Description
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
- Watertight Types 1, 2, 3, 3S, 4, and 4X and explosion-proof and watertight Types 3, 3S, 4, 4X, 6, 6P, 7, and 9 offer reliable operation in challenging environments
