The quality of stainless steel Check Valve is related to many factors, but because many people do not judge, it is easy to cause people to buy inferior products. So how should the quality of stainless steel exhaust valves be judged?
1. Opening and closing speed
The opening and closing speed is expressed by the time required for the valve to complete an opening or closing action. Generally, there are no strict requirements on the opening and closing speed of the valve, but some working conditions have special requirements for the opening and closing speed. If some require rapid opening or closing to prevent accidents, some require slow closing to prevent water hammer, etc. This should be considered when selecting the valve type.
2. Action sensitivity and reliability
This refers to the sensitivity of the valve to respond to changes in media parameters. For valves with specific functions such as throttle valves, pressure reducing valves, and regulating valves, as well as valves with specific functions such as safety valves and traps, their functional sensitivity and reliability are very important technical performance indicators.
