Globe Valve Manufacturer in China
The globe valve is due to the small friction force between the sealing surfaces during the opening and closing process, its sealing is achieved by applying torque to the valve stem, the valve stem exerts pressure on the disc in the axial direction, so that the sealing surface of the disc and the sealing surface of the seat are closely pressed together, preventing the medium from flowing along the sealing surface.
This type of globe valve can meet different standards such as GB, JIS, and API.
Sub-Products of Globe Valve
A low-torque, smooth valve is specially designed for liquefied gas, natural gas, steam and ammonia gas pipelines or equipment. The structure takes into account fire protection requirements. The packaging is made of polytetrafluoroethylene, has a reliable seal, and is absolutely leak-proof.
Design and manufacture according to API STD 600; structural length according to ANSI B16.1, flange type and size: 150/3 00/60 0 Lb according to ANSI B16.5, JIS 10K/2 0K according to JIS B2212-B2214, valve contact and testing according to API STD. 598
The sealing surface is welded with Co-based hard alloy, which is wear-resistant, corrosion-resistant, and has good abrasion resistance, and has a long service life.
The valve stem is tempered and nitrided on the surface, which has good corrosion resistance and wear resistance.
The structural form of the valve body of the stop valve is straight, direct current and right-angle. The most common of these is the through-flow type, but it has the highest fluid resistance; The DC type has less fluid resistance and is often used in media containing solid particles or high viscosity.
The Main Structural Characteristics of Globe Valve
The nominal pressure of this globe valve is ≥25.0 MP (class 150), and the central cavity adopts a self-tightening sealing structure. The sealing performance is enhanced as the pressure increases, ensuring sealing performance. The material of the parts and the size of the flange and the weld can be reasonably selected according to the actual working conditions or the requirements of the user, meeting the needs of various engineering projects. The valve stem is tempered and surface nitrided, with good corrosion resistance and anti-corrosion performance.

Some Working Principles of Globe Valve
The hand wheel of the globe valve rotates in a clockwise direction, and the working medium enters from the channel below the valve seat. At this time, the applied sealing force must be equal to or greater than the sum of the necessary pressure and the upward action of the medium on the sealing surface. When the stop valve is opened, the opening height of the valve disc is 25% ~ 30% of the nominal diameter, and the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the stop valve should be determined by the travel of the valve disc.
Note:
- The globe valve only allows the medium to flow in one direction, and it has a directional installation.
- The function of a globe valve is either 0 or 1, either open or closed. In other words, globe valves are only suitable for fully open and fully closed, and it is not recommended to adjust and throttle.
