Numatics 521 Series Mini-Spool Valves

Brand: ASCO
The ASCO Numatics Series 521 is a line of solenoid air-operated, mini-spool valves that are ideal for piloting pneumatic cylinders.
 
The valves have high-quality coils resistant to heat and moisture and suitable for high ambient temperatures and harsh environments.
 
They can be mounted on joinable subbases for manifold applications.
 
The ASCO Numatics 521 valves are suitable for automotive, case packing, packaging, and tyre manufacturing applications.
Features
  • Anodised aluminium G1/4-tapped body with NBR seals for extended service life
  • Non-breathing construction where the spring return chambers of the single- or double-acting actuator are collected with the solenoid valve exhaust
  • Handles lubricated or non-lubricated air or neutral gas
  • Ambient temperature range 5° C to 50° C
  • Satisfies all relevant EU Directives
