Check with local authority having jurisdiction regarding vertical orientation, frequency of testing or other installation requirements.

The valve shall meet the requirements of ASSE Std. 1015 and AWWA Std. C510. Approved by the Foundation for Cross- Connection Control and Hydraulic Research at the University of Southern California.

Features

• Ease of maintenance — only one cover

• Top entry

• Replaceable seats and seat discs

• Modular construction

• Compact design

• Lead Free* cast copper silicon alloy body construction —

1⁄2" – 2" (15 – 50mm)

• Fused epoxy coated cast iron body — 21⁄2" – 3" (65 – 80mm)

• Top mounted Lead Free* ball valve test cocks

• Low pressure drop

• No special tools required for servicing

• 1⁄2" – 1" (15 – 25mm) have tee handles
