KVCRP265/4”RD

Application

  • Suitable for use primarily in Pharmaceutical factories.
  • They can be used in both light duty and very heavy duty trafficked areas (sealed gullies are most often used in laboratories or cleanrooms which are limited to pedestrian traffic - however the 10 mm top plate makes it possible to drive heavy factory traffic over these gullies).

Description

A stainless steel industrial gully. The KVCRP265/4”RD is a sealed pneumatic cleanroom gully. It has a round body, round top and bottom outlet and can be used for heavy duty areas with high flow rates.

It has a pneumatic opening system that allows it pop open from a remote switch. The gully must be connected to a pneumatic supply and this supply is controlled often by a rotary switch on a nearby wall or remotely in a maintenance control centre.

The gully solves the problem of cleaners unsealing gullies and not resealing them properly. It also is used to pop open automatically when connected to a sprinkler system. This is a sealed cleanroom gully with a strong positive seal created by machining away a 10 mm groove from a 20 mm top plate. A 10 mm top plate with a recessed ‘O-ring’ creates the seal.

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.

Features and benefits:

  • Manufactured from grade 1.4301 (304) or 1.4401 (316) stainless steel to BS EN 10088.
  • Strong.
  • Meets the requirements of BS EN 1253 Loading Class L15/ R50/ M125/ N250/ P400. This gully can be subjected to very heavy loads but must have the correct heavy duty grating to achieve these loads.
  • Usable in both heavy and light duty areas.
  • Suitable for internal factory drainage and external civil drainage projects.
  • The gully is often used as part of a channel system
  • In most cases a 4” or 6” SCH10 outlet is required, but this can easily be substituted for a 110 or 160 mm outlet pipe. It is trapped as standard with the Kent Bell Trap.

Applications:

  • Suitable for use primarily in Pharmaceutical factories.
  • They can be used in both light duty and very heavy duty trafficked areas (sealed gullies are most often used in laboratories or cleanrooms which are limited to pedestrian traffic - however the 10 mm top plate makes it possible to drive heavy factory traffic over these gullies).

Product Options

Flanges:

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.

Side inlets:

- Angle:

  • Side inlets can be 90° to gully body, however, they can be welded at 45° or a specific angle to suit a specific project.
  • Round Body gullies are most suitable for a higher number of side inlets at different angles.

Grating:

An extensive range of gratings are available, consult technical literature for details.

Filter basket:

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.
