Double Seated Globe Valve

Double Seated Globe Valve

Double seated globe valves are mainly used to regulate and cut off the flow of media in pipelines. Compared with single-seat stop valves, double-seat stop valves have smaller fluid resistance when opening and closing, and more linear flow characteristics, so they are particularly effective in situations where precise flow regulation is required.

The Main features Of Double Seated Globe Valve

 

 

Excellent sealing: The double-seat design ensures higher sealing performance and is suitable for high-pressure and high-temperature environments.
Linear flow characteristics: The fluid flow is smoother and easy to adjust accurately.


Low fluid resistance: Compared with single-seat valves, the resistance when the fluid passes is smaller, which improves the energy efficiency of the system.


Multiple material options: Stainless steel, carbon steel, plastic and other materials can be selected according to the media characteristics and working conditions.


Simple maintenance: The valve structure is reasonably designed and easy to disassemble and repair.

 

FAQ

 

1. What is the working principle of the double seated globe valve?
The working principle of the stop valve is to control the flow of fluid by making the valve core and the valve seat contact or separate through the up and down movement of the valve stem. When the valve is fully closed, the valve core presses the valve seat tightly to achieve sealing; when the valve is open, the fluid flows through the gap between the valve core and the valve seat.

 

2. What is the difference between a stop valve and other valves?
The stop valve is mainly used to cut off and adjust the flow, with good sealing performance and low fluid resistance. Compared with the ball valve, the stop valve has better adjustment performance, but the opening and closing speed is slower. Compared with the gate valve, the stop valve is suitable for flow regulation, while the gate valve is more suitable for full opening or closing.

 

3. Can the stop valve be used in high temperature and high pressure environments?
Yes, the stop valve can be suitable for high temperature and high pressure environments according to different materials and designs. Choosing the right material and specifications can ensure the normal operation of the valve under harsh conditions.
