AGV 25

AGV 25 - UNIDIRECTIONAL FLANGED KNIFE GATE VALVE

DESCRIPTION

  • One-piece cast body with guides to support gate and seat wedges.
  • Provides high flow rates with low pressure drops.
  • Various seal and stuffing materials available.
  • Across flats in accordance with AAP Techniks standard.
  • An arrow is marked on the body indicating the flow direction

GENERAL APLICATIONS

This knife gate valve is suitable for liquids that contain a maximum of 5% suspended solids. If it is used for dry solids in gravity feed applications it should be installed with the arrow on the body pointing in the opposite direction to the flow.


Designed for applications such as:

  • Paper industry
  • Mining
  • Silo discharge
  • Chemical plants
  • Pumping
  • Food industry
  • Sewage treatment


In all these applications it is recommended to install the val- ve once the fluid has been filtered, to remove the solids or large particles that it contains.

SIZES

ND50 to ND2000

WORKING (P)

ND50-150 10kg/cm2 ND350-400 5kg/cm2
ND200 8kg/cm2 ND450-600 3kg/cm2
ND250-300 6kg/cm2 ND700-1400 3kg/cm2

The indicated work pressures will only be valid following the direction of the arrow marked on the valve. Due to the valve’s design with gate support guides, 30% of these pres- sures can be applied in the opposite direction to the arrow without causing any damage to it. In these circumstances the valve is not watertight. An additional series of supports is necessary in order to achieve watertight integrity in these conditions.

  • (ATEX) CAT.3 ZONA 2 y 22 GD.

QUALITY DOSSIER

All valves are tested hydrostatically at AAP Techniks and material and test certificates can be supplied on request.

  • Body test = working pressure x 1.5
  • Seal test = working pressure x 1.1
