Reduced Pressure Zone Assemblies

Sizes:

⁄4" – 2"

Series 009 Reduced Pressure Zone Assemblies are designed

to protect potable water supplies in accordance with national

plumbing codes and water authority requirements. This series

is designed to protect drinking water supplies from dangerous

cross-connections in accordance with national plumbing codes

and water authority requirements for non-potable service appli-

cations such as irrigation, fireline, or industrial processing.

This series features two in-line, independent check valves, captured

springs and replaceable check seats with an intermediate relief

valve. Its compact modular design facilitates easy maintenance and

assembly access. Sizes

⁄4" – 1" shutoffs have tee handles.

Features

• Single access cover and modular check construction

for ease of maintenance

• Top entry - all internals immediately accessible

• Captured springs for safe maintenance

• Internal relief valve for reduced installation clearances

• Replaceable seats for economical repair

• Bronze body construction for durability

⁄4" – 2"

• Ball valve test cocks — screwdriver slotted

⁄4" – 2"

• Large body passages provides low pressure drop

• Compact, space saving design

• No special tools required for servicing

Specifications

A Reduced Pressure Zone Assembly shall be installed at each

potential health hazard location to prevent backflow due to back-

siphonage and/or backpressure. The assembly shall consist of an

internal pressure differential relief valve located in a zone between

two positive seating check modules with captured springs and

silicone seat discs. Seats and seat discs shall be replaceable

in both check modules and the relief valve. There shall be no

threads or screws in the waterway exposed to line fluids. Service

of all internal components shall be through a single access

bronze cover secured with stainless steel bolts. The assembly

shall also include two resilient seated isolation valves, four resilient

seated test cocks and an air gap drain fitting. The assembly shall

meet the requirements of: USC; ASSE Std. 1013; AWWA Std.

C511-92; CSA B64.4. Shall be a Watts Series 009.
