Self Operated Pressure regulating Valve Introduction
GAZZC, GAZZV 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).
Self Operated Pressure Control Regulating valve Characteristic
- Do not need to stop producing and can go on adjustment of the establishing value;
- There is no packing , exist not gritting at being have , not last activity valve stem,on seal more reliable
- The sensitive element of executive body is extremely sensitive , the pinpoint pressure will be detected out while changing
