産品詳情

手動高溫高壓Y型截止閥性能特点:

优质材料、合理结构、精湛工艺,按 ASME B16.34标准设计制造。

專爲苛刻工況設計制造,圓滿解決介質高速沖刷、氣泡內爆剝蝕而導致的內漏,使用壽命長。

通過藏少流體系統的泄漏和維護量,達到延長設備的安全運行所需的時間,降低運行成本,從而提高用戶的經濟效益高溫高壓Y型截止閥用于管路中的苛刻工況,具有流阻小,耐沖刷特性,具有密封好、壽命長的優點,根據不同工況,采用碳素鋼、合金鋼、不鏽銅制作,受到用戶的贊許和信賴。

Performance characteristics

The valve has high quality materials, reasonable structure and exquisite craft. The valve is especially designed and manufactured for harsh working onions, it can solve the internal leakage caused by the high speed scouring of the medium and implosion and denudation of the bubble. The valve has very long working life. The standard is ASME B16.34.

The valve can reduce the leakage and the maintenance of the flow system, thus the safe running time of the equipment is extended and the running cost is reduced, the economic benefits of the users is improved.

The valve can be used in the harsh working conditions of the pipeline. It has small flow resistance erosion characteristics, good sea-ling and long service life. The material of the valve is Carbon steel, Alloy steel and Stainless steel according to different conditions.The valve received praise and trust of the users.
