Manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electro-hydraulic and pneumatic drive and other driving methods. Knife gate valve shape: bright rod, dark rod two. Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, such as fluorine lining. Knife gate valve seal: hard seal, soft seal, single seal, double seal and other material seal.
Slim knife gate valve with its small size, small flow resistance, light weight, easy installation, easy removal and other advantages of the complete settlement of the ordinary gate valve, ball valve, globe valve, globe valve, butterfly valve and other types of valve flow resistance , Heavy weight, difficult installation, large area and other difficult problems. After the knife gate valve appears, a large number of general-purpose cut-off valves and regulating valves have been replaced. Today, the world's largest amount of knife gate valve is the United States and Japan.
Product Performance
1. Valve control can be done locally and remote control, but also in accordance with the requirements of users to achieve remote location display and remote control.
2. Light weight: The body is made of carbon steel, weight loss of about 20% -30% than the traditional gate valve, easy installation and maintenance.
3. The use of the valve can improve the closure of the pipeline sealing performance, minimize leakage, to improve production efficiency and protect the environment will play a positive role in promoting.
4. Sealing surface using high wear-resistant, corrosion-resistant ceramic materials, the use of mosaic technology, high corrosion resistance, good wear resistance, which makes the valve life is long, the price of ordinary valve to enhance 10 times.

Features
1, improved gate seal surface, the surface can be scraped sticky adhesive, automatic cleaning debris.
2, stainless steel gate to prevent leakage caused by corrosion seal.
3, hard gold seal face to ensure sealing wear resistance and requirements.
4, the valve body sealing surface no groove, does not produce accretion, can guarantee open and flexible.
5, short structure length, can save raw materials, installation space also effectively support the pipe strength.
6, science on the packing seal design, so that the seal is safe and effective, durable.
7, triangular bracket to save raw materials, to ensure the mechanical properties needed.
8, the guide block on the valve body to make the correct gate movement, four squeeze blocks to ensure effective gate seal.
9, Body stiffener design to improve the strength of the body.
10, stainless steel stem durable, studs to hoist more quickly.
11, optional drive mechanism.
More than 12,150 caliber, fully enclosed structure, more effective and prevent leakage.
13, Viton sealing surface to achieve sealing effect, improve the use of temperature.
14, the rubber sealing surface directly vulcanized in the valve body, will not fall off.

Installation and use instructions
1. Knife gate valve before installation must check the valve cavity and sealing surface and other parts, do not allow dirt or grit attached;
2. The bolts of connecting parts, require uniform tightening;
3. Check the packing parts require compression, both to ensure the packing seal, but also to ensure that the gate open flexible;
4. Before installing the valve, the user must check the valve model, connection size and attention to the flow of the medium to ensure consistency with the requirements of the valve.
5. When installing the valve, users must reserve the necessary space for valve actuation;
6. Drive wiring according to the wiring diagram;
7. Knife valve must be regularly maintained, shall not be free to crash and squeeze, so as not to affect the seal.
Use and maintenance
1, hand wheel, handle and transmission are not allowed to start lifting, and no collision.
2, double gate valve should be mounted vertically (ie stem in a vertical position, the hand wheel at the top).
3, with bypass valve gate valve should be opened before opening the bypass valve (to balance the pressure difference between import and export and reduce the opening force).
4, with the gear valve, according to the instructions of the product installation instructions.
5, if the valve is often used switch, lubrication at least once a month.
