Trust Valve’s cryogenic service valves are specially engineered to meet the critical demands of low-temperature applications, including liquefied natural gas (LNG) processing, storage, and transportation, as well as industrial cryogenic processes involving liquid oxygen, liquid nitrogen, and liquid argon. These valves maintain exceptional sealing performance and structural integrity under extreme cryogenic temperatures (as low as -269°C/-452°F) while resisting thermal shock and material embrittlement.

Features

Benefits

Cryogenic-Grade Material Selection

Premium materials (e.g., 304L/316L stainless steel, Monel® 400, Inconel® 718) prevent embrittlement at ultra-low temperatures, ensuring long-term mechanical stability.

Double-Packing Seal System

Dual-layer PTFE/graphite packing with a lantern ring provides reliable stem sealing, minimizing fugitive emissions of cryogenic media.

Extended Bonnet Design

Increases the distance between the valve body (low-temperature zone) and the packing (ambient temperature zone), preventing packing freezing and ensuring smooth operation.

Anti-Thermal Shock Construction

Optimized body wall thickness and streamlined internal flow paths reduce thermal stress, avoiding cracks caused by rapid temperature changes.

Fire-Safe Design

Complies with API 607/API 6FA standards, maintaining sealing capability in case of fire, critical for LNG and hazardous cryogenic applications.
