Electric intelligent flange cast steel butterfly valve

1 d943h-16c dn250Electric intelligent flange cast steel butterfly valvesummary:

Electric flange type regulating butterfly valve，The butterfly valve actuator is matched with an input control signal (4~20mADC or 1~5VDC) and a single-phase power supply to control operation. It has strong functionality, small size, lightweight and pleasant, reliable performance, simple matching, and large flow capacity, especially suitable for occasions where the medium is viscous, contains particles, or fibrous. At present, this valve is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and power.

二、 d943h-16c dn250Electric intelligent flange cast steel butterfly valveExecuting Agency:

1. Powerful functions: intelligent, adjustable, switch type.
2. Compact size: The volume is only about 35% of similar products.
3. Easy to use: using single-phase power supply, simple wiring; Adopting a spherical protruding structure with * makes observation more convenient; No refueling, no inspection, waterproof and rust proof, and can be installed at any angle.
4. The protective device has dual limit, overheat protection, and overload protection. The full travel time is 15 seconds, 30 seconds, 45 seconds, and 60 seconds. And with manual function.
5. Intelligent CNC: The built-in module adopts advanced computer single-chip and intelligent control software to directly receive standard signals (4-20mA DC/1-5VDC) output from computers or industrial instruments to achieve intelligent control and precise positioning of valve opening.

IIIMain technical parameters:

1. Valve body form: Straight through cast valve with nominal diameter of DN50-1200mm and nominal pressure of PN1.0, 1.6, 2.5MPa. Flange standards GB/T9113, JB/T79, HG20594 and other standard connection forms: flange type, clamp type valve cover form, integrated gland type, pressure plate compression type sealing packing, V-shaped polytetrafluoroethylene packing, impregnated polytetrafluoroethylene packing, asbestos braided packing, flexible graphite

2. The valve core form of the valve is a butterfly shaped vertical plate with approximately equal percentage of flow characteristics. The valve core material is cast steel or stainless steel (CF8, CF8M, CF3, CF3M)

3. Main technical parameters of electric actuator models CHR, 3810R, DZW, HQ, PSQ. Power supply voltage: 220V/50Hz, 380V/50Hz, input signal: 4-20mA or 1-5V · DC, output signal: 4-20mA · DC. Protection level: equivalent to IP65 (or IP67). Explosion proof mark: Exd Ⅱ BT4. Manual operation function: handle. Environmental temperature: -25~+70 ℃, environmental humidity: ≤ 95%

4、 Installation and maintenance:

1. During installation, the valve disc should be stopped in the closed position.

2. The opening position should be determined according to the rotation angle of the butterfly plate.

3. Butterfly valves with bypass valves should be opened before opening.

4. The installation should be carried out according to the manufacturer's installation instructions. For heavy butterfly valves, a solid foundation should be set up.
