        Imported steam line pressure reducing valve
        I. Overview of imported steam pipeline pressure reducing valve products
        Brand: US Ouke OKE
        Imported steam pipe pressure reducing valve, also known as cast steel steam pressure regulating valve, means that the valve body material is made of high quality carbon steel WCB, used in steam piping system, and the pressure change after adjusting the valve through the pilot valve The spool opening of the main valve reduces the inlet pressure of the steam line to a desired outlet pressure and stabilizes the valve at the pressure value. The valve relies on the energy of the steam medium itself, so that the outlet pressure automatic diaphragm adopts a new material and greatly processes the working area, so the slight change of the upstream pressure or the downstream load of the valve can be timely and accurately fed back to the main valve diaphragm. Adjust the opening of the main valve to ensure the stability of the downstream pressure.

        Sixth, the import steam pipe pressure reducing valve installation instructions
        1. The steam pipeline pressure relief valve must be flushed and cleaned before installation. In order to prevent the welding slag, oxide scale and other sputum from flowing into the valve, affecting the normal operation of the valve.
        2. The steam pipe pressure reducing valve should be installed in a place convenient for operation and maintenance, and must be installed upright on the horizontal pipe. It should be noted that the flow direction of the medium in the pipe is consistent with the direction indicated by the arrow on the valve body, and must not be reversed.
        3. When installing and using the steam line pressure reducing valve, the shut-off valve of the bypass pipe should be opened to eliminate the mixture of condensed water and soda water in the pipeline to prevent the garbage valve from damaging the pressure reducing valve when the pressure reducing valve is opened. When there is no abnormality, slowly rotate the adjusting screw clockwise to adjust the outlet pressure to the required pressure (according to the valve back pressure). After adjustment, tighten the lock nut and screw the protective cover.
        4. A filter should be installed before the steam pipe pressure reducing valve to prevent debris in the medium from entering the pressure reducing valve and affecting its performance.
        5. There should be a straight pipe before and after the installed pressure reducing valve. The length of the straight pipe in front of the valve is about 600 mm, and the length of the straight pipe behind the valve is about 1000 mm.
        6, steam pipe pressure reducing valve requires inlet and outlet pressure difference must be ≥ 0.2Mpa.
        7. The pipe network of the steam pipe pressure reducing valve must be equipped with a safety valve to prevent damage to the system or equipment caused by the failure pressure of the pressure reducing valve.
