TVN V801 Globe Valve

Overview

The valve is a premier linear motion valve meticulously engineered for both reliable on/off isolation and precise flow throttling applications across demanding industrial environments. Unlike standard gate or ball valves, the valve features a specialized internal disk and seat ring geometry that provides exceptional throttling ability, allowing operators to achieve exact flow rates simply by rotating the handwheel. This level of control makes the valve an indispensable component for complex piping systems where pressure and fluid dynamics must be strictly managed without compromising safety or efficiency.

As the official authorized partner and exclusive regional representative for TVN, Seven Star LLC proudly supplies the valve throughout Oman and the wider GCC region. We ensure that facility managers and procurement engineers receive genuine, high-quality valve equipment backed by our local technical support and comprehensive warranty services, essential for maintaining uninterrupted and safe industrial operations.

Measurement and Operating Principle

At the core of the valve is its highly effective linear motion mechanism. The operational principle relies on the gradual change in spacing between the internal disk and the stationary seat ring. When the operator rotates the handwheel, the valve stem precisely raises or lowers the disk. This linear vertical movement directly alters the flow cross-section, which grants the valve its superior throttling capabilities compared to quarter-turn valves.

Because the fluid must change direction as it passes through the valve body, the TVN V801 Globe Valve inherently produces a higher pressure drop even in the fully open position. However, this design trade-off is what enables the TVN V801 Globe Valve to deliver unparalleled flow modulation. Whether handling gases or liquids, the TVN V801 Globe Valve ensures that flow rates can be adjusted to any desired level smoothly, securely, and reliably.

Engineering Design of the TVN V801 Globe Valve

The structural integrity of the TVN V801 Globe Valve is built to withstand extreme industrial conditions. Available in a comprehensive size range from DN15 up to DN350, the valve body is constructed from highly durable materials, typically GG25 (Cast Iron) or GGG40 (Ductile Iron), ensuring exceptional resistance to internal pressures and external mechanical stress. The critical moving components, namely the disk and the valve stem, are forged from robust AISI 420 or A105 steel, guaranteeing longevity even under continuous throttling operations.

Furthermore, the TVN V801 Globe Valve is fully compliant with the rigorous EN 13789 design standard. The exterior is coated with a premium industrial epoxy finish, providing a crucial layer of defense against environmental corrosion. To ensure absolute leak tightness, the TVN V801 Globe Valve utilizes high-grade graphite sealing materials, which maintain their integrity across the valve’s extensive pressure ratings of PN 10, PN 16, and PN 25.
