Whether the angle seat valve has directionality can be determined by the direction of installation and the direction of medium flow. There will be an indication arrow in the direction of installation. Attention should be paid when installing. If the direction is not correct, the whole effort will cost and the service life will be affected. In fact, there are instructions for the directional operation of the installation, and the operation through the diagram in the manual is not a big problem. As long as the installation personnel are familiar with it The other point is the flow direction of the medium. Let’s take a look at it again.
When the flow direction a is selected for the angle seat valve, the service life of the product can be improved if the flow direction is selected. If the working medium is liquid, the flow direction should be selected to prevent hammer impact; when its diameter is 15mm, 20mm, 25mm, the working pressure must be below 0.3MPa, otherwise double acting actuator must be selected. When the diameter of the actuator is 32mm and 40mm, the size of the double acting actuator should be 100 mm. For products with a diameter of 50 mm, the size of double acting 125mm shall be selected. In addition, when the working medium is steam or gas, the flow sealing performance of the product can be improved. However, because the V-shaped sealing ring in the valve body contacts with the working medium for a long time, the service life of the product will be affected. In addition, when the working medium is liquid, it will not be impacted by hammer.
