optimization suggestions
*The fluid contains impurities, and a filter screen (mesh ≥ 60) should be installed in front of the valve, and the fluid should not have any solidification or crystallization phenomenon.
*The direction of the valve body marking must be consistent with the flow direction of the medium.
*A diameter ≤ 6mm is a direct acting type, which can be started at zero pressure and is also suitable for low vacuum; A pilot type with a diameter ≥ 8mm must meet the fluid pressure difference before it can be opened.
