FN1-BV1W-1E (Wafer Butterfly Valve–Electric actuator)
The opening and closing part of butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting.
1. The valve adopts a new structure, which has the sealing function of closing more tightly and has good sealing performance.
2. Stainless steel and NBR oil resistant rubber are used as sealing materials, which are long in use.
3. The rubber seal ring can be located on the valve body or butterfly plate. It can be used in different media for users to choose.
General Use: Water,seawater,gas, pressurized air, acids etc.
