2/2

SERIES

8221

2-WAY

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:
