Knife Gate Valve – Serie AD

Product description

– One-piece cast body with guides to support gate and seat wedges.
– High flow rates with low load losses.
– Stainless steel gate.
– Various constructions materials and seal and stuffing materials available.
– Face-to-face distance in accordance with CMO Valves standard.
– An arrow is marked on the body indicating the flow direction.

Utilization

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.
• Chemical plants.
• Pumping.
• Food industry.
• Sewage treatment.

Sizes

DN80 to DN1200
*bigger diameters under request.

Working pressures

• DN 80 – DN250 = 10 bar
• DN 300 – DN400 = 6 bar
• DN 450 = 5 bar
• DN 500 – DN600 = 4 bar
• DN 700 – DN1200 = 3 bar

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 pressures 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 tightness in these conditions.
