Durable Blowout-Proof DesignThe single piece ball valve is engineered with a blowout-proof stem, maximizing operator safety and minimizing risk under rigorous working conditions. This design enhances reliability, especially in high-pressure environments up to 25 Bar, providing confidence in critical industrial applications.
Versatile Connection OptionsAvailable in threaded, socket weld, and flanged end connections, the valve integrates seamlessly with piping systems across industries. Manufactured to ASME/ANSI B16.5, it accommodates installation flexibility, supporting various project requirements for water, oil, and gas media.
Long-term Performance and ReliabilityTested to API 598 standard and built for a lifespan of up to 50,000 cycles, this valve delivers consistent operational excellence in chemical, petrochemical, and water treatment sectors. The PTFE seat ensures superior sealing, while the polished stainless steel body resists corrosion for prolonged service.
FAQ's of Single Piece Ball Valve:
Q: How does the blowout-proof stem design enhance safety in this ball valve?
A: The blowout-proof stem prevents accidental ejection of the stem under high pressure, ensuring safer operation for personnel and reducing the risk of failure during service. This design is especially beneficial in demanding industrial environments.
Q: What is the recommended process for installing this ball valve to ensure optimal performance?
A: Install the valve using appropriate end connections (threaded, socket weld, or flanged) according to pipeline specifications, and verify compatibility with ASME/ANSI B16.5 standards. Ensure that the ISO 5211 pad is properly aligned if mounting actuators. Conduct a leak test as per API 598 after installation.
Q: When should the ball valve be chosen for an application involving high pressure or corrosive media?
A: The single piece ball valve made from CF8/CF8M/SS304/SS316 stainless steel is suitable for high-pressure (up to 25 Bar) and corrosive media applications due to its robust construction and PTFE seat, which resists chemical degradation and ensures reliable sealing.
Q: Where can this valve be utilized within industrial settings?
A: It is used in industrial, chemical, petrochemical plants, and water treatment facilities, especially where full bore flow, tight shut-off, reliable manual control, and versatile installation options are required.
Q: What benefits does the PTFE seat provide over other seat materials?
A: PTFE seats deliver excellent chemical resistance, minimal friction, and superior sealing, resulting in low leakage (Class VI), reduced maintenance, and prolonged valve life even in harsh working conditions.
Q: How can users ensure long service life and reliable operation of this ball valve?
A: Regularly inspect the valve for signs of wear, operate within recommended pressure and temperature limits, and maintain cleanliness of the handling mechanism and media flow path. Scheduled maintenance and adherence to API 598 test procedures help ensure optimal performance over 50,000 operation cycles.
