PTFE Lined Butterfly Valve

PTFE butterfly valve is to adapt to some corrosive environment with strong acid, strong alkali, petroleum, chemical, food and other special areas of need, the use of PTFE made of the valve body, has a strong anti-corrosion effect. It can replace the stainless steel body under conventional conditions, with higher cost performance. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, the rotation Angle is 0°~90°, rotate to 90°, the valve brand is fully open.

PTFE (Teflon) butterfly valve can be equipped with AKR electric, BY pneumatic actuator, input control signal (4~20mADC or 1~5VDC) and single-phase power supply can control the operation, can realize intelligent type (regulating type) and switching type. With strong function, small size, light and pleasant, reliable performance, simple supporting, large circulation capacity, especially suitable for the medium is sticky, containing particles, fiber properties of the occasion.

At present, the PTFE butterfly valve, as a component used to realize the on-off and flow control of the pipeline system, has been widely used in petroleum, chemical industry, metallurgy, hydropower and many other fields. In the known butterfly valve technology, its sealing form is mostly sealed structure, sealing materials for rubber, PTFE, etc. Due to the limitation of structural characteristics, it is not suitable for high temperature resistance, high pressure resistance, corrosion resistance, wear resistance and other industries.
