In the construction of modern transmission systems, the selection of valves that combine high mechanical strength with excellent insulation properties is of critical importance. GLOBTOS pre-insulated valves are an advanced system solution, guaranteeing the highest energy efficiency for your network and trouble-free operation in district heating pipelines laid directly in the ground.

GLOBTOS Pre-insulated Valves: Performance in Trenchless Systems

Our pre-insulated steel ball valves are designed for operation in the most demanding conditions. Thanks to factory-applied thermal insulation, the on-site installation process is significantly shortened, and the integrity of the system remains intact for decades.

As a manufacturer, we focus on parameters that have a real impact on the thermal balance of your investment:

• Insulation: Rigid polyurethane foam (PUR) with high thermal insulation properties.
• Casing: Outer jacket made from high-density polyethylene (HDPE), resistant to moisture and electrochemical corrosion.
• Tightness: Full compliance with EN 488 and leakage Class A in accordance with EN 12266-1.

The Innovative “Dry Stem” – Safety and Protection Against Failures

We fully understand that pipeline projects require flexibility. We offer the manufacture of pre-insulated valves to order, where the stem height (dimension L) is precisely tailored to the installation depth of the pipeline.

Why is the dry stem technology beneficial for your network?

1. Impact protection: Even in the event of mechanical damage or bending of the stem (e.g. by an excavator bucket), the valve remains leak-tight. The medium does not escape to the outside, eliminating the risk of emergency network shutdowns.
2. Adaptability: Because the stem is dry, it can be safely shortened or extended directly on the construction site, adjusting it to the ground elevation levels.
3. Mechanism durability: The stem has no contact with district heating water chemistry, which prevents corrosion and scale build-up.

Customisation: Pre-insulated Valves with Non-standard Stem Height (Dimension L)

We fully understand that pipeline projects require flexibility. We offer the manufacture of pre-insulated valves to order, where the stem height (dimension L) is precisely tailored to the installation depth of the pipeline.

Available actuation options:

• Stem for socket wrench (hexagonal).
• Valves with a handwheel (manual lever).
• Valves with a planetary gearbox (for large bore sizes DN).
• Connections for electric actuator in accordance with ISO 5211.
