Red Valve Tideflex Series - Installation; Inspection of Valve; Valve Orientation; Pipe Dimensions

INSTALLATION
1. Inspection of Valve
Check inside diameter of pipe section for rough or damaged
areas. Surface should be uniform and relatively smooth. Long
gouges or cracks may allow water to pass and should be lled
prior to installation. The exterior of the Series 37G should
have a rough texture resembling a cloth pattern. This will help
the valve grip the walls of the pipe.
2. Valve Orientation
The valve shall be installed with the bill in the vertical position.
Valves to 18" (nominal) are supplied with a single clamp. The
clamp turnbuckle should be oriented at top dead center.
Valves 24"—48" (nominal) are supplied with two clamps. The
turnbuckles should be oriented 180˚ apart. Valves 60"—72"
(nominal) are supplied with three clamps. Turnbuckles should
be oriented 120˚ apart.
3. Pipe Dimensions
Every Series 37G is designed and built to t into a specic
pipe inside diameter. Different pipe materials such as
concrete, HDPE, steel, and PVC have different. I.D.
dimensions for the same nominal pipe size. Do not attempt
to install a Series 37G into a pipeline for which it was not
intended.
4. Preparation
The Series 37G uses expanding clamp(s) to exert pressure
outwards on the walls of the valve to "wedge" it in place within
the pipe. The walls of the pipe should be clean and free of
debris prior to installation.
5. Securing
The valve should be inserted fully into the pipe so that no
part of the cuff or bill extends outside the pipe. Ensure that
the valve is not "slanted" at an angle, with the bill pointing
upwards or downwards. The valve centerline should be
parallel to the pipe centerline.
Tideex
®
recommends pinning the Series 37G on all
installations. See below.
Four pre-drilled holes are provided in each expansion clamp.
At least one clamp should be pinned. On exposed pipe, holes
can be drilled through the valve and pipe, and a bolt run
through secured with a nut. For buried pipe, silicon or similar
sealant should be used to seal bolts.
