GD-J series Manual High vacuum flapper Valve

GD-J25/KF

An angle valve has an inlet and an outlet port which are perpendicular to each other. The angle valve range is characterized by its variety of models and its actuating principles. Manual, pneumatic and electromagnetic angle valves are among the most used in all applications of vacuum technology. Angle valves are widely used to regulate and shut off the water or fluid flow in industrial pipelines. They function reliably in applications including semiconductor production system with chemical and particulate contamination, pumping systems, connection between pumps and so on. Applicable medium is pure air and non-corrosive gas.
