PURPOSE AND SCOPE
Three-way globe valves are used as locking and locking-controlling arms of industrial pipelines in different industries. Valves operating mediums are natural and liquefied gas, oil products, water, carbon dioxide and other mediums, which are neutral to valve materials.
ADVANTAGES AND DETAILS OF CONSTRUCTION:
- globe valves have full-bore construction and are made in the version with manual drive;
- valve construction is modular, it consists of one-piece body and three or more joints connected with body by stud bolts that provides its maintainability;
- depending on the operating conditions three-way globe valves are made with L- or T-shaped pass on the plug (globe);
- valve operation scheme (supply and overlapping of operating medium in all positions of the locking device) are agreed while ordering;
- globe valves are made with manual (mechanical) drive, with pneumatic and electric drive.
