Metal Seated Wafer Butterfly Valve with Motorized Actuator, 0-10, 1-5 VDC / 4-20mA
This metal seated butterfly valve motorized actuator is composed by motorized butterfly valve actuator and wafer type butterfly valve. Butterfly motorized valve is widely used on industrial pipes with medium temperature ≤ 425 °C for regulating flow and shutting off the fluids.
The difference between electric soft seated butterfly valve and metal seated butterfly motorized valve:
1. The soft sealted butterfly valve is used in low pressure and normal pressure places, and the metal seated butterfly motorized valve can be used in medium and high pressure working conditions.
2. The electric soft seated butterfly valve is applied for low temperature and normal temperature environment,and metal seated butterfly valve with motorized actuator can be used in low temperature,normal temperature,high temperature and other environments.
3. The former is mostly a mid-line structure,and the latter is generally a single eccentric,double eccentric and three eccentric butterfly valve structure.
4. The soft seated butterfly valve has better sealing performance than the triple eccentric metal seated butterfly valve, but the three eccentric metal seated butterfly motorized valve can maintain a good seal under high pressure and high temperature environment.

The Features of Metal Seated Wafer Butterfly Valve with Motorized Actuator:
1. The butterfly valve electric adopts a three-eccentric sealing structure, and the valve seat and the butterfly plate have almost no wear, and have a tighter and tighter sealing function.
2. The sealing ring is made of stainless steel. It has the double advantages of hard metal sealing and elastic sealing. Metal seated butterfly motorized valve has excellent sealing performance in both low temperature and high temperature conditions, and has corrosion resistance and long service life.
3. The sealing surface of the disc plate is made of surfacing cobalt-based hard alloy. The sealing surface is resistant to wear, high strength, large flow area, small flow resistance and long service life.
4. The butterfly valve motorized actuator has a two-way sealing function. It is not restricted by the flow direction of the medium during installation, and is not affected by the spatial position.
5. The protection device of butterfly valve motorized actuator has double limit, overheat protection and overload protection. The total travel time is 15 seconds, 30 seconds, 45 seconds, 60 seconds. This metal seated butterfly motorized valve is with manual device.
