Coal Chemical sewage electric knife gate valve flange PX943W-16C

Coal Chemical sewage electric knife gate valve flange PX943W-16C flat bottom valve plate having Profile knife oblique incision, has cut off media features that make the valve is closed from the media block. This valve is generally used for opening and closing the flow of pulp, ash, chemicals, sewage, food and other media. The pressure is generally within the range of 1.6MPa use, the temperature at 120 ℃ the following general use, high temperatures can also be used instead of using special materials. The sealing performance requirements can be divided into soft seal and hard seal. Soft seal leakage can reach 0, hard seal test easy operation Depending on the valve leakage levels, open free, flexible and reliable motion; valve assembly and maintenance is simple, reasonable seal structure, convenient and practical seal replacement. Coal Chemical sewage electric knife gate valve flange PX943W-16C Features ◎ open and close rapidly, balanced and reliable, high degree of automation. ◎ installation height and location unrestricted. ◎ explosion-proof electric apparatus in explosive, toxic atmosphere can even work properly. ◎ with a manual, if power supply interruption, may be manually operated to open or close the valve, effective control of the media, to prevent accidents.
