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.

 

Product Benefits

Erosion-Resistant Rubber Lining: The flow channel features a vulcanized wear-resistant rubber lining, maximizing resistance against abrasive media.

Bi-Directional Zero Leakage Sealing: Uses an inlaid U-shaped sealing strip structure to achieve absolute bubble-tight isolation from both directions.

No Medium Accumulation: A smooth gate bottom and cavity-free design prevent thick slurry and impurities from accumulating.

Strong Mechanical Shear Force: Equipped with a sharp cutting tool designed to shear easily through viscous, heavy, or abrasive media.

Lightweight Wafer Body: The compact, ultra-thin two-piece body style uses a short structure length to minimize overall pipeline weight.

Multi-Actuator Configuration: Supports versatile operational mechanisms including manual handwheel, worm gear, electric, or pneumatic systems.

FAQs

1. What applications suit a rubber lined knife gate valve?

A rubber lined knife gate valve handles viscous, heavy, or abrasive media like coal slurry, ore slurry, and ballast slurry in mining and coal-fired power plants.

2. How does a slurry knife gate valve prevent media accumulation?

This slurry knife gate valve features a smooth gate bottom without grooves and lacks an internal valve cavity, ensuring medium and impurities do not accumulate inside.

3. What manufacturing capabilities does your China knife gate valve factory offer?

As a leading China knife gate valve factory, we feature dedicated workshops and superior mold casting capabilities to deliver compact, lightweight, and ultra-thin two-piece valve bodies.

4. Why do global buyers trust LIXIN among knife gate valve manufacturers?

LIXIN stands out among knife gate valve manufacturers by providing bi-directional zero-leakage sealing, customized material options, and flexible manual, electric, or pneumatic operations. To find out more about leading industry options, check the top knife gate valve manufacturers.

5. What materials do slurry knife gate valve manufacturers use for discs?

Professional slurry knife gate valve manufacturers utilize high-strength metals for discs, including stainless steel and duplex steel, to withstand strong shear forces against abrasive fluids.

6. How does the knife gate valve achieve zero leakage?

The knife gate valve utilizes a U-shaped inlaid sealing strip and side sealing structure, achieving bi-directional soft seat zero leakage on three sides.

7. Can this slurry knife gate valve handle power station ash removal?

Yes, the sharp cutting tool provides strong shear force, making the slurry knife gate valve ideal for power station ash removal and bottom ash isolation.

8. What pressure ratings are supported for this knife gate valve?

This bi-directional knife gate valve safely manages industrial pressure ratings, specifically tested for 1.0Mpa, 1.6Mpa, and 150LB system requirements.

9. What operation methods do knife gate valve manufacturers configure?

To satisfy diverse automation needs, knife gate valve manufacturers equip units with handwheel, worm gear, electric, or pneumatic actuation systems.

10. Should I choose a knife gate valve or a butterfly valve for slurries?

For thick media like limestone slurry, a slurry knife gate valve outperforms due to its groove-free design and sharp cutting tool. To evaluate technical differences, read knife gate valves vs butterfly valves: which is better.
