PTFE Lined Ball Control Valve Features
PTFE (Polytetrafluoroethylene) is a high-performance polymer renowned for its exceptional properties, making it an ideal material for lining valves used in industries that handle highly corrosive substances. Here's a refined explanation of the features of PTFE-lined ball control valves:
1. High Chemical Stability: The combination of a stainless steel body with a PTFE lining provides unparalleled chemical resistance, making the valve suitable for a wide range of corrosive chemical media, including strong acids, alkalis, and oxidants.
2. Full Bore and Floating Ball Design: This design ensures that the valve can close tightly without leakage across the entire pressure range. The side entry feature facilitates easy cleaning and maintenance of the pipeline system.
3. Integrated Casting (Forging): The one-piece construction of the valve stem and the opening and closing parts eliminates the risk of the valve stem being forced out of the pressure parts due to pressure changes, thus enhancing the safety and reliability of the valve in engineering applications.
4. Compact Structure with Reduced Media Retention: The valve features a compact structure with a double D stem head, which minimizes the area where media can accumulate. The use of a high-performance HYPATITE PTFE ball seat and ring-shaped PTFE packing ensures that the valve remains leak-free.
5. Versatile Flanged Lined Ball Valve: Available in two-piece and three-piece flanged designs, these valves can meet various pipeline system requirements and operating conditions. The three-piece design allows for the main valve body to be split, facilitating online replacement and maintenance without the need for pipeline shutdown.
