Paramètres de performance principaux
To start with, working temperature ranges from‑196℃ up to +80℃. Next, nominal pressure reaches PN40. What is more, sealing rate meets zero‑leak standard for cryogenic service. Also, butt‑weld ends comply with ASME B16.25 and GB/T standards. Meanwhile, manual handwheel delivers easy open‑close action. Last but not least, each unit passes strict cryogenic cold shock test before shipment.
Points clés de vente
For one thing, long stem structure blocks cold conduction effectively. For another, stainless steel body resists low‑temperature brittle fracture. On top of that, soft‑seat design achieves bubble‑tight shut‑off. In turn, weld connection delivers strong pipeline joint strength. Apart from that, compact angle‑type layout saves installation space. Equally important, this Low temperature globe valve supports fast onsite maintenance.
Avis de vrais clients
Many global buyers give positive real‑world reviews. First, petrochemical clients praise its stable sealing in continuous LNG service. Second, gas plant operators mention smooth handwheel rotation even at‑196℃. Third, project contractors value its compliance with international delivery standards. Even so, clients suggest confirming exact size before bulk purchase.
Large application
Above all, it serves LNG storage and transport pipelines. Next, it fits liquid nitrogen, liquid oxygen, liquid argon production lines. Then, it works for CO₂ cryogenic recovery systems. Additionally, it applies to new‑energy cryogenic equipment. Finally, it supports petrochemical and industrial gas station projects.
En conclusion, notre Low temperature globe valve offers durable, safe control for all cryogenic liquid gas workflows. If you seek dependable cryogenic shut‑off hardware, this Low temperature globe valve is your ideal pick.
