Manual Operated Flanged PTFE PFA FEP fluorine lined globe valve For Acid Industry
FREE-VALVE fluorine-lined globe valve adopts integral rubber encapsulation technology, and the valve body cavity, valve bonnet, valve disc and other parts (i.e., chemical medium overflow parts) in contact with the medium are all made of excellent corrosion-resistant materials as lining or coating materials, and the valve adopts molded lining molding technology, so that the valve has both metal strength and corrosion-resistant characteristics.
FREE-VALVE fluorine-lined globe valve adopts integral rubber encapsulation technology, and the valve body cavity, valve bonnet, valve disc and other parts (i.e., chemical medium overflow parts) in contact with the medium are all made of excellent corrosion-resistant materials as lining or coating materials, and the valve adopts molded lining molding technology, so that the valve has both metal strength and corrosion-resistant characteristics. The sealing surface of the disc adopts flat sealing design, and the valve is mainly used to connect or cut off the medium in the pipeline.
Features
- The valve discand valve stem are designed as one piece part, which can prevent the possibility of the inner parts being flushed out of the valve body caused by the pressure fluctuation of the pipeline.The structure is compact and the use is safe.
- The sealing surface of valve disc adopts flat sealing design,good sealing, small friction between sealing surface.
- The lining material is optional, which can be applied to a variety of media ,the valve has good corrosion resistance.All internal parts are coated with anticorrosive material.
- Fluorine lined stop valves are strictly prohibited from being used as flow regulators, To prevent the high-speed medium flow generated at the throttle from eroding the sealing surface.
- The valves havethree structural forms : Direct flow, oblique type, and angle type, among which direct flow type is the most commonly used. Angle type can be installed at the corners of pipeline systems,this structure saves 90° bends and is easy to operate, and oblique type resistance is the smallest among globe valves,the stem of this type of valve is at an Angle to the channel.
- Pneumatic and electric actuatorcan be configured according to user needs to meet the needs of remote control and program control.
