Smooth stem flange double eccentric butterfly valve, valve body butterfly plate CF3M, valve stem F51, sealed RPTFE, 8-inch diameter, 150LB pressure rating. The double eccentric structure has excellent sealing and low wear, and the flange connection is easy to install and maintain. It is suitable for efficient flow control in multimedia pipelines, chemical, municipal and other fields.
Smooth stem flange double eccentric butterfly valveIt is a high-performance butterfly valve designed with a double eccentric structure, combined with a smooth rod and flange connection form, which has excellent sealing performance, mechanical performance, and installation convenience. It is widely used in various medium pipeline systems such as water, oil, gas, etc. in the fields of chemical, petroleum, municipal, energy, etc., to achieve efficient opening and closing control of the medium.
Valve body butterfly plateMade of CF3M stainless steel material, it has reliable corrosion resistance and can work stably in harsh media environments such as strong acids and alkalis, ensuring the structural strength and service life of the valve body.
valve stemF51 duplex stainless steel is selected, which combines high strength and corrosion resistance, and can withstand the pressure and torque of pipeline media, avoiding problems such as deformation and corrosion of the valve stem during long-term use.
sealing elementMade of RPTFE (polytetrafluoroethylene) material, it has corrosion resistance, sealing performance, and high temperature resistance, and can adapt to a temperature range of -200 ℃ to 260 ℃, ensuring the sealing reliability of the valve under various working conditions.
Double eccentric structureCompared to ordinary butterfly valves, the double eccentric design significantly reduces the contact friction between the butterfly plate and the valve seat during the opening and closing process, effectively extending the service life of the sealing pair and improving the sealing performance, achieving zero or trace leakage sealing effect.
Connection between light rod and flangeThe light rod design simplifies the valve stem structure and facilitates maintenance and operation; The flange connection method conforms to the general pipeline installation standards, with easy installation and disassembly, and can quickly adapt to existing pipeline systems.
Nominal diameter: 8 inches
Pressure rating: 150LB
Applicable media: various media such as water, oil, gas, etc
Applicable temperature: -200 ℃ to 260 ℃ (determined by the temperature resistance of the sealing component RPTFE)
