SERIES 815 ANSI CLASS 150 AND SERIES 830 ANSI CLASS 300 WAFER-SPHERE® HIGH PERFORMANCE BUTTERFLY VALVES

JAMESBURY®'s WAFER-SPHERE high-performance butterfly valves provide long-lasting tight shutoff capability, excellent flow characteristics, and long service life. The following standard sizes are available:		CE Marked Versions Available ■ CE marked and documented valves that conform to the European Pressure Equipment Directive (PED) 97/23/EC are available in ANSI Class 150/300, both standard and FIRE-TITE® construction. Operating torques, construction options and valve dimensions are exactly the same as the standard ANSI 150/300 offering. The applicable sizes for CE marked values are shown in table to left. Positive Shaft Retention ■ 2-1/2"- 24" (DN 65 - 600) valves are equipped with a retaining ring at the top of the shaft to prevent movement of the top portion of the shaft past the compression ring if for any reason the shaft should break within the valve . Easy Seat Maintenance ■ Simply remove body insert and replace seat - disassembly of disc and shaft is not required Excellent for both On-Off and Control Applications ■ Superior control characteristics ■ Inherent flow characteristic is modified equal percentage ■ Wide rangeability ■ Tight shut-off even in control applications ■ Standard lugged style valves are suitable for bidirectional dead-end service at the full pressure-temperature rating of the valve. Single-Source Responsibility ■ Purchase valves, actuators, and accessories, completely mounted from one source ■ Available with electric, manual gear, and pneumatic double acting or spring return actuators and a variety of accessories including limit switches, solenoids, and positioners ■ OEM service available through world-wide service centers Available in a Wide Choice of Materials for a Broad Range of Applications ^ Standard body materials include ductile iron, carbon steel,stainless steel,Alloy 20,and Monel®.Other materials, such as Avesta® 254SMO are available on application.	1 o ⁶m z ² o o to
