1. The Check Valve is adjusted to set the value to the opening pressure required by the user. If the user has a spring pressure level, the stamping parts factory should base it on the lower limit of the pressure range.
2. When using a
Universal Valve installed in front of protected equipment or before installation, you must readjust the installation site to ensure that the constant pressure value of the Check Valve meets the requirements.
3. It means that within the spring operating pressure range on the nameplate, you can adjust the opening pressure by rotating the adjusting screw to change the spring compression. Black - Before turning the adjustment screw, open the
Pressure Valve and the inlet pressure should be reduced to 90% to prevent the optical drive from rotating when you turn the adjustment screw, thus damaging the sealing surface.
4. To ensure accurate opening pressure value, adjustments should be made to the media, such as media type and temperature, as close as possible to the actual working conditions. The opening pressure often changes with changes in media type, especially when the media aggregation state is not the same (eg from gas phase to liquid phase). As the operating temperature increases, the opening pressure is generally lower. At room temperature, adjust to the highest temperature, and the pressure set at room temperature should be slightly higher than the value required to open the pressure value. To what extent the choice of valve construction and materials depends, it should be based on the manufacturer's instructions.
