Brief Introduction.
 
ZZCP Regulating Valve is a self operated regulating valve,its special advantage is that there is no need for any external power source, it can use the medium's flow force to realize the function of pressure regulating automatically when the medium flow through the actuator,it is mainly used for burning furnace system to control the mixing of coal gas and air,or oil sealing system in Hydrogen cooled generator set to control the pressure differential between sealing oil and hydrogen to realize reliable sealing,besides,pump bypass and other systems can also use it,compared with other regulating valves,it has following features:
 
1.Adjust the preset value but no need to stop production.
2.Packing is not installed in the valve,so there's friction when the stem move up and down,top sealing performance is very good.
3.The elements of actuator are high-sensitive,even micro pressure change can be sensed.
