Most Popular Questions
Expert insights into API 6D valve technology. With 26 years of manufacturing excellence, CARILO provides technical solutions for pressures up to Class 2500 and sizes up to NPS 42″, ensuring 100% operational safety.
Soft-seated valves (PTFE/PEEK) offer Zero-Leakage bubble-tight shut-off for clean services. Metal-seated valves are engineered with Tungsten Carbide coatings to withstand abrasive media and temperatures exceeding 400°C, extending service life by 40% in severe conditions.
These valves feature a fixed ball design with spring-loaded seats. They are the industry standard for high-pressure (Class 600-2500) and large-bore (up to NPS 42") applications, reducing operating torque by 30% compared to floating designs.
In this design, the ball is held by two seats and "floats" downstream to create a seal under pressure. CARILO’s floating series (NPS 1/2" to 8") features an anti-blow-out stem and is optimized for reliable, cost-effective performance in low-to-medium pressure pipelines.
Split body (Side Entry) valves allow for easy maintenance and inspection of internal components. Our 2-piece and 3-piece bolted designs provide superior structural integrity and are fire-safe certified to API 607/6FA standards.
Selection depends on your flow rate (Cv) and pipeline velocity. CARILO offers a comprehensive range from DN15 to DN1000. Our engineering team uses 3D simulation to ensure the selected size minimizes pressure drop and prevents cavitation.
Yes. Our valves are tested for Cryogenic service and high-pressure environments up to Class 2500 (6,000+ PSI). Using NACE MR0175 compliant materials and Fugitive Emission Class A seals, we ensure 100% integrity in the world's harshest environments.
