Adjustable pressure reducing valve selection standard

1, within a given pressure range of the spring, so that the outlet pressure between the maximum and minimum pressure relief valve can be continuously adjusted without jamming and abnormal vibration; 2, for the soft-sealed valve, the provisions of Of the time there shall be no leakage; for the metal seal of the valve, the leakage should not exceed 0.5% of the maximum flow; 3, the outlet flow changes, the direct effect of the export pressure deviation of not more than 20%, the pilot The formula is not more than 10%; 4, the inlet pressure changes, the direct effect of the export pressure deviation of not more than 10%, the pilot is not more than 5%; 5, usually adjustable valve after the valve pressure should be less than the valve pressure 0.5 times; 6, the valve is widely used in steam, compressed air, industrial gas, water, oil and many other liquid medium equipment and piping can be used, the medium flows through the outlet of the valve Of the amount, generally expressed as mass flow or volume flow; 7, bellows direct-acting pressure reducing valve for low pressure, medium and small diameter steam medium; 8, membrane direct acting pressure reducing valve for medium and low pressure, medium and small caliber air , Water medium; 9, pilot pressure reducing valve For a variety of pressure, a variety of caliber, a variety of temperature steam, air and water media, if made of stainless steel, can be applied to a variety of corrosive media; 10, the pilot bellows-type valve for Low pressure, medium and small caliber of steam, air and other media; 11, the pilot membrane valve, suitable for low pressure, medium pressure, medium and small diameter steam or water and other media; 12, reducing valve inlet pressure fluctuations should be controlled at the inlet pressure Given the value of 80% to 105%, such as over this range, the performance of the pre-decompression will be affected; 13, the valve is usually less than the valve after the pressure should be less than 0.5 times; 14, A file of spring only in a certain range of outlet pressure range, beyond the scope of the spring should be replaced; 15, the medium temperature is relatively high occasions, the general choice of pilot-piston valve or pilot bellows-type valve; For air or water (liquid) occasions, the general should choose direct-acting membrane-type pressure reducing valve or pilot membrane valve; 17, the media for steam occasions, should choose the pilot piston or pilot bellows-type valve; 18, in order to operate, adjust and dimension Convenience, should be valve is generally mounted on a horizontal pipe.
