35002 Series Rotary Control Valve
Design & Manufactured with Masoneilan Technique
Forward:
• Flangeless body rating is a rugged ANSI Class 600.
• The triple, over-sized bearing system provides exceptional
plug shaft guiding.
• Heavy duty guide lugs assure quick, positive alignment during
installation.
• Flanged version available 1" through 12" (25mm through
300mm) in 150 or 300 ANSI and 1" through 8" (25mm through
200mm) in 600 ANSI.
• Shouldered shaft design.
• Powerful, low profile spring diaphragm actuator guarantees
positive “fail-safe” action.
• Splined shaft and actuator linkages, combined with low friction
techniques, assure minimum deadband and hysteresis.
• Straight through flow pattern provides high flow capacities.
• Standard integral extension bonnet allows for a wide range of
fluid temperature applications (-320°F to 750°F), (-195°C to
400°C).
• Large, highly visible valve position indicator.
• The unique self-aligning eccentric rotating plug provides tight
shut off and low dynamic forces.
• Combination handwheel/adjustable limit stop with locking
mechanism standard.
• A large variety of reduced trim options are available in all sizes.
• Slurry package available in all sizes.
• Totally enclosed actuator linkage.
• Complete line of options and accessories.

Notes:
1. The Model 70 double acting cylinder actuator must be assembled position 2-4-6 or 8 only, to close valve on actuator stem
retraction. The air action can be either air-to-open or air-to-close.
2. It is recommended that the actuator always be mounted as shown above. For other positions, consult local sales office.
3. Installation is assumed to be in horizontal pipeline for orientation of airset and other accessories unless specified on order.
4. Action and orientation field reversible without additional parts.
5. Operating efficiencies may vary depending on valve configuration.
6. The above schematic does not reflect every possible body/actuator orientation, but should serve as an effective guide.
