Frequently Asked Questions
What is a DBB structure in ball valves?
DBB stands for Double Block and Bleed. It consists of two seating surfaces that, in the closed position, provide a seal against pressure from both ends of the valve with a means of venting/bleeding the cavity between the seating surfaces.
How does the High-Temperature Performance benefit industrial use?
Our valves are engineered with specialized materials and seals that maintain integrity under extreme heat, preventing leaks and mechanical failure in high-thermal processing environments.
What makes the Fixed Ball Construction reliable?
The fixed ball (trunnion mounted) design uses mechanical anchoring at the top and bottom. This reduces torque and provides a consistent seal even under extremely high-pressure fluctuations.
Is the fire-safe design certified?
Yes, our fire-safe and anti-static designs are built to meet international safety standards, ensuring that the valve maintains a seal during and after a fire event to prevent hazardous leaks.
Can I order specific materials for corrosive environments?
Absolutely. We offer customizable material options including various grades of stainless steel, carbon steel, and exotic alloys to ensure compatibility with your specific medium.
What pipe sizes are compatible with the Heavy Flanged Connection?
Our heavy flanged connections are designed for a wide range of large-diameter pipes. Please contact our technical team with your specific diameter and pressure rating requirements.
