A double contained gully.

The KVDC 215/4”/6” Gully is a Double Contained version of the KV215 Gully with a 4” outlet surrounded by a secondary 6”SCH10 pipe.
They are designed for use primarily in Pharmaceutical factories but are sometimes used in beverage plants with very high sugar or acid concentration. They are also very important for laboratories where leaks in drainage could affect the water table.
They are used in both light duty and very heavy duty trafficked areas (depending on the grating chosen). The KHDC 215/4”/6” standard gully takes 10 mm thick gratings as well as 3 mm thick covers that are made to sit in a 10 mm recess (Perforated Gratings, Sealed Gratings).
The KHDC 215/4”/6”DS version of this gully (DS = Deep Swage) takes all 25 mm deep gratings offered by Kent (Mesh, Factory Ladder, Gratings).
Generally, a 4” or 6”SCH10 outlet is required because these are most popular with American Multinational Pharmaceutical companies who have scheduled stainless steel pipework to connect to, but this can easily be substituted for a 110or 160 mm outlet pipe. It is trapped as standard with the Kent Weir Trap.
Foul air traps:
The bottom outlet gullies use a Bell Trap (also referred to a Dome or Mushroom). A 65 mm water seal is created (complies with EN 1253). This grips firmly to an upstand which is an integral part of the gully body. It is easily removable giving clear access for rodding and cleaning. Chains can be attached to traps to ensure they are not lost.
The side outlet gullies use a weir trap system. A 50 mm water seal is created (complies with EN 1253). This is a fully integral part of the gully body and contains a removable bung for easy rodding. In special circumstances, a hinged self-sealing stainless bung can be provided.

Standard product features
Size (h x internal width x external width):
Base flanges are available with flange connections i.e. 4” / 6” / 8” ANSI B 16.5 or BS 4504 or to suit polypropylene flanges. Consult manufacturer for details.
An extensive range of gratings is available, consult technical literature for details.
Filter baskets can be incorporated into bell traps or separated for deeper gullies. For a higher flow rate, a deeper gully with separate traps and filter baskets are used. The filter basket can also be chained to avoid loss.
