Fully automatic Siemens electric butterfly valve

Fully automatic Siemens electric butterfly valveValves with metal seals generally have a longer lifespan than those with elastic seals, but it is difficult to achieve * sealing. Metal seals can adapt to higher operating temperatures, while elastic seals have the drawback of being limited by temperature. The structure is simple, the volume is small, and the weight is light, consisting of only a few parts. And it can be quickly opened and closed by simply rotating 90 °, with simple operation, and the valve has good fluid control characteristics. When the electric butterfly valve is in the * open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body, so the pressure drop generated by this valve is very small, which has good flow control characteristics. Electric butterfly valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate.

Fully automatic Siemens electric butterfly valvePerformance advantages:

1. Adopting a double eccentric structure, it has a sealing function that becomes tighter as it is closed, and the sealing performance is reliable.

2. The sealing auxiliary material is paired with stainless steel and nitrile oil resistant rubber, which has a long service life.

3. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media, with a user's choice.

4. The butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance.

5. The overall baking paint can effectively prevent rust and can be used in different media as long as the valve seat sealing material is better sealed.

Structural features:

1. Under high temperature and high pressure conditions, it still has stable sealing performance Its special sealing system ensures high sealing performance in various temperature ranges from ultra-low temperature to ultra-high temperature

2. The three-dimensional eccentric sealing system, combined with human optimized design, reduces the resistance to valve opening The sealing surface of the butterfly plate is a conical shape that protrudes upwards. When opened, all points on the circumference of the butterfly plate simultaneously detach from the sealing ring, making it difficult for solid objects to accumulate on the sealing surface The valve closing process is completed by the elastic compression of the sealing ring.

3. There is no jamming phenomenon between the butterfly plate and the sealing ring.

4. The sealing performance of the valve is not affected by temperature changes.

5. The valve stem diameter seal adopts graphite compression formed sealing ring In summary, zero leakage is ensured, and the metal seal, combined with zero leakage before, during, and after a fire, makes it an intrinsic fire safety type.
