低温グローブバルブ、ロングステム溶接、極低温LNG遮断制御
これ Low temperature globe valve follows GB/ASME standard, DN15‑DN50, CF8/CF8M stainless steel. It suits LNG, LN2, LO2, LAr, CO₂ cryogenic pipelines. It delivers tight shut‑off for liquid gas in petrochemical and energy projects from China manufacturer.
Low temperature globe valve: Reliable Long‑Stem Cryogenic Shut‑off Solution
私たちの Low temperature globe valve brings stable performance for ultra‑low‑temperature working conditions. First of all, it adopts extended long stem design. Besides, it prevents cold transfer to handwheel parts. Furthermore, it keeps smooth manual operation under‑196℃ environment. In addition, this valve fits butt‑weld installation. Moreover, it works for multiple liquefied industrial gases.

主要性能パラメータ
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.
主なセールスポイント
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.
実際の顧客からのフィードバック
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.
