The louver damper is composed of various blades which each turn on the central shaft. The ends are joined to the pipes via flanges. Normally, the louver damper is supplied as one piece, except in those applications in which the dimensions of the equipment require special transport.
Construction
The body of the PL damper is machine welded and can be made of different materials. The standard construction sizes range from 150×150 mm (minimum) to 3000×3000 mm although larger sizes are available on request. The blades are made flat, with reinforcing ribs and are supported on two semi‐shafts. The flat blade system is sufficiently rigid for the working pressures of these valves and they do not produce significant load losses.
The PL dampers have two types of seals. Depending on the application you can choose between: Swing‐thru (97% seal), for environments with high dust concentrations, the metal/metal seal (99% seal) and the step‐seat joint for other applications that require greater watertight integrity, reaching 100% with air chamber sealing.
The SC damper is composed of a blade which turns on a shaft located on one side (like a gate). The ends are joined to the pipes via flanges. Normally, the SC damper is supplied as one piece, except in those applications in which the dimensions of the equipmentrequire special transport.

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 CMO Valves standard. It has an arrow on the body indicating the flow direction. Usually mounted under a hopper, to prevent any kind of solids accumulating on the seat, has a special body design and it is assembled with the body arrow in the same direction as the fluid. When a knife gate valve remains open for long periods of time and the body’s internal walls are parallel a very large torque is usually required to close it. However, the inside of the body of model F is cone‐shaped, which provides greater space and, this way, when the valve is closed the solids stored inside it can be easily removed.
This knife gate valve is suitable for working with dry products like powder and grain. It is generally used for gravity discharge of dry solids. Designed for the following applications: -Mining ‐Silo emptying ‐ Electrical power stations ‐ Chemical plants ‐ Food Industry

Bidirectional knife gate valve. Valve suitable for use as end-of-line.The GA valve body is a single monobloc piece. Stainless steel through-conduit gate. Two rubber sleeves. The main characteristic of this slurry valves is that it provides a full continuous flow. This means that in open position it produces no cavities and there is no turbulence in the fluid. The stem protection hood is independent from the handwheel securing nut, this means the hood can be disassembled without the need to release the handwheel. This advantage allows regular maintenance operations to be carried out, such as lubricating the stem, etc. The CMO valve stem is made from stainless steel 18/8. This is another additional benefit, since some manufacturers supply it with 13% chrome, which quickly rusts. The operating wheel is manufactured in nodular cast GJS-500. Some manufacturers supply it in common cast-iron, which can lead to breakage in the event of very high operation torque or a bang. The yoke has a compact design with the bronze actuator nut protected in a sealed and lubricated box. This makes it possible to move the valve with a key, even without the handwheel (in other manufacturers’ products this is not possible). The pneumatic actuator’s upper and lower covers are made of GJS-400 nodular cast iron, making them highly shock resistant. This characteristic is essential in pneumatic actuators.
Thats knife gate slurry valves are suitable for working in the mining industry, in loaded fluid transport lines such as water with stones, sludge, etc, and, in general, for abrasive fluids in the chemical industry and waste water.
