Vacuum shut-off valve-Globe valve series-截止阀厂家-上海冠环阀门制造有限公司

Product Overview

Vacuum isolation valves are suitable for pipelines with working temperatures ≤ 425 ℃ and ≤ 550 ℃, and working media of water, steam, or air, as opening and closing devices; Especially suitable for steam turbine condensation and vacuum negative pressure systems in thermal power plants, playing a vacuum isolation and sealing role.

Product Features
1. The sealing surface has low friction force, easy opening and closing, and automatic compensation function for sealing surface wear.

2. Simple and compact structure, convenient maintenance, and long service life.

3. The valve cover vacuum sealing structure has a self expansion and compression effect, and the sealing is sealed with high-strength expansion materials, completely isolating the system from the atmosphere and having good system airtightness.
