Personnel involved in the installation or maintenance of valves should be constantly
alert to possible damages caused by an improper handling of the valve.
Description
The automatic direct acting PRV Mod. VRCD-FF consists of a upstream pressure balanced single
seat globe pattern valve, piston actuated, and equipped with a spring located in the cover to impart
the force necessary for the proper working. By means of a compensation chamber the valve will
reduce and stabilize the downstream pressure regardless of variations in demand and upstream
pressure fluctuations. The operating principle is explained on the technical catalogue, for further
details please contact CSA and/or its local rep. The special design of CSA with built in self cleaning
piston technology guarantees long lasting performances with a dramatic reduction of the
maintenance time, minimizing the risk of friction and malfunctioning.
Handling and Storage
Lifting the valve improperly may damage it. Lift the valve with slings, chains or cables fastened
around the valve body. Do never lift the valve by the adjusting screw and by the threaded
connection. If installation will be delayed, place valve indoors in secure, weather tight storage. If
temporary outside storage is unavoidable, make sure a vermin proof rain cover is secured
around/over the valve to keep off rain and mud. Skid and set the assembly on a flat, solid, and well
drained surface for protection from ground moisture, runoff and pooled rain water. Do not leave the
valve exposed to high humidity and excessive temperature conditions and do not remove the
plastic taps prior to the installation.
