Knife Gate Valve For Power Plant
These knife valves are used in pipelines system in power plants to cut off and connect pipeline media. They are very insect-bite pipeline control components. Valves used in power plants are often in high temperature and high-pressure media. Our valves use a unique self-sealing design. The higher the pressure, the more reliable the seal. Due to the special performance, technical characteristics, and working conditions, these gate valves are irreplaceable products.
Slurry Valve For Mining
The slurry valve commonly used in mining, power plants, etc slurry application. The knife gate valve has the advantage of being very compact due to the linear movement of the closing flap (the plate that prevents fluid flow in the closed position). The knife gate valve is primarily a shut-off valve, although it can also be used as a control valve when the valve is in a partially open position.
Knife gate valves can be used for fluids containing solid particles, such as wastewater or sludge. Generally, the knife gate valve is designed to be sealed on the upstream side of the circuit (fluid inlet side), but some valves are sealed on both sides, so the knife gate valve can be used regardless of the fluid flow direction. In the open position, since the valve does not cause a change in the direction of the fluid, the head loss is very low. However, the closing and opening times can be very long, and regular maintenance is required to correct the wear between the valve and the seal.
Slide Gate Valve For Sewage
In the application of sewage or water treatment, there are several reasons to use stainless steel as a key component to ensuring the long-term reliable function of the valve. Every time the valve is opened, the knife gate itself will be scraped back and forth by two scrapers on both sides. These scrapers reduce unnecessary valve maintenance work, thereby saving time and money.
An important issue in wastewater applications is corrosion. The knife gate valve made of stainless steel makes the valve less likely to be damaged due to medium corrosion, so it requires less maintenance or replacement. Corrosion not only causes frequent maintenance, but may also cause permanent failure of the valve because it prevents the valve from closing properly.
Knife Gate Valve For Pulping
The slurry valve is used for slurry pipelines. The valve seat is made of ceramic, PU, rubber or tungsten carbide and is in contact with the edge of the gate. The valve can be pressurized in both directions. There is no groove at the bottom to prevent the valve from blocking slag. This type of valve is generally used in clean water, sewage, and Used in liquid media. The knife gate valve, as the name implies, is a gate with a knife-edge. When the valve is closed, it can cut off the slag in the medium. The gate can be easily closed without blocking. This kind of valve is generally used for mining, processing plant, cyclone, etc, as well as other solid media.
Knife Gate Valve For Powder
The advantage of this valve is that there is no groove in the diameter, the medium will not be blocked and blocked, and it has the characteristics of full-diameter flow, which is suitable for use in pipelines with powder and granular media. The sealing structure can be divided into soft sealing and hard sealing structure. The penetrating knife gate valve has the characteristics of precise structure, good manufacturability and compact structure. The sealing valve seat is designed with a movable structure, which has the functions of anti-wear and automatic compensation, so it has a longer life. In the process of closing and opening, the valve seat and the gate keep moving closely, which makes the opening and closing force of the valve stable and has the characteristics of cutting off the medium. Configure the handwheel to directly operate the handwheel to open and close the valve.
Knife Valve For Medium and High Pressure
The high-pressure knife gate valve has excellent flow characteristics, and the penetrating valve plate design ensures reliable sealing; at the same time, the series of valves are available in different materials
