GB Cast Steel Grey White Color 425℃ Steam Medium Y Strainer Valve
Usage:
Cast steel filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, urban, household and other gas fields. Cast iron filter is an indispensable device on the transmission medium pipeline, usually installed at the inlet of pressure relief valve, pressure relief valve, positioning valve or other equipment, to eliminate impurities in the medium, in order to protect the normal use of valves and equipment, reduce equipment maintenance costs.
When the fluid enters the filter with a filter element, the impurities are blocked by the filter element, and the clean filter gas is discharged from the filter outlet. When it is necessary to clean, as long as the filter cylinder is disassembled, the filter element is taken out, and then it can be reloaded after cleaning. Therefore, the use and maintenance of cast iron filter is extremely convenient.

Precautions for storage, installation and use
1. This product shall be stored in a dry warehouse, and it is strictly prohibited to store it in the open air.
2. The product is often installed at the inlet of pressure reducing valve, pressure relief valve, hydraulic control valve or water gas equipment.
3. It should be installed at a distance of 6-10 times the diameter of the protected valve.
