Product Description

DT943H electric elastic metal seal butterfly valve overview

DT943H electric elastic metal seal butterfly valve adopts a "U" type stainless steel seal ring, the precision elastic seal ring with the polished butterfly plate three-dimensional eccentric contact. It solves the problem that the sealing surface of the traditional eccentric butterfly valve is still in the sliding contact friction when opening and closing 0° ~ 10°, and realizes the effect that the sealing surface is separated when the butterfly plate is opened, and the contact is sealed when the contact is closed, so as to extend the service life and achieve the purpose of good sealing performance. Therefore, it is widely used in the medium temperature ≤550ºC metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage and other corrosive media pipelines, is the best device to adjust the flow and cut off the fluid. DT943H electric elastic metal seal butterfly valve characteristics 1, the butterfly valve structure is simple, compact, light weight, easy to install and disassemble, convenient maintenance; 2, the butterfly valve adopts stainless steel "U" type sealing ring, has a certain elasticity no matter in the case of high temperature, low temperature, it and the butterfly plate have excellent sealing; 3, the butterfly valve's three-dimensional eccentricity, after strict calculation, "U" type sealing ring and butterfly plate almost no friction, long service life, and has the function of the tighter close; 4, the sealing surface of the butterfly plate adopts surfacing welding cobalt-based cemented carbide, the sealing surface is wear-resistant, long service life; 5, the butterfly valve structure is unique, "switch" only need to turn the stem 90° to complete. The operation is flexible, convenient, labor-saving, not affected by the medium pressure, reliable sealing performance; High temperature resistance, low temperature resistance, corrosion resistance.

Three, DT943H electric elastic metal seal butterfly valve actuator

CH series features:
1. Powerful function: intelligent, regulating, switching type.
2. Compact size: the volume is only equivalent to about 35% of similar products.
3. Easy to use: single-phase power supply, simple wiring; The original spherical protruding structure is adopted to make observation more convenient; No refueling, no spot inspection, waterproof and rust-proof, arbitrary Angle installation.
4. The protection device has double limit, overheat protection and overload protection. The full travel time is 15 seconds, 30 seconds, 45 seconds, 60 seconds. And with manual function.
5. Intelligent numerical control: The built-in module adopts advanced computer single chip and intelligent control software to directly receive the standard signal (4-20mA DC /1-5VDC) output of the computer or industrial instrument to achieve intelligent control and accurate positioning of the valve opening.
3810 series or NA series electronic angular travel actuator can also be selected. PSQ series or DYR series can also be selected. ≥DN200 caliber valves generally use 380VAC electric actuators. Domestic brands such as Ruiji, Aotok, Yangzhou Electric Power, Tianertong, Lanling, etc.; Foreign brands are Britain Rotok, France Bernard, Germany Ouma, Germany Xibosi (Siemens) and so on.
