Introduction
The bulletin provides comprehensive details on the MAXUM™ RCV Rotary Control Valve, including specifications, materials, and ordering procedures. It covers construction types, applicable standards, and materials used in manufacturing these valves by SPX Process Equipment.

Flanged and Flangeless Construction
Valves are available in flanged and flangeless designs, suitable for Class 150 and 300 applications, with sizes from 1" to 12" (25mm to 300mm).

Valve Selection and Specifications
A table outlines maximum shutoff pressure differentials and flow characteristics for various valve sizes. Cv/Kv values are provided for valves fully open, along with applicable ANSI and IEC standards for dimensions and pressure ratings.

Materials of Construction
The document details materials for valve components, including 316 and 317 Stainless Steel, Hastelloy C, Carbon Steel, and Titanium, with specific ASTM grades and overlays for parts like the body, ball, retainer, and bearings.

Ordering Information
Instructions include specifying valve style, size, end connection, body material, packing material, trim combination, and options, with an example order code provided.

Dimensions
Dimensions for various valve sizes are provided, including face-to-face measurements according to different standards (ANSI, ISO, EN, ISA, IEC).

Actuators
Manual gear actuators are made from cast iron with sintered bronze bearings. Cylinder actuators are also available, with references to additional bulletins for technical and sizing details.

PowerRac® Cylinder Actuators
These actuators are available in double-acting or spring return configurations, providing high torque for on-off and modulating services. Refer to Bulletins 74.00-2, 74.00-1, and 74.00-4 for more details.

Spring-Diaphragm Actuators
Constructed from steel, cast iron, and stainless steel, these actuators avoid aluminum to prevent corrosion. They offer on-off or modulating control with spring-to-open or spring-to-close operations, featuring external position indication and optional safety lockout devices. Refer to Bulletins 70.00-1 and 70.00-2 for more information.

MAXUM™ RCV Rotary Control Valve
Detailed dimensions and specifications are provided for valve sizes from 1" to 12" (25mm to 300mm), including seat side and tie bolt lengths for flangeless valves and bolt lengths for flanged valves.
