Uses and Features D941X electric soft sealing flange sealing butterfly valve is made of rubber and carbon steel or stainless steel valve plate, stem composition. For temperature ≤120 ℃ such as textile, paper, food, pharmaceutical, chemical, oil, electricity, water supply and drainage, etc., the role of the media flow and the closure of the gas pipeline to make adjustments. Its main features are: 1, novel design, reasonable, unique structure, light weight, open and close quickly. 2, the operation torque is small, easy to operate, energy smart. 3, can be installed in any position, and easy maintenance. 4, the seal can be replaced, reliable sealing performance bi-directional sealing reach zero leakage. 5, sealing material aging, corrosion resistance and long service life. Standard design standards: GB / T2238-1989 flange dimensions: GB / T9113.1-2000; GB / T9115.1-2000; JB79 length of the structure: GB / T12221-1989 pressure test: GB / T13927-1992; JB / T9092-1999 Actuator 1. Power: 220V, 380V (special order 660V, 440V), 50Hz (special order 60Hz); control line voltage 220V / 50Hz (special order 60Hz); remote control voltage 24VDC. 2. Ambient temperature: -20- + 60 ℃ (special order -60- + 80 ℃) 3 relative temperature:.. ≤90% (25 ℃ when) 4 common type and outdoor type for non-flammable / explosive and non-corrosive media sites; explosion-proof products have dⅠ and dⅡBT4 two kinds, dⅠ for coal mining face non; dⅡBT4 used in factories, for environmental as ⅡA, explosive gas mixtures ⅡB stage T1-T4 group. (See GB3836.1) 5 Degree of protection: for outdoor and explosion-proof IP55 (can be customized IP67). 6. Operating system: for a short time 10 minutes (30 minutes can be customized). ? 3810 series can also be used or NA series of electronic rotary actuators. May choose PSQ series or DYR series. ≥DN200 diameter valves generally use 380VAC electric actuators.
