ASCO 551 Solenoid Spool Valve
The ASCO Series 551, also known as 8551, is a line of 1/4" 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 ¼-inch NPT and BSP connections. It is suitable for the harsh conditions found in chemicals, refining, food & beverage applications and life science processing.
Features
1.Available in two versions, mounted directly to actuators with NAMUR interface per VDI/VDE 3845 or threaded to mount on the pipe
2.Valve body in Aluminum, Brass, or Stainless steel 316L
3.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
4.Low-power constructions are ideal for remote and alternative power locations
5.Integral breather block vents to spring side of the actuator to exhaust, preventing corrosion
