Application fields

Our valves are designed to deliver high performance, safety, and reliability even under complex operating conditions. With certified materials, advanced construction solutions, and extensive customization options, we meet the needs of the main industrial sectors.

Utility Service (-46°C / +200°C)

Valves for general applications with non-corrosive fluids. Wide temperature range, ideal for gas networks, water treatment plants, air and diesel distribution. A well-stocked warehouse and fast logistics ensure prompt deliveries.

Extreme Heat Service (>200°C)

Constructed with heat-resistant materials and graphite seals, these valves ensure safety and operational continuity in thermal plants, power generation stations, and the chemical or metallurgical industries. Designed for environments with high thermal loads.

Low Temperature Service (down to -100°C)

Valves for harsh cold environments, made of stainless steel, duplex, and super duplex alloys. Extended stem for thermal insulation and seats in PEEK, RPTFE, or PCTFE ensure stable performance in critical sectors such as industrial gases and pharmaceuticals.

Cryogenic Service (down to -196°C)

Optimized solutions for liquefied gases (LNG, oxygen, nitrogen, argon, helium). Extended stems up to 250 mm, Lipseal seals, and components resistant to thermal shock ensure reliable functionality in extreme cryogenic conditions.

Corrosive Service

Valves for chemically aggressive fluids, made of corrosion-resistant alloys (duplex/super duplex) and equipped with zero-leakage seals. Gaskets are selected based on the specific fluid to ensure integrity and long-term durability.

Hydrogen Service

Valves designed for hydrogen applications, made of stainless steel, duplex, and super duplex alloys. Equipped with specific seals using FKM AED O-rings and compliant with ISO 15848 for fugitive emission control.
Suitable for high-pressure applications, they offer reliable performance throughout the entire hydrogen process cycle. Configurations can be customized for plants and processes related to the energy transition.
