Asco 8221G33 2" Slow Closing Solenoid Valve N/O 5-150 PSI Water/Oil

The ASCO 8221G33 2" Slow Closing Solenoid Valve 5-150 PSI Water/Oil controls fluid flow through an electrically actuated mechanism that responds to control signals by shifting an internal plunger to regulate passage between inlet and outlet sections within HVAC systems. In its normally open state, flow is maintained until energized, after which the mechanism gradually transitions to a closed position to reduce sudden pressure changes in the line. The slow-closing action helps stabilize flow behavior during shutdown sequences for water or oil circuits. Installed in compatible piping assemblies, it supports controlled flow regulation and smooth operational transitions across repeated actuation cycles.
