Technical Information

❓ Frequently Asked Questions

What is the lowest temperature this valve can handle?
This cryogenic ball valve is specifically designed for extreme low-temperature performance, guaranteed to operate reliably at temperatures as low as -196°C.
Why choose a Trunnion-Mounted design for cryogenic applications?
The trunnion-mounted construction provides enhanced stability and mechanical support for the ball, which reduces operating torque and ensures consistent sealing under high-pressure cryogenic conditions.
What are the benefits of the Double Block and Bleed (DBB) technology?
DBB technology allows the valve to seal from both the upstream and downstream sides simultaneously. This enables the cavity between the seats to be vented or drained, providing superior safety and leak prevention.
Which standards does this valve comply with?
Our cryogenic valves meet major global standards including ASME B16.34 and GB/T14925, ensuring they fulfill the rigorous requirements of international industrial applications.
What materials are available for custom orders?
We offer a wide range of high-performance materials including A350 LF2, Inconel 625, and Hastelloy C to suit specific chemical and temperature requirements of your project.
Is every valve tested before shipment?
Yes, each individual valve undergoes rigorous in-house cryogenic testing and pressure trials to ensure it meets our strict quality and safety standards before reaching the customer.
