 Extensions are electric knife gate valve Product Overview: 

 The extension rod type knife gate valve is the valve of a strong Germany in actively absorb the advanced technology on the basis of the development of a new knife gate valve, using the stem extension, applicable in underground and other special conditions. Stem length can be tailored to customer requirements. Drive part of the multi-turn electric actuator to drive and control the valve opening and closing, and operating personnel in the control room remote valve control can be field manual operation, you can also achieve automatic computer control with computer. Lengthened stem knife gate valve actuator can be equipped with manual, electric, pneumatic, hydraulic, etc., to open and close the valve. 

 Electric knife gate valve extension rod electric knife gate valve main purposes: 

 For mine plant preparation, slagging, urban sewage treatment, food, paper, pharmaceutical, oil, chemical oil, water, steam pipes on the road, water, mud, connect or disconnect the line of gold powder , ores, slag, slime, pulp, wood pulp, tailings, fibers, dust, chemicals, sewage treatment, sedimentation tanks, asphalt, silos, export, fruits, grains, slaughter plant wastewater and other media. 

 The plus pole electric knife gate cut off the media function: 

 The name suggests is the bottom of the flat valve plate of the knife gate valve has a knife oblique incision, cut off the media function, making the valve is closed from the medium blocked. This valve is generally used to hoist the circulation of the pulp, coal ash, chemical raw materials, sewage, food and other media. The pressure range is generally 1.6MPa or less, the temperature is below 120 ℃, high temperature can also be used instead of using special materials. Sealing performance requirements can be divided into flexible seal and hard seal. The soft seal can reach leaks, hard seal according to the different leak rank test. The valves are easy to operate, open free, flexible and reliable movement; the valve assembly and maintenance is simple and reasonable structure, sealing, seals replacement is convenient and practical.
