Overview 

 I plant the introduction of foreign advanced technology to produce gate valve, the main material is stainless steel or carbon steel spray paint, soft rubber seal, with a light weight, flexible operation, anti-corrosion, no rust, easy installation and maintenance, reliable sealing and other functions, can be widely used for water treatment plants, water plants, irrigation, environmental protection, power, ponds, rivers and other projects, as the cut-off, adjust the water flow and control purposes. Valve based on using the occasion can be divided into: 1, [channel gate] for the channel, and will be closure, is normally used for three to seal; 2, [the system water valve] is used as a channel on or off the import and export , generally used for four-way seal, 3, [regulation valve] is not used to regulate the large flow; 4, [weir gate] is used to adjust the water level. 

 Features 

 Light weight: about cast iron gate 1 / 3 
 Corrosion resistance: acid and most corrosive chemicals and sewage, seawater; 
 Sealing: a rubber to metal seal, sealing gasket for the hollow structure, good sealing performance; 
 Small torque: the door, light weight, the friction between the door and the slide resistance, it makes the hand wheel torque is not more than 100N; 
 Unique structure: the temperature and rigidity and reliable welding structure, high performance seals to ensure the effective opening and closing the gate, the unique wedge design allows the gate closed and open and close more reliable, and can be more negative level; 
 Long life: between the door and the slide only to the last short contact sealed, the sealing surface friction loss is very small, stainless steel gates life of up to 15 years, more than 10 years service life of carbon steel gate; 
 Easy maintenance: wedge-shaped blocks can be adjusted, after years of use, such as a partial leakage, simply adjust the wedge to increase the sealing gasket compression, time-saving, low maintenance cost; 
 Hoist: the situation may be different selection of manual, pneumatic, electric, hydraulic power, hydraulic; 
 Easy installation: the gate frame fixed by the second Concrete pouring, and convenient.
