5640Lined Control Valve
5640Lined Control Valve
Brief Description

Type 5640 Lined Control Valve is a single-seat Top Guiding control valve, The wetted parts are adopted high pressure injection molding process, lined poly perfluorinated ethylene (F46) or perfluorinated alkoxy resin (PFA) which is anti-corrosion and aging resistant, packing parts are PTFE bellows and double seal packing, thus it has strong corrosion resistance. As a whole with strong corrosion resistance, long service life, high controlling precision, safe and reliable and convenient maintenance features, Widely used in chemical, petroleum, metallurgy, medicine, electric power industries, and also has automatic control capacity against the liquid medium process of strong corrosive medium such as acid, alkali and toxic and volatile gas.
