1200 DA – Unidirectional

The Model 1200 DA knife gate valve is an Unidirectional wafer valve designed for industry in general.
The main features of the valve:

• Cast body of one integral piece with internal guides to support the knife.
• Seating wedges help the knife to close against the body and seat.
• Directional arrow in the body showing the correct mounting position.
• High flow rates with low pressure drop
• Internal design avoids any build up of solids that would prevent valve from closing
• Gate with rounded edges prolongs the working life of the rings and packing.
• Recommended for water with maximum concentration of solid of 5%.

* Valves manufactured following European Pressure Equipment Directive PED 97/23/CE.
