The PWBV pipe welding ball valve is a high-performance product developed by Zihigh Valve Company. It features a specially designed dual-seat sealing structure with a double-piston effect, providing reliable sealing, easy operation, and long service life. The PWBV ball valve can be manufactured with specifications up to DN1000mm and is used in heating and gas systems as a control device for opening or closing pipelines.

Specifications:

• Nominal Diameter (DN): 2” (50mm) - 14” (350mm)
• Pressure Class (CLASS): ANSI 150-300 (PN10 - PN50)
• Flow Bore: Full bore & reduced bore (Venturi type)
• Connection Type: Butt-weld, butt-weld * flange, flange, threaded
• Fully Automatic Welding Center

Key Design Features:

• Fully Welded Structure: The valve body is designed as a fully welded unit to eliminate any external leakage of the medium.
• DBB Valve Seat Structure: Double block and bleed, self-relief design, and bidirectional sealing.
• Four-Layer Stem Sealing: Ensures safety and reliability of the valve stem sealing.
• Compact Body Design: The valve is small and easy to install underground, making installation convenient and cost-effective. No large valve well or chamber is needed; only a small cover is required, enhancing safety during road construction.
• Adjustable Body and Stem: The length of the valve body and the height of the valve stem can be adjusted to suit pipeline construction and design requirements.
• High-Precision Ball Processing: The ball is processed with high precision, ensuring smooth operation without interference.
• Aesthetic and Compact: The valve body is smaller and more aesthetically pleasing compared to similar products in the industry.
• 20-Year Warranty: The valve comes with a 20-year warranty under normal operating conditions.

Applications:

• City Gas Systems: For gas transmission pipelines, main lines, and supply pipelines.
• Centralized Heating: For large heating equipment supply pipelines, main lines, and branches.
• Heat Exchangers: For opening and closing pipelines and loops.
• Pressure Regulation Equipment: For natural gas pressure regulation systems.
• Steel Plants: For fluid, gas, and thermal supply pipelines, as well as exhaust gas discharge pipelines.
• Industrial Equipment: For heat treatment, industrial gas, and thermal supply pipelines.
