IIDN300 electric butterfly valveProduct Features:
1. This valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter as viewed.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperatures, corrosion resistance, and long service life.
3. The sealing surface of the disc plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life
4. The large-sized butterfly plate adopts a frame structure with high strength, large overcurrent area, and low flow resistance.
5. This valve has a bidirectional sealing function, which is not limited by the flow direction of the medium or the spatial position during installation, and can be installed in any direction.
6. The drive device can be installed in multiple stations (rotated 90 ° or 180 °) for easy user use.

Electric explosion-proof butterfly valve, with a protection level of ExDII BT4, is widely used in pipelines with explosive gases or coal mine bottom mining faces. It has stable quality and good explosion-proof performance. Our company can produce explosion-proof voltages of three-phase 660V, 380V, and two-phase 220V. The appearance and quality of the product have been repeatedly praised by users! In addition to the regular switch type, the product can also have an integrated explosion-proof type and an intelligent integrated explosion-proof type to meet more practical requirements. D9B4 (7) 1F/D9B4 (7) H series electric explosion-proof butterfly valve can be used to meet the needs of different control coefficients and working environments. The performance of this product meets the requirements of JB/T8528-1997 "Technical Conditions for Electric Devices of Ordinary Valves". The performance of the explosion-proof type complies with the provisions of GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements" GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d "" and JB/T8529-1997 "Technical Conditions for Explosion proof Valve Electric Devices". There are two types of explosion-proof products, dI and dIIBT4. dI is suitable for non mining working faces in coal mines; DIIBT4 is used in factories and is suitable for explosive gas mixtures in environments of IIA and IIB levels T1 to T4. (See GB3836.1 for details). Explosion proof type is IP55 (special order IP67) working system: short-term 10 minutes (special order 30 minutes). Power supply: motor is three-phase AC, 380V (special order 660V or 220V), 50Hz (special order 60Hz); The control line is 220V, 50Hz (special order 60Hz); Remote control is 24VDC
