Underground Radiation type Welded ball valve

Fully Welded Underground Ball Valve - Product Overview The Fully Welded Underground Ball Valve is a high-performance valve specifically designed for buried pipelines, widely used in natural gas, oil & gas, chemical, and municipal gas systems . Its fully welded body eliminates bolted connections, ensuring long-term leak-free operation underground. The valve is operated via an extended stem or gear mechanism , allowing ground-level control and remote operation. Working Principle The valve operates by rotating a hollow spherical ball with a bore through the flow path. When the valve is open , the bore aligns with the pipeline, allowing fluid to pass with minimal pressure drop. When the valve is closed , the ball rotates 90°, blocking the flow completely. The floating ball design ensures tight sealing under pressure, while trunnion-mounted options are available for larger diameters and higher pressures. Extended stems transmit the torque from the ground-level operator to the underground ball, ensuring precise control. Material Selection Body Material : Carbon Steel, Low-Temperature Steel, Stainless Steel, Duplex Stainless ...

Compared to traditional pig launchers and receivers, pigging valves are compact, space-saving, and allow fast pig launching or receiving, improving operational safety and efficiency. Key functions: Launching or receiving pipeline pigs Removing deposits such as wax, scale, or rust from pipeline interiors Supporting in-line inspection pigs for pipeline integrity assessment Reducing operational footprint and installation cost Working Principle The pigging valve has a specially designed internal chamber and switching mechanism. When open, the valve aligns the pig chamber with the pipeline bore, allowing the pig to enter or exit the line. When closed, the chamber is isolated from the pipeline, enabling safe loading or removal of the pig. ...

Integral Block Bleed Valves

Integral Block and Bleed Valves – Comprehensive Overview Integral Block and Bleed Valves are compact, high-integrity valve assemblies designed to isolate and vent process fluids in a single, integrated unit. Unlike traditional multi-valve arrangements, the block and bleed function is built directly into the valve body, reducing the number of potential leak paths, simplifying installation, and improving overall system safety. These valves are widely used in instrumentation systems, chemical processing, and energy production where precision and reliability are essential. Typical Operating Conditions Integral block and bleed valves are commonly applied in situations requiring both secure isolation and controlled venting: Instrumentation Lines – Isolating pressure transmitters, gauges, and switches for maintenance or calibration without shutting down the main process. Chemical Injection Systems – Preventing backflow and ensuring safe disconnection of injection lines. Hydraulic and Pneumatic Control Panels – Providing quick shutoff and venting in control circuits. Sampling Systems – Allowing safe withdrawal of process ...

Forged Steel Trunnion Mounted Ball Valve

Forged Steel Trunnion Mounted Ball Valve – Comprehensive Overview A forged steel trunnion mounted ball valve is a heavy-duty valve designed for reliable shutoff and control in high-pressure, high-temperature, and demanding process conditions. Unlike floating ball designs, the ball in a trunnion-mounted configuration is supported at both the top and bottom, reducing operating torque and minimizing seat wear. The use of forged steel enhances mechanical strength, structural integrity, and resistance to pressure-induced deformation, making these valves ideal for critical applications in the oil & gas, petrochemical, power generation, and industrial sectors. Typical Operating Conditions Forged steel trunnion mounted ball valves are commonly used in: High-Pressure Pipelines – Transporting crude oil, natural gas, refined products, and chemical fluids. Offshore and Subsea Systems – Handling extreme pressure, corrosive seawater exposure, and space-limited environments.
