Angle seat valves improve safety, reliability and performance

Emerson has expanded is range of angle seat valves with the Asco Series 290D, offering new capabilities and best-in-class flow to optimise processes in more applications.

After 25 years of proven use in the field, Emerson identified key opportunities to optimise this series for new and existing markets. The robust, modular design of the expanded 290 Series comes with a new array of valve bodies and actuator materials, fittings, functions, certifications and accessories. Significant features include fugitive emissions certification, switch box with IP69K protection level and safe actuator dismounting.

These customisations improve process efficiency and safety while reducing costs in many applications, including industrial, food and beverage and specialty chemical.

In the new Asco Series 290D, a wide range of valve bodies, actuators, options, control box and certifications are provided for enhanced application versatility. Built-in modularity makes it possible to interchange different actuators on the same body for on-site modification of the valve characteristics after assembly. Both IP66 and IP69K enclosures are available for either indoor or outdoor use. The new Series 290D is also suitable for a wide range of media, including aggressive fluids, steam, gas, vacuum and superheated water.

The 290 Series is designed with a highly reliable fluid control mechanism engineered for exceptionally safe shutdown. With valves accounting for over 51% of fugitive or irregular emissions, the new design helps reduce fugitive emissions and minimizes risks to workers and the environment. While the new Asco Series 290D actuator requires almost no maintenance, further safety-enhancing features include safe actuator dismounting, which ensures maintenance workers are protected during potentially dangerous actuator dismantling procedure.

Featuring what Emerson claims is the highest flow rate (Kv) in its class and proportional control for accurate regulation, the Series 290 helps improve production efficiency. At the same time, a long operating life extends the intervals between maintenance, while the inherently rugged design is built to withstand the demands of challenging operating environments and aggressive media.
