Is it necessary to perform degreasing treatment on cast steel check valves? The main reference is whether the following characteristics are met:
1. Used in high and low temperature environments.
2. Installed in water, acid, or alkaline fluids.
3. Frequent operation, such as valves used for flow control.
If the above conditions are met, the valve needs to undergo degreasing treatment. If the valve has good corrosion resistance and is not easy to adsorb impurities during use, degreasing treatment can be omitted.
