-term performance and reliable Class IV shutoff.
• Full in volute spline connections on plug, shaft and actuator connections virtually eliminate backlash, providing reliable operation and ease of maintenance.
• Easy maintenance – The seal ring may be changed by simply removing two machine screws on the inlet flange. Actuator removal or complete valve disassembly is not required.
