Winegrowers Supplies  -  Valves, adaptors and hose connectors


    Butterfly-valve with sealing cap:-
  DN40 female to DN40 male, 130 Euros   (Note: DN40 to 1¼" bsp is not available)
  DN50 female to DN40 male or 1¼" bsp male, 140 Euros
  DN threads (Deutsches Institute für Normung) are also called DIN or NW; the size specification is below.

    Gr.37/70 flap-valve with sealing cap, 80 Euros

      Racking-pipe+butterfly-valve for use through
                                             Gr.37/70 flap-valves, ending in DN40 male thread, 230 Euros

You need only one of these, to use through the flap-valve fitted to each tank, simply pushing it in when you need to rack. When you've racked off all the liquid down to this level,
just below the man-way door, you open the man-way and hold the racking pipe by hand to suck out the remainder of the clear liquid.

Decanter arm: rotatable racking pipe, for use through DN40 or DN50 fittings:-

      DN40 220 Euros, DN50 230 Euros

A decanter arm cannot be removed from a full tank. It can be unscrewed and removed from an empty tank and then inserted in another empty tank;
consequently each full tank needs to have it's own decanter arm installed.

BSP (British Standard Pipe) threads can be parallel or tapered. Tapered threads are for permanent connection only and are considered 'not hygienic'. Parallel threads are hygenic, threads must be sealed with ptfe tape for permanent connection (for example valves), or will be fitted with a rubber seal if the fittings are to be removed regularly (for example hose-connectors).

RJT (Rubber Joint Thread), sometimes known British Standard Milk thread. Still used widely in breweries.

The union consists of a hexagon nut in AISI-304 stainless steel, a weld-male-thread part and a pressed liner both in AISI-316; the liner is pressed from 1.5 mm thick sheet.
A pressed blank cap can be used, in place of the normal liner, to make a blank-off fitting.
The rubber joint ring is an "O" type (6.6 mm diameter) and is normally made of Nitrile rubber.
