Chief Features

Ultra-thin design, beautiful appearance, light weight and compact structure, easy to install and use.

The valve is connected by clip-on, and the structure length is short, which can reduce the weight of the entire pipeline system.

The bottom of the gate is smooth without any grooves to ensure that impurities do not accumulate.

The U-shaped sealing strip valve body is inlaid structure, which can prevent leakage caused by the movement of the sealing strip, so that the slurry valve can achieve two-way zero leakage sealing.

The sealing of the valve adopts the side sealing structure, and the two-way sealing is realized on the three sides of the valve plate through the sealing strip embedded in the valve body and keeping smooth and consistent with the surface of the valve body.

The bottom of the valve plate is a semi-circular arc, and after the valve is opened, it is a full flow channel.

No valve cavity structure, the medium will not accumulate.

The flow channel and sealing surface are made of vulcanized wear-resistant rubber, which has better wear resistance and erosion resistance.

If our knife valve cannot meet your choice, we can provide you with special made.

Chief Features

Face to face dimensions adopt short series, and light weight valve is adopted, so as to save pipe supporter.

The valve body provides a continuous flow direction, which means that in the open position, it will not produce cavities, so it will not fluctuate in the medium, and the load loss is minimal.

Full bore design provides flow rate with low pressure drop.

The internal design will not accumulate solids in the seat area.

The valve seat is composed of two rubber ferrules symmetrically located on both sides of the valve body. The material is natural rubber, and there is a metal core inside to help keep the shape from deformation. The elasticity of the ferrule ensures that they are permanently connected to prevent solid accumulation between the two parts of the valve body.

This valve is designed for wear-resistant cut-off, and the ferrule protects the valve body.

For maintenance, the ferrule can be replaced and taken out from the outside of the valve body, making the operation easier.

The standard packing is composed of a specially designed EPDM “V” ring, which provides the overall water seal between the body disc to prevent various kinds of leakage. It also has a grease packing strip to help the operation of the open and close. They can be replaced at an easily accessible position without dismantling the valve on the pipeline.

The valve with a scraper to clean the valve disc, to prevent the surface of the disc from caking and reduce the switching resistance.

The design of easy to replace consumable parts enables the PU lined and disc to be replaced on site, which is efficient and energy-saving

Points

Polyurethane is a kind of polymer containing urethane type repeating structural unit in the macromolecular chain.

It has super wear resistance. In the immersion state, the wear resistance is 8 times that of cemented carbide steel, 7 times that of vulcanized rubber, and 3 times that of ultrahigh molecular polyethylene.
