Technical description
GLB valves are controlled shut-off valves. They are designed to stop or allow the flow of the medium by external operation, via either the handwheel or the installed drive. If, upon the customer´s request, they are fitted with a regulating cone, they can be used to regulate the flow of the medium. The medium can flow in one direction only. These valves are designed and manufactured to ensure maximum service life and reliability. They are suitable for liquids, gases and steam.
MATERIAL SPECIFICATION
Globe valves are made from carbon and stainless steel. The material type can be adjusted according to the customer´s request to optimally suit the operating conditions.
