Benefits
- Reliable sealing under pressure increase
- Versatile flow control with L- or T-port configuration
- Compliance with international standards (ASME, API, DIN, etc.)
- High reliability and safety
- Wide range of sealing options
- Easy actuator mounting
- Proven quality
- Extensive customization potential
The floating ball is automatically pressed against the downstream seat by the rising upstream pressure, ensuring stable tightness even under pressure fluctuations.
The design of the flow port allows flow to be directed according to various configurations, enabling switching, mixing, or diverting of media streams in different process modes.
Ensures universal applicability across industries and countries.
Features such as blowout-proof stem, anti-static device, and TA-Luft and ISO 15848-1 compliance make the valve suitable for hazardous media and explosive zones.
Selection of metal, carbon, or soft seat sealing allows adaptation to various pressure, temperature, and media conditions.
DIN/ISO 5211 compliant interface allows simple installation of pneumatic or electric actuators.
Each valve undergoes 100% leak and functional testing, minimizing operational failure risk.
From extreme temperature versions to heating jackets, custom paintwork, and special testing — the product can be tailored to any project requirements.
Applications
- Chemical and petrochemical industries
- Oil and gas industry
- Cryogenic installations
- Power and thermal energy sectors
- Metallurgy
- Facilities with stringent safety requirements
Handling aggressive media, switching and distributing flows of acids, alkalis, solvents, etc.
Reliable performance with hydrocarbons, including at extreme temperatures.
Suitable for LNG, nitrogen, oxygen, and other cryogenic liquids due to design capabilities down to -196 °C.
Used in heat transfer systems and for switching steam and water flows in CHP plants.
Withstand high temperatures (up to +800 °C), ideal for hot process environments.
Used in systems requiring tight shut-off and emission prevention — e.g., pharmaceutical and environmentally sensitive facilities.
