One-piece cast unidirectional valve with body with guides to support the knife gate and sealing wedges. The interior of the body is tapered, providing more space. This means that the solids stored inside can be easily released when the valve is closed.
Designed with full passage to provide large flows with low pressure losses.
The body’s internal design prevents any build up of solids in the seat area.
High flow rates with low pressure drops.
Multiple sealing and packing materials.
Face-to-face distance in accordance with CMO Valves standard.
An arrow is marked on the body indicating the flow direction.
Manual drives (handwheel, lever, geared motor with handwheel) and actuated drives (pneumatic, hydraulic, and electric drives) are available, depending on application requirements.
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:
From DN50 up to DN1200
*Others ND on request
* Other pressures, consult.
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. Achieving watertight integrity under these conditions requires additional brackets; contact CMO Valves in such cases.
