Brand: ASCOThe ASCO Series 553, also known as 8553, is a line of 1/2" 3-way and 4-way compact solenoid spool valves that are ideal for controlling air or inert gas in challenging environments.
The valves’ unique design combines hard T-seals and flexible O-rings that provide bubble-tight shutoff, dirt resistance, and multi-million-cycle reliability.
The 551 Series comes in anodized aluminum, brass, and stainless steel bodies with ½-inch NPT and BSP connections.
It is suitable for the harsh conditions found in chemicals, refining, food & beverage applications, and life science processing.
Features- Available in two versions: mounted directly to actuators with NAMUR interface per VDI⁄VDE 3845 or threaded to mount on the pipe
- Valve body in Aluminum, Brass, or Stainless steel 316L
- Exhaust ports are pipeable, providing better protection against harsh environments
- DIN, watertight, and explosion-proof solenoids are available for use in mission-critical and hazardous areas
- Low-power constructions are ideal for remote and alternative power locations
- Integral breather block vent to spring side of the actuator to exhaust, preventing corrosion
- Single- and dual-solenoid constructions are available that mount in any position
- Compatible to Functional safety loop up to SIL 3
