AGV 24 - UNIDIRECTIONAL KNIFE GATE VALVE
DESCRIPTION
- One piece cast body with guides to support gate and seat wedges
- Provides high flow rates with low pressure drop.
- Various seat and packing materials available.
- Face to face dimension 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 emptying
- Chemical plants
- Pumping
- Food Industry
- Sewage treatment.
SIZES
DN50 to DN1200.
WORKING PRESSURE (∆P)
| DN50 - DN250 | 10 bar |
|---|---|
| DN300 - DN400 | 6 bar |
| DN450 | 5 bar |
| DN500 - DN600 | 4 bar |
| DN700 - DN1200 | 3 bar |
The mentioned working pressures are just valid for the pressures 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 incorporate additional supports.
STANDARD FLANGES
- ENI092 PN10.
- ASME B16.5 (clase 150).
OTHER COMMON FLANGES
- PN6.
- PN16.
- PN25.
- BS “D” & “E”.
- JIS10K.
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
