GLOBTOS standard ball valves are the foundation of safe and efficient district heating and industrial systems. Designed for years of maintenance-free operation, they combine precision workmanship with the highest quality materials, ensuring full control over media flow under any conditions.

Industrial Durability: Why Choose GLOBTOS Valves?

In transmission installations, there is no room for compromise. Our steel ball valves are premium-class products, optimised for resistance to variable pressures and high temperatures.

By choosing GLOBTOS valves, you are investing in:

• Top-grade materials: Valve bodies manufactured from certified P235GH boiler steel, characterised by excellent weldability and mechanical stability.
• Stainless shut-off element: A ball made from AISI 304 stainless steel guarantees that the valve does not become fouled with deposits and maintains smooth operation for decades.
• Class A tightness: Every valve undergoes rigorous testing in accordance with EN 12266-1, providing assurance of complete media shut-off.

Connection Types and Mounting Variants

We offer a wide range of solutions that allow perfect adaptation of the valve to the specific requirements of the pipeline:

1. Butt-weld ball valves (W): The most popular choice in district heating networks. The fully welded body construction eliminates the risk of external leaks and requires no additional joint sealing.
2. Flanged ball valves (F): Ideal for installation in heat chambers, substations, and process systems where easy maintenance disassembly is required.
3. Hybrid variants (WF): Weld-flange ball valves, used at transition points where a pipeline connects to flanged valves.

Flow Specification: Full Bore vs. Reduced Bore

Selecting the correct flow characteristic is critical for network hydraulics and the maximum energy efficiency of your installation.

• Full Bore: The bore diameter of the ball is identical to the pipe diameter. This solution minimises flow resistance and pressure drops, which is essential on main transmission mains.
• Reduced Bore: A valve with a smaller ball diameter, making it a lighter and more economical solution for building connections and branch lines where minor pressure losses are acceptable.

Operating Parameters and Applications

GLOBTOS standard valves are designed for use in demanding environments:

• Media: District heating water, glycol, steam, industrial oils.
• Pressure ratings: PN16, PN25, PN40.
• Operating temperature: from -20°C to +150°C (optionally up to +200°C with specialist seals).
• Sealing: Carbon-reinforced PTFE (PTFE+C), resistant to ageing and district heating water chemistry.
