Due to the limitation of structural characteristics, it is not suitable for high temperature resistance, high pressure resistance, corrosion resistance, wear resistance and other industriesstandards: en 593, api609, api6din the known butterfly valve technology, its sealing form is mostly sealed structure, sealing materials for rubber, ptfe, etcthe butterfly plate of the butterfly valve is installed in the diameter direction of the pipe
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
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 fieldswith 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 occasionptfe 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
below photos are ptfe lined butterfly valve of tianjin tanghai valve, more information please click here: ptfe butterfly valve
th valve is a professional manufacturer of butterfly valve, gate valve, check valve, globe valve, knife gate valve, ball valve with api, jis, din standard, used in oil, gas, marine industry, water supply and drainage, fire fighting, shipbuilding, water treatment and other systems, with nominal diameter of dn50 to dn1200, nbr/epdm/viton, certificates & approvals: dnv-gl, lloyds, dnv, bv, api, abs, ccsit can replace the stainless steel body under conventional conditions, with higher cost performancein 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 openIndia
