1.ZZY series self operated difference (little) Pressure Control Regulating valve Can be used in nominal pressure PN0.1 , PN10. The difference (little ) presses the regulation of segmenting. From 50mm.WC to 0.1MPa. self operated type difference (little ) Regulating valve of the pressure The use is very extensive, can be used in industry's combustion furnace system, control two kinds of supplies , such as coal gas , air discharge matching , burn in order to reach the ideal. Used in the sealed oil system of the hydrogen-cooled generating set , it is bad to control the pressure among the sealed oil and hydrogen, so as to ensure and seal reliably. Act as Difference presses the valve End not low-voltage the coherent Press the valve a little (Difference presses the valve to shoulder and press, the end is pressed, strength is zero).
2. Self Operated Pressure Regulator Characteristic
2.1 Do not need to stop producing and can go on adjustment of the establishing value;
2.2 There is no packing , exist not gritting at being have , not last activity valve stem,on seal more reliable
2.3 The sensitive element of executive body is extremely sensitive , the pinpoint pressure will be detected out while changing
2.4 The valve body is Stone's form , therefore K, B type body of a kind of valve very in common use
