Products 8298 air-operated ASCO Emerson piston valves Series 298

The ASCO Series 298 from Emerson, also known as 8298, air-operated piston valves are built to withstand the challenges of saturated steam, superheated water, and corrosive fluid applications.

The stainless steel piston valve has up to a 43% higher pressure rating than competitive products, the company says.

The valve is suitable for indoor and outdoor applications such as rubber vulcanization, tire presses, industrial autoclaves, foundries, food and beverage equipment, and chemical processing.

The valves are constructed from temperature-resistant materials for an operating range of -25° to 180°C and are resistant to thermal shock.

Anti-water hammer design and back pressure protection ensure reliable operation, it adds, and easy disassembly minimizes maintenance and cleaning costs.

In addition, bidirectional flow allows for process flexibility and a standard visual position indicator is said to enable easy monitoring.
