1. Product introduction
Detailed characteristics and working principle of the globe valve:
### How it works:
- ** Linear motion ** : The valve disc moves in a straight line on the center line of the fluid to realize the opening and closing of the valve.
- ** Full open full Close ** : The globe valve is designed to be fully open or fully closed and is not suitable for flow regulation or throttling.
### Structural Features:
- ** Forced seal ** : The globe valve is a forced seal valve, and pressure needs to be applied when it is closed to ensure that the disc sealing surface does not leak.
- ** Stem design ** : The diameter of the stem needs to be large enough to withstand the large torque required to close the valve and prevent the top of the stem from bending or damaging.
### Operating characteristics:
- ** Self-sealing valve ** : In recent years, the emergence of self-sealing valves has changed the flow of media, making the force required to close the valve reduced, and the force required to open the valve increased, so that the stem diameter can be reduced.
- ** Medium action ** : Under the action of the medium, this valve form is more compact and improves the sealing performance.
### Installation and maintenance:
- ** Opening height ** : When the opening height of the valve disc reaches 25% to 30% of the nominal diameter, the flow rate reaches the maximum, indicating that the valve is fully opened.
- ** Full open position ** : The full open position of the globe valve should be determined by the stroke of the valve disc to ensure correct operation of the valve.
### Application requirements:
- ** Flow direction regulations ** : China's valve "three" specifies the medium flow direction of the globe valve, all top-down.
### Safety Features:
- ** Sealing performance ** : When the globe valve is closed, there is no leakage between the sealing surfaces by applying pressure, which is suitable for occasions where the fluid needs to be strictly cut off.
### Specifications and Standards:
- ** Multiple specifications ** : Valves are available in a variety of sizes and pressure classes to meet the needs of different pipe diameters and fluid pressures.
- ** Standard compliance ** : The production process follows the relevant international and domestic standards, such as ISO, DIN, ANSI, GB, etc.
