Hard sealed electric cast steel butterfly valve

1 d943y-25c dn200Hard sealed electric cast steel butterfly valveProduct Introduction:

Electric flange hard seal butterfly valveWidely used in industries such as petroleum, chemical, food, medicine, textile, paper, etc., it can be installed on industrial pipelines with temperatures ≤ 425 ℃ and media such as gas, air, steam, etc. for regulating flow and cutting off media. Equipped with electric execution, it can achieve remote control and automated operation. The electric triple eccentric butterfly valve and electric metal sealed butterfly valve series products are long-lasting and energy-saving butterfly valves.

二、 d943y-25c dn200Hard sealed electric cast steel 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.

3、 Main technical indicators:

Control accuracy: 0.1% -3.0% (adjustable through U4 parameter)
Can receive feedback signals from electric actuators: potentiometer 500 Ω -10K Ω
Can receive external control signals (DC): 4-20mA (1-5V, 0-10V, switch quantity, etc. customized before leaving the factory)
Input impedance: 250 Ω;
By modifying the U1 parameter, the following modes can be set: ① DRTA/forward action, RVSA/reverse action mode ② "Interrupt" mode when the input signal is interrupted - OPEN, STOP, SHUT
Optional: ① Controllable silicon output (AC, 600V, 25A) ② Relay output (AC, 250V, 10A) ◆ Indicate when ordering
