Precautions for the installation and maintenance of stainless steel gate valves
Thread Content
Stainless steel gate valves are a type of valve that is commonly used in our daily work and production. So, what are the things to keep in mind when installing and maintaining them? Precautions for installation and maintenance: 1. The handwheel, handle, and transmission mechanism must not be used for lifting, and collision is strictly prohibited. 2. Double-plate gate valves should be installed vertically (i.e., the valve stem is in a vertical position with the handwheel at the top). 3. For gate valves equipped with a bypass valve, the bypass valve should be opened first before opening the valve (to balance the pressure difference between the inlet and outlet and reduce the force required to open it). 4. Gate valves equipped with belt drive mechanisms shall be installed in accordance with the provisions of the product instruction manual. 5. If the valve is used frequently for opening and closing, it should be lubricated at least once a month.
In reality, few people bother to clean them; they’re just used once they’re installed, with no maintenance done
That’s the problem: the maintenance cost of a valve is often higher than its value
