Series 530SB, 730SB, and 9300B Digester Blow Valves

Product catalog summary

Flow Data: The document provides flow coefficients for Type 730SB, 530SB, and 9300B valves. Cv values indicate the flow rate of +60˚F water through the valve at a 1 psi pressure drop, while Kv values are the metric equivalent for water at 16˚C with a 1 kg/cm² pressure drop. To convert Cv to Kv, multiply by 0.8569.

Valve Body Ratings: These ratings specify the maximum working pressure of the valve body, with seat ratings determining practical pressure limits based on service conditions. Hydrostatic test pressures are provided for valves with the ball half open.

Valve Types and Specifications: The document details the specifications for Type 530SB, 730SB, and 9300B digester blow valves, designed for pulp-mill applications. These valves are built to withstand extreme conditions, including pressure, temperature, corrosive and abrasive media, thermal shock, and flashing. Type 730SB and 530SB are standard-port configurations conforming to ASME/ANSI Class 300, while Type 9300B is a full-port design.

Valve Seat Ratings: A graph illustrates seat pressure and temperature limits, with shaded areas indicating working limits based on differential pressure with the valve ball fully closed. The dotted line shows maximum valve body pressure and temperature ratings for 316 and 317 stainless steel.

Torque Data: Torque tables guide actuator selection for digester blow valves at typical differential pressures. For higher pressures, contact the home office. The document includes torque output values and actuator selection tables for Jamesbury® actuators.

Bill of Material and Parts List: Detailed parts lists are provided for different valve types, specifying materials such as 316 and 317 stainless steel, PTFE, and various alloys.

Dimensions: The document includes detailed dimensions for each valve type, including approximate sizes and weights in both inches and millimeters.

Ordering Information: Instructions for ordering Type 530SB, 730SB, and 9300B digester blow valves are provided, including size, series, body style, special service, body materials, seat and seal code, body fasteners, valve type, end connection, and ball/stem material.
