ASCO 8221 Series - Slow Closing Solenoid Valve

Features :

• Pilot operated, normally open or normally closed

• Snubber slows disc closing speed to protect system against water hammer damage more effectively than

other techniques

• Pressure spike due to water hammer is reduced to a point eliminating the need for suppressors or other

controls in most water systems

• Fluid Controls Institute Inc. evaluations have classified these valves:
