Guidelines for Installing Flat Gate Valves in Industrial Systems

The correct installation of flat gate valve is very important, which not only affects the sealing performance and service life of the valve, but also directly relates to the safety and efficiency of the entire system. An improper installation can lead to valve failure, resulting in leakage, damage or even safety incidents. Therefore, mastering the installation points of flat gate valves and taking reasonable installation measures are of great significance to ensure the smooth progress of industrial production. The following will elaborate on the key points that should be paid attention to during the installation of the flat gate valve.
 

Avoid Horizontal Installation

 
Flat gate valve should not be installed horizontally, that is, the large plane of the valve plate is parallel to the ground. Horizontal installation will cause the stem to become a cantilever beam, which is affected by gravity and deformable, thus making the valve plate tilt and sink, unable to fully seal. This not only causes the O-ring and back spring of the seat to not move properly, but also may cause internal compaction and external gaps between the seat and the valve plate, causing internal leakage.
 

Prepare for Installation

 
Before installation, it is necessary to carefully check whether the model, specifications and implementation standards of the valve meet the requirements to ensure that the appearance quality of the valve is intact. In addition, it is necessary to thoroughly clean the pipeline to ensure that the inside of the pipeline is clean and to avoid impurities entering the inside of the valve to affect the use of the effect.
 

Install the Valve Support Reasonably

 
During the installation process, it is necessary to ensure that the valve bracket is installed in a reasonable position to ensure that the valve is firmly and reliably fixed on the pipeline. During installation, the valve should be avoided in a state of excessive distortion or excessive force to prevent damage to the valve structure or resulting in reduced sealing performance.
 

Ensure Sealing Performance

 
When installing the valve, special attention should be paid to the sealing performance between the valve and the pipeline to ensure that no leakage occurs after installation. This includes the correct installation of the seat and seal, as well as the appropriate adjustment of the valve fastening bolts to ensure that the valve parts fit tightly and seal effectively.
 

Ensure Operating Mechanism Flexible and Stable

 
The operating mechanism of the valve must be flexible and reliable after installation to facilitate future operation and maintenance. The handwheel, handle and transmission mechanism should not be used for lifting purposes, and collision or unnecessary external force should be avoided to ensure the long-term service life of the valve.
 

Extra Considerations

 
For flat gate valves with bypass valves, the bypass valve should be opened before opening the valve to balance the pressure difference between the inlet and outlet and reduce the force required when the valve is opened.
 
For the valve with the transmission mechanism, it must be installed and adjusted in strict accordance with the provisions of the product instruction manual to ensure its normal operation and safety performance.
 
For valves that are frequently operated, it is recommended to lubricate and inspect them at least once a month to ensure smooth operation and reduce the risk of failure caused by wear and tear.
 
In summary, strict compliance with the installation requirements and precautions of flat gate valves can not only ensure the reliability and safety of the valve in the industrial process, but also effectively reduce maintenance costs and operational risks to ensure the stable operation of the fluid control system. Reasonable installation and regular maintenance are important guarantees to ensure long-term and efficient operation of equipment.
