The ASCO Series 401, also known as 8401, is a line of pilot-operated air slide valves designed for air and inert gas service in heating equipment applications.

The aluminum valves incorporate a unique sliding and sealing member that provides a durable and non-stick sealing method. Optional flow control regulates cylinder speed in either direction and permits adjustable Cv from 0.2 to 0.8.
Features
  • Dual solenoid versions hold last position, even after loss of electric power. Solenoid may be energized momentarily (1/10 second) or continuously
  • Standard manual operator both momentary and maintained
  • Sub-base and manifold mounting for installation flexibility; direct-mount constructions are available
