AGV 27 - UNIDIRECTIONAL KNIFE GATE VALVE

DESCRIPTION

  • Unidirectional “LUG” guillotine valve.
  • Monobloc cast body with interior slides for optimum movement of the gate during operation.
  • Provides high flow rates with low pressure drop.
  • Various seat and packing materials available.
  • Face-to-face dimension in accordance with AAP Techniks standard.
  • Has an arrow on the body indicating the flow direction.

GENERAL APLICATIONS

This knife gate valve is suitable to work with liquids with a maximum concentration of solids of 6%. If used for solids, we recommend installing with the body which indicates the contrary flow direction.


Designed for the following applications :

  • Bulk transport
  • Draining plants
  • Paper industry
  • Water treatment
  • Chemical plants
  • Food sector
  • Mining

SIZES

ND50 - 2” to ND1200 - 48” (larger sizes on request)

WORKING PRESSURE (∆P)

  • ND50-2" - ND600-24" = 10kg/cm2
  • ND700-28" - ND900-36" = 6 kg/cm2
  • ND1000-40" - ND1200-48" = 4 kg/cm2

The mentioned working pressures are just valid for the pres- sures applied on the direction of the arrow market on the body. As the valve is designed with gate support guides, the valves are able to support a 30% of these pressures from the opposite direction without any damage on them. In these cases, the valves are not 100% water tight. To obtain total water tightness in these conditions, it is necessary to incor- porate additional supports.

DRILLING

DIN PN10 & ANSI B16.5 (150 LB)

OTHER COMMON FLANGES

  • DIN PN 6 : Australian standard.
  • DIN PN 16 : JIS standard.
  • DIN PN 25 : British standard.

QUALITY DOSSIER

All valves are tested hydrostatically at AAP Techniks, and material and test certificates can be provided.

  • Body test = working pressure x 1,5
  • Seat test = working pressure x 1,1
