2 Way Solenoid Valves 8221 Series

The solenoid is an electromagnetic part of a valve, comprised of a coil, coretube, core and enclosure. ASCO Redhat brand offers the worlds largest selection of 2-, 3- and 4-way solenoid valves, designed to handle the most demanding fluid control applications.
Asco 4 Way 2 Position Air-Only Solenoid Valves
General Description
These valves are designed to eliminate water hammer problems experienced i many water and light oil systems. Their unique slow closing construction reduces the pressure spike which causes water hammer to a level eliminating the need for suppressors or other controls.

Evaluations per Fluid Controls Institute Inc. Standard FCI-82-1 (Recommended Methods for Testing and Classifying the Water Hammer Characteristics of Electrically Operated Valves) have classified these valves as follows:

Notes: 1 - Valves require a 5 psi Mimimum Pressure Differential to open. Once open, they remain open with 3 psi differential pressure.
2 - Refer to Steam/Hot Water Valves Series for hot water service.
3 - On 50 Hertz service, the watt rating for the 6.1/F solenoid is 8.1 watts.
