Edward Valves EV100 5th Edition Introduction A
High Performance For Critical Service Temperatures that can exceed 1000° F. Pressures surpassing 10,000 psi. In critical service conditions, you can’t take chances. You don’t just meet standards, you exceed them. That’s how Edward forged and cast steel valves have become the specified choice for power plants, process facilities, and other high-temperature, highpressure services. Conservative Design Edward Valves takes a conservative approach to valve design. We meet all applicable codes and standards, but we go beyond that...with finite element stress analysis of critical areas and rigorous proof testing. Edward valves are built to take punishment! And our extensive testing has also allowed us to develop extremely high flow efficiencies in all our valves. You’ll find other unique design advantages on our various product lines, such as our Equiwedge gate valves, with a two-piece wedge gate assembly which adjusts automatically to any angular distortion of the body seats. And many other design features, now considered industry “standards,” started on the drawing boards at Edward Valves. Precision Manufacturing Edward Valves also exceeds industry standards on the factory floor. Our forged valves are produced on a fully automated line, with CNC machining centers providing precise process control. And we maximize cast steel quality by producing our valve body castings using a directional solidification process from patterns designed by our own technicians. This process assures high strength void free castings for uncompromised quality. Even with the most advanced equipment, we feel our people make the real difference at Edward Valves. Our production personnel have an average 20 years in the industry, and 15 years with Edward Valves! This exceptional experience level allows us to achieve an extra degree of precision that can make a very real difference in the field. Finally, it’s our people, along with our procedures for quality assurance and lottraceability, that have earned Edward Valves the ASME N stamp, certifying our Raleigh, North Carolina, manufacturing facility for nuclearservice valve production. Flow Control Division Edward Valves Lower Total Costs Those tough standards have carried over into every valve we manufacture. Whether it is for nuclear service or not, we design and build our valves to last at least 40 years. That means not only are they tough, but they are designed with easy maintenance in mind. Considering the cost of valve failure, Edward Valves quality is clearly worth specifying. That’s been true since 1904, when the first Edward valve was made. Today, as industrial companies become increasingly aware that operating expenses are part of total cost, the choice becomes both more clear and more critical than ever.
