2. What is function of butterfly valve?
A: Butterfly valve is also called ON-OFF valve, it is used for flow control: start and stop the fluid.
3. What is working principle of double eccentric butterfly valve?
A: When the sealing surface is closed, friction occurs between the disc and the valve seat, and the sealing effect is very good. It has the characteristics of small area and strong pressure. After the valve is opened, the butterfly plate can quickly separate from the valve seat, which greatly eliminates unnecessary excessive extrusion and scratching between the butterfly plate and the valve seat, reduces the opening resistance, reduces wear, and increases the service life of the valve seat.
4. What is working principle of triple eccentric butterfly valve?
A: Due to the effect of the eccentric shaft, when it is close completely, the butterfly plate moves a certain distance into the sealing cone surface of the valve seat, and the sealing surface of the butterfly plate and the valve seat matches to achieve reliable sealing performance. It makes up for the contradiction that hard seals which also named metal to metal seal have poor sealing, while soft seals have good sealing effects but are not resistant to high temperatures.
5. What is the connection method of the offset butterfly valve?
A: All wafer, double flange, and lug end are suitable for the eccentric bfv valve.
6. What is the actuator of the eccentric butterfly valve?
A: Worm Gear, Electric, and Pneumatic can be selectable.
7. Can you casting our Logo on the Valve body?
A: Yes, we provide OEM service, you can design your Logo and packing etc.
