GB/T584 Marine Cast Steel Globe Valve
The main functions of GB/T584 Marine Cast Steel Globe Valve include cutting off medium flow, preventing backflow and regulating flow.
Overview
Advantages:
Low friction: In the process of opening and closing, the friction between the disc and the sealing surface of the valve body is low, making the valve more durable.
Small opening height: the opening height is only 1/4 of the diameter of the valve seat channel, making the operation more convenient.
Single sealing surface: usually there is only one sealing surface, which is simple in manufacturing process and convenient in maintenance.
Application scenarios and maintenance:
Pay attention to directionality when installing, usually the flow direction of medium is from top to bottom.
Globe valves are usually used in situations where one-way flow is needed, such as hydraulic devices. Because of its large fluid resistance, the sealing reliability is not strong in long-term operation, so it needs regular inspection and maintenance.
