Edward Valves                    

Edward valves have been designed to withstand temperatures exceed 1000° F and pressures surpassing 10,000 psi. In critical service conditions, the Edward valves don’t just meet standards, but 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, high pressure services.

The company has taken a conservative approach to valve design 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 the development of extremely high flow efficiencies in all Edward valves. Specifically, the product offers unique design advantages on various product lines, such as the 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.

Edward has produced quality valves since 1904, and today, as industrial companies become increasingly aware that operating expenses are part of total cost, they can count on Edward valves to outlast other substitutes.

Edward forged valves are produced on a fully automated line, with CNC machining centers providing precise process control. The company maximize cast steel quality by producing 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. The production personnel have an average 20 years in the industry, and 15 years with Edward Valves! This exceptional experience level allows an extra degree of precision that can make a very real difference in the field. Finally, it’s the people at Edward valves, along with their procedures for quality assurance and lot traceability, that have earned Edward Valves the ASME N stamp, certifying our Raleigh, North Carolina, manufacturing facility for nuclear service valve production.
