Preval 3 - 10 L/per minute Vario Shower Valve

The new innovative PREVAL water saving product "Vario" for hand and head showers combines the advantages of a variable amount of water regulation and the specific air mixing in a product. The regulation is simple and is done without replacement or installation of additional components. For the installation and adjustment work commercially available tools are needed.
The "Vario" basically consists of an inner and an outer part. Both parts are made of lead-free brass (CUPHIN) with chrome finish. The inner part can be rotated through 360°. The two parts are fixed together by two staggered at 180° Allen screws. The outer part with threaded connection ½" IG is installed at the water inlet, the shower hose or shower head can be mounted on the threaded connection ½" AG of the inner part.

Product Description


The regulation of the desired water volume is done by simply rotating the inner part. For this, the two Allen screws are released and tightened again after completion of the regulatory. The adjustable amount of water is by default 3-10 l/min depending on the water pressure. The addition of air takes place through a lateral borehole of the inner part and is regulated by an integrated venturi nozzle. A stainless steel spring prevents unintended adjustment of the venturi nozzle. The shower hose or shower head needs to be temporarily released from the inner part of the “Vario” for the regulation process. The adjustment of the air flow is between "zero and maximum" steplessly possible. The lateral borehole is also used to drain the remaining water from the shower hose or shower head.
