Cast Steel Globe Valve

Globe valve is a kind of valve that regulates the flow of fluid in a pipeline or process system by using a disc or plug moves perpendicular to the flow of the fluid. The main components of a globe valve include a valve body, a disc or plug, a stem and a seat. Globe valve has very reliable cut-off function, as well as disc stroke is in direct proportion with seat port opening area, which is very good for flow shutting-off or regulation and throttling. This valve can be installed horizontally or vertically, single-directional, the arrow direction shown on the body should be same as the fluid flow direction.

 

 

Globe valve is suitable to be used on the pipe line of petro-chemical industry, refinery plant, power station. It can also be used for control of air, steam and other corrosive flows. The common applications include chemical and petrochemical plants, oil and gas pipelines, water treatment plants, HVAC systems, pharmaceutical manufacturing, food and beverage processing.

·Operation: Hand wheel, gear, pneumatic and electric actuator

 

 

Globe valves are based on the movement of the disc or plug, which is connected to the stem. When the stem is turned, the disc or plug moves perpendicular to the flow of the fluid, which allows the flow to be regulated by the size of the opening between the disc and seat.

 

 

1.Good flow control: Providing accurate flow control and it can be used to regulate the flow of fluid precisely.

2.High pressure and temperature rating: Designed to withstand high pressure and temperature, which makes them suitable for use in a wide range of application.

3.Versatility: Used in both throttling and isolation application, making them versatile and useful in a variety of industries.

4.Tight shutoff: Providing a tight seal when closed, which makes them ideal for applications where a leak-free shutoff is necessary.
