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 Flowserve Edward forged and cast steel valves have become the specified choice for power plants, process facilities, and other high-temperature, high-pressure services. Conservative Design Flowserve 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...

Designed With an Eye on Your Bottom Line In-house computer-aided design and finite-element method capabilities give our engineering staff powerful tools to develop reliable valves for critical service applications. CAD generated graphic models undergo FEM analysis to determine that stresses are within acceptable limits. Dynamic simulation of valve operation also helps assure reliability of Edward valve performance. Prototyping is just as important, and rigorous proof testing is a mainstay of Edward valve design. Before we approve a valve for production, we put it through hundreds, even thousands,...

Testing Beyond Code Requirements At Flowserve Edward Valves, quality assurance starts with meeting code requirements. Valves are manufactured to ANSI B16.34 (Standard, Limited and Special Classes), including standards for: • Minimum wall thickness of valve body. • Body, bonnet and body-bonnet bolting to specified ASTM material standards. • Hydrostatic shell testing at 1.5 times the 100°F rating of the valve. From there, Flowserve Edward Valves goes on to exceed the code, with higher test standards and an additional battery of tests performed on every type of valve we make, using in-house test...

A History of Firsts Feature Body-guided disks on globe and angle valves Minimize wear and ensure alignment for tight sealing. Integral Stellite hardfaced seats in globe and angle valves Permit compact design and resist erosion. Hermetically sealed globe valves with seal-welded diaphragms Prevent stem leakage in critical nuclear plant applications. Equalizers for large check and stop-check valves Ensure full lift at moderate flow rates, and prevent damage due to instability. Compact pressure-seal bonnet joints Eliminate massive bolted flanges on large, high-pressure valves. Qualified stored-energy...
