The V-Max* rotary control valve offers high-capacity, heavy-duty
automatic throttling capability. The valve’s advanced design features
offer substantial benefits, including:
• Simplified alignment. The valve’s integrally cast raised face flanges
(in compliance with ASME 150 or 300 Class standards) eliminate the
need for long tie rods, significantly simplifying the alignment process.
• Installation flexibility. To meet a variety of application needs,
the valve is available with two different face-to-face dimensions:
standard construction complies with ISA S75.04 and IEC 534-3-2
standards and a short pattern complies with the ANSI B16.10
standard (ANSI class 150 only).
• Enhanced flow capacities. A straight-through flow pattern provides
exceptional capacities, while the patented dual-characterized
V-port ball combines an equal percentage flow characteristic with
high capacities and greater than 500:1 rangeability.
• Excellentleakagecontrol.AstandardEF(emissionfree)seal

• Flexible,reliableshutoffoptions.Threedifferentsealtypesprovide
flexible solutions for a variety of applications.
— MN-7 Seal Ring – This low-friction polymeric seal ring provides
reliable Class VI shutoff capability.
— 316 Stainless Steel Seal Ring – This unique seal ring design does
not require shims. It achieves Class IV shutoff and higher tem-
perature capability when combined with satellite bearings and
exiblegraphitepacking.
— Optional Heavy-duty Metal Seal Ring – This optional (NPS1-6)
heavy-duty seal ring provides long service life in harsh applica-
tions. The wiping action of the seal ring against the ball prevents
buildup of contaminants, helping maintain long-term perfor-
mance and reliable Class IV shutoff.
• Reliable operation, simplified maintenance.Fullinvolutespline
connections on plug, shaft, and actuator connections virtually
eliminatebacklash,enhancingoperationalreliabilityand
simplifying maintenance needs. Changing the ring seal requires
only the simple removal of two machine screws on the inlet flange.
