Globe Valve Manufacturers
The globe valve, also called the cut-off valve, is one of the most widely used valves. The reason why it is so popular is that the friction between the sealing surfaces during the opening and closing process is small, it is relatively durable, the opening height is not large, and it is easy to manufacture. , Easy maintenance, not only suitable for medium and low pressure, but also suitable for high pressure.

Frequently Asked Question
Do you have any question?
Globe valves have a very distinct globe shape. The disk, valve stem, and the hand wheel are the moving parts in the valve body. The body is available in three different designs depending on the application as well as three different types of disks.
The medium inlet and outlet flow path of the T Pattern Globe valve are 180° in the same direction. This design has low coefficient of flow and pressure drop. It relies on the valve stem to navigate the valve disc towards the sealing surface of the valve seat, fully shut off the flow.
The globe valve is a kind of throttle valve. The throttle valve is a general term for a large type of valve that can adjust the opening arbitrarily, and the butterfly valve is also a common throttle valve. On-off valve is a general term for valves that can only be opened and closed, represented by ball valves. It is another major type of valve corresponding to throttle valves.
All COVNA globe valves are 100% in-house produced, including mold opening, casting, production, testing and more. At the same time, all products are produced in strict accordance with ISO9001:2015 standards to ensure that the quality of the products is excellent.
Our updates and blog posts
globe-valve | Where the butterfly valve is applicable
{keyword},Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it is about three times that of the gate valve.
globe-valve | How to choose electric butterfly valve
{keyword}.The disc of the butterfly valve is that the disc has a shaft rotating on the position of the valve seat. The angle of the rotation determines the opening and closing degree of the valve.
globe-valve | Gate valve movement
{keyword},Most gate valves are forcibly sealed, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.
