Bushing: PTFE O-ring: EPDM, NBR
Drive: Handle, Gearbox, Pneumatic actuator, Electric actuator
End Connection: Flange, Wafer
1. It has simple structure, small size, short structure length, small volume and light weight.
2. When fully opened, the effective flow area of the valve seat channel is large and the fluid resistance is small.
3. It is convenient to open and close, and the flow characteristic is close to a straight line, with good adjustment performance.
4. The opening and closing torque is small, because the butterfly plates on both sides of the shaft are basically equal to the effect of the medium, and the direction of the torque is opposite, so the opening and closing is relatively labor-saving.
5. The sealing surface materials are generally rubber and polytetrafluoroethylene, so the low pressure sealing performance is good.
6. The valve body is made of stainless steel with good corrosion resistance, oxidation resistance and longer service life.
