Consolidated Type 3500 Electromatic* Ball Valve - 1

Consolidated* 3500 Series Electromatic* Ball Valve fact sheet Ensuring Safe Performance Overview The Consolidated Series 3500 Electromatic Ball Valve (EBV) from GE Oil & Gas is designed to provide automatic or manual over-pressure protection for your steam boiler system. It also can be used to assist startup and shutdown venting. Set to operate at a lower pressure than spring-loaded safety valves, the Consolidated Series 3500 EBV helps reduce safety valve maintenance and increases steam boiler efficiency. Key features and benefits of the 3500 EBV include: • Technologically advanced ball and seat coating for increased life expectancy • Superior stem design that provides structural integrity in extreme environments • Versatile design allows for omnidirectional assembly Specifications INLET SIZES 1.5” (38.1 mm), 2” (50.8 mm) and 2.5” (63.5 mm) in either flanged or weld neck design. INLET RATINGS ANSI Class 1500 thru 4500. OUTLET SIZES OUTLET RATINGS BORE SIZES .875” (22.23 mm) through 2.000” (50.8 mm). ­ educed bores are R available. TEMP. RANGE Alloy steel body with Inconel alloy seat and ball. ASME B and PVC Section I ‘V’ code Stamp on once through boilers and Non-code Section. The 3500 EBV helps ensure safe performance by matching the seat bore diameter to the optimum capacity requirement. In situations where open/close actuation is acceptable, the EBV can also be used to assist with startup and shutdown venting Providing Rugged Precision The guided yoke design of the 3500 EBV offers rugged construction and ensures positive and precise guiding of the actuator, stem and ball. The weight of the actuator is fully supported by the yoke, and the removal of side loading on the stem eliminates excessive wear of the packing stem and actuator.

fact sheet LEDEEN* Actuator Ledeen Actuator The Consolidated 3500 EBV employs a high quality scotch yoke actuator offering several design features not typically found on pneumatic actuators installed in power stations. All of the Ledeen actuators’ innovative design features help ensure a long service life. Providing the foundation of the Ledeen actuator, the rugged frame is well suited for developing and transferring torque to the valve. The non-pressurized, weatherproof frame ensures that the rotary seals on the output shaft will not contribute to a pressure leak that would require...

fact sheet Features and Benefits Control Package Control Station (Type 2537) The Consolidated 3500 EBV’s control package has been enhanced with several new components. The positioner monitor’s explosion-proof (NEMA 4, 4X, 7, 9 rated) aluminium enclosure is equipped with two mechanical switches and a highvisibility monitor for instant recognition of valve position up to distances of 150 feet (45.72 m). The solenoid valves are mounted directly onto the position monitor housing. In addition, optional switches can be added to send a valve position signal to the distributive control system (DCS)...
