Overview

Danfoss electric butterfly valve is easy to open and close quickly, labor-saving, with low fluid resistance, and can be operated frequently; The installation should be carried out according to the manufacturer's installation instructions. For heavy butterfly valves, a solid foundation should be set up.

Product Details

Danfoss electric butterfly valveFunction: Implement the on/off of pipeline media and control the flow rate of media.

Application areas: urban water supply and industrial, agricultural water transmission pipelines, etc.

Simple structure, easy operation, simple installation, good sealing performance, long service life, high reliability, and good interchangeability of parts

Valve plate materials available: ductile iron, aluminum bronze, stainless steel, PFA PTFE coated stainless steel valve plate Hastelloy, bi-directional stainless steel.

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,

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

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

5. The valve stem shaft 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 inherently fire safe type

Danfoss electric butterfly valveElectric butterfly valves are suitable for situations that require flow regulation. Due to the significant pressure loss of butterfly valves in pipelines, which is about three times that of gate valves, when selecting butterfly valves, the impact of pressure loss on the pipeline system should be fully considered, as well as the robustness of the butterfly plate to withstand the pressure of the pipeline medium when closed. In addition, it is necessary to consider the limitations of the working temperature that the elastic valve seat material can withstand at high temperatures. The structural length and overall height of butterfly valves are relatively small, with fast opening and closing speeds and good fluid control characteristics. The structural principle of butterfly valves is suitable for making large-diameter valves. When a butterfly valve is required for controlling flow, it is important to choose the correct size and type of butterfly valve so that it can work properly and effectively.
