ASCO Series 298 Stainless Steel Piston Valve

Brand: ASCO
The ASCO Series 298, 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 and provides superior performance in OEM equipment. The valve is well suited for indoor and outdoor applications such as rubber vulcanization, tire presses, industrial autoclaves, foundries, food and beverage equipment, and chemical processing.
Features
  • Constructed from temperature-resistant materials for a wide operating range of -13° F to 356° F (-25° C to 180° C)
  • High-performance, maintenance-free stuffing box is resistant to thermal shock
  • Compact and light weight design reduces installation cost
  • Anti-water hammer design and back pressure protection ensure reliable operation
  • Easy disassembly minimizes maintenance and cleaning costs
  • Bidirectional flow allows for process flexibility
  • Standard visual position indicator enables easy monitoring
