Next-generation ASCO Series 290D pressure-operated piston valves from Emerson have been optimized for demanding combustion applications. New features improve process efficiency, reliability and safety while reducing costs. An all-stainless-steel valve head resists corrosion, offering protection from harsh environments and aggressive media. Options with EN 161 and EN 16678 certifications makes the valve globally viable for use in gas-burning applications, and flanged connection options provide a tight seal. A more rugged smart positioner offers additional functionality and approvals. The valve has a low ambient temperature rating, down to -40° F, providing reliable operation even in extreme climates. An increased MOPD of 20 psi and shutoff up to 75 psi offer high pressure tolerance, ensuring reliable operation at high pressures and preventing gas leakage. Suitable for use with a wide variety of media, including aggressive fluids, steam, gas, vacuum and superheated water, the versatile piston valve comes in many options, certifications and characteristics.
