Product Description:
1. Advantages and characteristics of stop valves
Excellent sealing performance
The friction between the sealing surfaces is small, the forced sealing design can achieve zero leakage, and the double sealing structure (such as bellows + packing) further improves safety.
Long service life and low maintenance frequency.
Operation and control advantages
Compact structure, short stroke, fast opening and closing, suitable for cutting off or adjusting flow.
Applicable to medium and high pressure environments, especially stable in media such as steam and oil.
Easy to manufacture and maintain
The parts are highly standardized, and the manufacturing and maintenance costs are low.
Disadvantages : Large fluid resistance, not suitable for high viscosity or particle-containing media; limited adjustment accuracy.
2. Advantages and characteristics of throttle valves
Flow adjustment capability
The valve core design is optimized on the basis of the stop valve, which can adapt to the flow change requirements and is suitable for preliminary flow control.
Often used in conjunction with regulating valves and relief valves to improve system control flexibility.
Simple structure
Short working stroke, fast opening and closing time, and convenient maintenance.
Disadvantages: Only non-precise adjustment can be achieved, and it needs to rely on other valves for cooperation.
III. Precautions for use Stop valve Operation specification Follow the principle of "low in and high out" to avoid reverse installation and seal failure.
It is strictly forbidden to force closing or opening too tight to prevent damage to the valve stem thread or sealing surface.
Installation and maintenance During installation, it is necessary to ensure that the flow direction of the medium is consistent with the direction of the arrow on the valve body.
Avoid long-term half-open state to reduce valve disc wear.
Throttle valve Applicable scenarios Avoid using high-viscosity or impure media to prevent valve core clogging or corrosion.
Need to be used with a filter device to ensure the cleanliness of the medium.
Operation suggestions Adjust the opening gradually during adjustment to avoid sudden impact and deformation of the valve core.
It is recommended to fully open or fully close in situations where no adjustment is made for a long time to reduce wear on the sealing surface.
