Product Description

Key Features

Safety and Leak-Free Design

Double-Block-and-Bleed (DBB), Anti-Static, Fire-Safe (API 607), Anti-Blowout Stem, and Low Fugitive Emission Packing (ISO 15848) provide comprehensive protection, ensuring maximum safety and leak prevention.

Superior Cryogenic Performance & Sealing Reliability

PCTFE Cryogenic Seat and Lip-Seal Compensation deliver a tight, leak-free seal even in extreme conditions as low as -196°C.

Proven Durability

Deep Cryogenic Treatment for all pressure components and an extended cryogenic stem ensure reliable performance at temperatures as low as -46°C, handling both extreme cold and high-pressure conditions.

In-House Cryogenic Testing

Each valve undergoes rigorous testing in our in-house cryogenic facility, ensuring dependable operation in the harshest low-temperature environments.

Versatile Applications

Ideal for cryogenic fluids like Liquid Helium (LHe), Liquid Hydrogen (LH₂), LNG, Liquid Nitrogen (LN₂), and Liquid Oxygen (LOX), as well as high-flow pipelines and large storage tanks.

Customizable Options

Available in a wide range of sizes and materials (A350 LF2, A350 LF3, AISI 4130, 4140, A182 F304, F316, F316L, A182 F51, F53, Inconel 625, Incoloy 800, Hastelloy C, etc.) to meet diverse industrial requirements.

Frequently Asked Questions
QWhat does Double-Block-and-Bleed (DBB) mean in cryogenic ball valves?
DBB refers to a valve configuration that provides two independent seating surfaces. When the valve is closed, both seating surfaces isolate the pipeline simultaneously while a bleed port between them allows for pressure relief or verification of seal integrity, ensuring zero leakage and maximum safety.
QWhat is the minimum operating temperature these cryogenic ball valves can handle?
Our cryogenic ball valves are designed to operate reliably at temperatures as low as -196°C, thanks to the PCTFE Cryogenic Seat and Lip-Seal Compensation technology. The deep cryogenic treatment applied to all pressure components also ensures reliable performance down to -46°C for standard cryogenic applications.
QWhich cryogenic fluids are these valves compatible with?
These valves are compatible with a wide range of cryogenic fluids including Liquid Helium (LHe), Liquid Hydrogen (LH₂), LNG (Liquefied Natural Gas), Liquid Nitrogen (LN₂), and Liquid Oxygen (LOX). They are also suitable for use in high-flow pipelines and large cryogenic storage tanks.
QWhat materials are available for these cryogenic ball valves?
We offer a broad selection of materials to suit diverse industrial needs, including A350 LF2, A350 LF3, AISI 4130, 4140, A182 F304, F316, F316L, A182 F51, F53, Inconel 625, Incoloy 800, and Hastelloy C. Custom material options are available upon request to meet specific application requirements.
QHow are these valves tested before delivery?
Every valve undergoes rigorous in-house cryogenic testing in our dedicated cryogenic test facility. Each unit is individually tested to verify sealing performance, structural integrity, and operational reliability under extreme low-temperature and high-pressure conditions before shipment.
QWhat certifications do these cryogenic ball valves comply with?
Our cryogenic ball valves comply with internationally recognized standards including API 607 (Fire-Safe design) and ISO 15848 (Low Fugitive Emission Packing), ensuring adherence to the highest safety and environmental standards for industrial valve applications.
