Series LF007Double Check Valve Assemblies

Sizes: 1 ⁄ 2" – 3" (15 – 80mm)Series LF007 Double Check Valve Assemblies shall be installed atreferenced cross-connections to prevent the backflow of pollutedwater into the potable water supply. Only those cross-connectionsidentified by local inspection authorities as non-health hazard shallbe allowed the use of an approved double check valve assembly.

The LF007 features Lead Free* construction to comply with LeadFree* installation requirements.

Check with local authority having jurisdiction regarding verticalorientation, 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 Universityof 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

Specifications A Double Check Valve Assembly shall be installed at each notedlocation. The assembly shall consist of two positive seating checkmodules with captured springs and rubber seat discs. The checkmodule seats and seat discs shall be replaceable. Service ofall internal components shall be through a single access cover

secured with stainless steel bolts. The Double Check Valve Assemblies shall be constructed using Lead Free* cast coppersilicon alloy. Lead Free* Double Check Valve Assemblies shallcomply with state codes and standards, where applicable, requir-ing reduced lead content. The assembly shall also include tworesilient seated isolation valves; four top mounted, resilient seatedtest cocks. The assembly shall meet the requirements of ASSEStd. 1015 and AWWA Std. C510. Approved by the Foundation forCross-Connection Control and Hydraulic Research at the Universityof Southern California. Assembly shall be a Watts Series LF007.
