Overview
The ASCO Series 290/8290 piston valve is a pressure-operated, direct acting angle-body piston solenoid valve built for demanding applications. Its straight-through body design is available in bronze or stainless steel. This unit features a bronze construction, making it resistant to corrosion and suitable for harsh industrial environments. The valve is suitable for general service applications (air, inert gas, water, oil, and light slurries), plus steam, hot water, and auxiliary fluids within the food and beverage industry.
Key Features
- 2-way direct acting valves available in normally closed or normally open constructions
- Available in NPT sizes from 3/8″ to 2½″
- Suitable for air, inert gases, water, oil, light slurries, steam up to 366 °F, and hot water
- Rugged water-tight actuator made from tough fiber composite and protected with a double O-ring seal
- Spring-loaded stem seal: FKM fluoroelastomer wiper keeps harmful grit way from the stem area
- Optional features include a visual/electrical position indicator or a stroke limiter
Technical Specifications
This bronze angle body piston valve is engineered for industrial-grade performance with proven durability in demanding service applications.
