Electric actuator Driven Ductile iron Wafer Type concentric
Butterfly Valve
Product introduction:
Concentric butterfly valve normally with soft seal is the preferred
conventional butterfly valve for pipeline, it can be operated with
various type of actuators, according to user's requirements, either
in manual, electric, pneumatic, or other forms. Different materials
raw material of body, disc, seat can be provided. The valve is
applicable to different media and working conditions and makes the
cost and performance to achieve the best match.
The soft seal butterfly valve is suitable for the temperature lower
than 120℃ and nominal pressure lower than 1.6 MPa,and it is
suitable for the industries such as water supply and drainage,
sewage, food, heating, gas, shipping, hydro-power, metallurgy,
energy system, and textile,particularly suitable for two-way seal
box valve bodies that are easy to be rusted.
The electric butterfly valve matched with electric actuator, can be
ON/OFF function or adjusting function, intelligent type electric
actuator with input control signal (4-20mA or 1-5VDC) and
single-phase power supply to control operation,has strong
function,small volume,light and pleasant,reliable
performance,simple matching,large flow capacity, At present,the
electric butterfly valve product is widely used in
food,environmental protection, light industry, petroleum, paper,
chemical,teaching and research equipment,power and other industries
in the industrial automatic control system.

Product features:
1. The electric butterfly valve body only requires the smallest
installation space, and the working principle is easy and reliable.
2. Electric butterfly valves have great flow performance and
minimal pressure loss when passing through the valve.
3. Electric butterfly valves have significant economic benefits,
especially for larger diameter butterfly valves.
4. The valve body of the electric butterfly valve is matched with a
standard raised pipe flange.
5. Electric butterfly valves have approximately equal percentage
flow characteristics and can be used for regulation or switch
control.
6. The electric butterfly valve adopts a special seat seal suitable
for clean liquids and gases.
