High platform Threaded ball valve

High platform threaded ball valves are a type of ball valve designed with a high platform structure, which facilitates the direct installation of actuators. They are widely used in various industrial applications for controlling the flow of fluids. The high platform design provides a stable mounting surface for the actuator, ensuring reliable operation and precise control.

Performance Characteristics

  • Superior Sealing: Utilizes hard-sealed or soft-sealed designs to achieve zero leakage, even under high-pressure conditions (up to 1000WOG)314.

  • Durability: Constructed from materials like stainless steel (304/316), WCB, or alloy steel, ensuring resistance to corrosion, high temperatures (-40°C to 200°C), and abrasive media316.

  • Low Flow Resistance: Full-bore design minimizes pressure drop, enhancing efficiency in fluid transfer systems1016.

  • Compact & Lightweight: Threaded connections reduce installation space and weight compared to flanged valves15.

  • Easy Operation: 90-degree rotation mechanism requires minimal torque, compatible with manual handles or automated actuators12.


 Applications

High Platform Threaded Ball Valves are ideal for:

  • Chemical Processing: Handling corrosive fluids like acids, alkalis, and polymers814.

  • Oil & Gas: Pipeline control, refinery systems, and high-pressure fluid isolation16.

  • Water Treatment: Regulating water, steam, and wastewater in municipal or industrial plants3.

  • Power Generation: Managing cooling systems, steam lines, and fuel supply8.

  • Pharmaceuticals: Ensuring sterile flow control in sensitive processes3.

 Installation & Maintenance

Installation Tips:

  • Ensure threads are clean and aligned to prevent cross-threading.

  • Use thread sealant (e.g., PTFE tape) for leak-proof connections15.

  • Avoid over-tightening to prevent damage to valve seats10.

Maintenance Guidelines:

  • Regular Inspection: Check for wear on seals and threads every 6–12 months3.

  • Lubrication: Apply grease to the valve stem for smooth operation12.

  • Leak Testing: Perform low-pressure (0.6 MPa) and high-pressure (5.7 MPa) tests post-installation10.

  • Replacement: Replace damaged seals or balls promptly to avoid system downtime
