ASCO 553 Series Solenoid Spool Valve

Brand: ASCO
The 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 1/2-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 vents 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
  • All ports of NAMUR on the same side for a better water , DUST protection
  • Available will all Explosion proof solenoids: Ex d, Ex mb, Ex ia/Ib, Ex e mb, NEMA
