Select the type and pressure regulating accuracy of the pressure reducing valve according to the usage requirements, and then select its diameter based on the required maximum output flow rate. When determining the air source pressure for the valve, it should be 0.1 MPa greater than the maximum output pressure. The pressure reducing valve is generally installed after the water separator and before the lubricator or setter, and care should be taken not to reverse its inlet and outlet connections. When the valve is not in use, the knob should be loosened to prevent the diaphragm from being deformed by constant pressure, which would affect its performance.
1. For ease of operation and maintenance, this valve is generally installed vertically on a horizontal pipeline.
2. During installation, ensure that the direction of the arrow shown on the valve body is consistent with the flow direction of the medium in the pipeline.
3. To prevent overpressure downstream of the valve, a pressure reducing valve should be installed at least 4 meters away from the valve outlet.
