CHOICE OF THE VALVE

RWV offers ball valves made of different materials: brass, lead free* brass, Dezincification Resistant (DZR)
brass, lead free DZR brass, bronze, and stainless steel. We recommend using valves made of a material
suitable for the specific application. Stainless steel, bronze and DZR brasses are recommended to reduce risk
of de-zincification and stress corrosion. Details of the materials used for each model are listed in the specific
valve technical sheet. Please refer to your local water authority for compatibility with brass products. RWV
cannot be held responsible for failures caused by the quality of the water in combination with an unsuitable
material chosen for the valve.

*

Federal Safe Drinking Water Act – SDWA 2011 standards have determined “lead free” as having less than 0.25% of wetted surface area.

PRESSURE AND TEMPERATURE RATINGS

Specific information on pressure and temperature ratings of each valve model are provided in the RWV
technical sheets, those can be obtained through RWV site or by contacting RWV. All contact information is
provided in the last page of these instructions.
The operative conditions given in the tech sheets are intended for non-shock operating conditions: water
hammer, impacts, stress loads, corrosive or erosive external environmental elements and the transport of
fluids with abrasive properties should be avoided.

VALVE INSTALLATION

Prior to installation, verify the valve is suitable for the pressures, temperatures, operating fluids and
environment in which it will be installed. It is the responsibility of the installer and/or of the facility designer to
ensure that the application does not exceed the limits of pressure and temperature of the valve and is carried
out in accordance with local current laws and regulations.
All models referred to in the above table can be installed in any position (vertical, horizontal, inclined), with
flow going in both directions. The position chosen for the installation should allow for accessibility to the valve
during operation, inspection and maintenance.
Pipe ends should be void of any burrs and not protrude inside the bore or obstruct any part of the flow (it’s
advisable to flush the line after installation or after performing maintenance on the system).
Do not subject the valve to any torsion, bending or tension. We recommend the use of pipe brackets. Pipe
brackets should be installed at a distance suitable to properly support the valve. Do not to overload the valve
with any unexpected additional stresses

Threaded connections

The valves shall be installed on pipes using, if necessary, a sealant suitable for the application and the
expected type of fluid.

• The pipe threading shall be in accordance with the applicable standard requirements (please refer to the
valve technical sheet). The pipe threading must be free of damage that could impair the correct coupling
with the valve and the outward seal.

• Additional stresses on the body to body-end junction must be avoided during installation. A pipe clamp or
key wrench must always grasp onto the hexagon/octagon portion of the threaded end that needs to be
screwed to the pipe. In order to avoid additional stress on the valve be careful not to tighten the pipe at an
excessive distance from the threaded area.

• Avoid screwing male threaded pipes too far into the valve. This could result in damage to the valve seats,
resulting in leakage once the valve is operational.

• When installing a tailpiece, slide the union nut over the pipe before mounting to prevent interference
between the tailpiece and union. Make sure all seals/o-rings are in place and not damaged.

Sweat connections

RWV sweat connections are designed to be soft soldered.

• Valves contain polymer materials such as o-rings and PTFE seals. These seals can be damaged by
excessive heat, therefore the use of heat sinks (for example a wet towel around the valve) is required. The
flame must be directed away from the center of the valve body.

• Ball valves must be placed in the closed position prior to soldering. After the installation wait for the valve
to cool to room temperature before operating it.

• Make sure that the cut on the pipe is as square as possible and no burrs or rough edges are present. Clean
both the valve socket and pipe end with a suitable tool until they are made bright.

• Coat both the valve socket and pipe with non-corrosive solder flux. In cold weather this should be done with
the parts at ambient temperature. After applying the flux, slide the pipe to the shoulder of the socket then
rotate a few times to insure flux properly covers the connection prior to soldering
