Product catalog summary

Materials of Construction
The BRS Resilient Seated Butterfly Valves are available in sizes from 2 to 36 inches. Materials used include cast iron, ductile iron, bronze, and stainless steel, selected based on valve size and application requirements to ensure durability and compliance with ASTM and AWWA standards.

Valve Selection
Designed for zero-leakage shutoff at specified pressure ratings, these valves support a maximum pipeline velocity of 20 feet per second. Detailed weight specifications are provided for wafer and lugged valve designs across different sizes.

Flow Characteristics
The valves meet several ANSI and AWWA standards, ensuring reliable performance. The document details inherent flow characteristics, providing Cv and Kv values for various valve sizes and opening percentages.

Ordering Information
Customers must specify valve style, size, end connection, seat material, body material, shaft material, and additional options like flange seals. A comprehensive guide is provided for constructing the order code based on these parameters.

Actuators
Various actuator options are described, including lever actuators with ten-position and infinite-position levers, manual gear actuators, and PowerRac® cylinder actuators. Each type offers precise control and durability, with specific ordering codes and mounting options.

Overview
The document provides technical specifications and dimensions for various actuators and resilient seated butterfly valves, including diaphragm actuators, Compak cylinder actuators, and BRS resilient seated butterfly valves.

Diaphragm Actuators
These actuators offer on-off or modulating control with spring-to-open or spring-to-close options, featuring external position indication and optional safety lockout devices. Refer to Bulletin 70.00-1 for technical details and Bulletin 70.00-2 for sizing information.

Compak Cylinder Actuators
Designed with a versatile rack-and-pinion mechanism, these actuators are available as double-acting or spring-return units. Their compact, modular design allows for low-profile assembly, matched to each valve's torque requirements for economical specification. Ordering information is in DeZURIK Bulletin 71.00-1.

BRS Resilient Seated Butterfly Valves
Detailed dimensions are provided for butterfly valves ranging from 2" to 36" (50mm to 900mm), including measurements for various components. Note that dimensions are subject to change, and certified drawings should be requested for precise piping layouts.

Additional Information
SPX Process Equipment is ISO 9001 certified. The company reserves the right to make design and material changes without notice. For further information, certified drawings, and local representatives, visit the SPX Process Equipment website or contact their sales and service department.
