Electric metal to metal butterfly valves are widely used in metallurgy, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines where the medium temperature is ≤425°C to adjust flow and cut-off fluid. During the national holiday period, the NSEN workshop complete a batch of on-off electric bi-directional sealing metal butterfly valves. This batch of electric butterfly valves can realize remote control and lcoal operation.

  ● The connecting bracket implements the ISO5211 standard and can be connected with various electric, pneumatic, hydraulic, manual and other driving devices

  ● There is a certain distance between the top of the top flange and the operating actuator, which helps protect the actuator from over heat

When the electric is delivered, the stroke of the control mechanism has been adjusted. In order to prevent the power from being connected in the wrong direction, the user must manually open the valve plate 30 degrees before turning on the power for the first time, and check the direction of the indicator plate and the opening direction of the valve. Is it consistent? Then restore the manual to electric, follow the instructions, wiring diagram, control principle diagram, and confirm the correct wiring, and then open/close the valve through the button on the control box. If the power cord is connected reversely, it will cause the travel switch to fail and damage the worm gear and electrical equipment.

When the electric butterfly valve is in use, if it fails, stop using it immediately and find out the cause

Features of electric hard seal butterfly valve:

The design of the triple eccentricity principle makes the space movement trajectory of the sealing surface idealized. There is no friction and interference between the sealing surfaces. In addition, the sealing material is selected appropriately, so that the butterfly valve has the sealing performance, corrosion resistance, high temperature resistance and resistance. The grindability has been reliably guaranteed. Its main features are as follows:

1. Small operating torque, convenient operation, labor-saving and smart;

2. The three-dimensional eccentric structure makes the butterfly disc tighter and tighter, and its sealing performance is reliable, achieving zero leakage;

3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
