Stainless steel electric three eccentric butterfly valve, electric three eccentric butterfly valve, three eccentric butterfly valve

Stainless steel electric three eccentric butterfly valve, controlled by electric actuator, can be adjustable type electric, can also be switch type electric. Nominal pressure: 1.0MPa-6.4MPa, nominal diameter: DN50-DN2000. Because the valve body and valve plate and other parts are made of stainless steel, so it can be applied to a variety of corrosion media, the temperature is less than 570℃. Stainless steel material: 904L, 254SMo, 1.4529 super stainless steel, 2205, 2507 duplex steel, 317L, SS304, SS316, SS316L stainless steel. The design structure of the three eccentric butterfly valve is designed according to the principle of three-dimensional eccentricity, the butterfly plate is provided with multilayer soft and hard material superposition of the sealing ring, the valve plate sealing ring and the valve seat contact surface is oblique taper, the contact Angle produces a slight "wedge effect", so that the sealing ring occurs soft and radial compression, the sealing is more reliable, and not easy to close too much.

Parameters of the electric actuator

Stainless steel electric three eccentric butterfly valve electric has Z type multi-rotary electric, and Q type partial rotary electric, control mode: switch, analog, bus system, bus + conventional, frequency conversion speed regulation. Electric brands can be selected: German Aoma, British Rotoke, the United States Wartec, Yangzhou Electric Power, Siemens, Lanling, Tiantong, etc.

The performance of the electric actuator conforms to the provisions of JB/T8528-1997 (technical conditions for common valve electric devices). The performance of the flameproof type conforms to the provisions of GB3836.1-2000 (Electrical equipment for explosive gas environments: general requirements), GB3836.2-2000 (electrical equipment for explosive gas environments: Part 2: flameproof type "d") and JB/T8529-1997 (technical conditions for flameproof electrical devices).

Stainless steel electric three eccentric butterfly valve is widely used in many industrial fields because of its high sealing, long life and precise adjustment ability. The following are the main application fields: Power industry: in the boiler water supply, steam pipeline and desulfurization system of thermal power plants, withstand high temperature and high pressure conditions to ensure the stable operation of the system. Chemical industry: used to deal with strong corrosive media, such as sulfuric acid, hydrochloric acid, etc., through fluorine or Hastelloy alloy material to achieve chemical inertness, ensure production safety. Natural gas industry: in liquefied natural gas (LNG) transmission, the sealing performance at low temperature is maintained, and the electric regulation function can accurately control the flow rate, reduce the pressure loss of the pipeline, and realize energy saving. Water treatment and environmental protection industry: used in sewage treatment plant pipeline switching, sedimentation tank sludge discharge and other scenarios, suitable for sewage, sludge and other media. Food and sterile production line: Used for material handling and CIP cleaning system to ensure a hygienic and sterile environment. Metallurgy and BUILDING materials industry: It is used as a gas medium to regulate the flow or cut off device in the dustcontaining cold or hot air gas pipeline of ventilation and environmental protection engineering
