Shanghai ZZVP-16C independent micro pressure control valve, nitrogen valve, gas pressure reducing valve DN150

ZZVP type automatic micro pressure regulating valve (gas valve) is a need of external energy saving products, compared with the medium pressure change signal using technology in the pipeline, so that the output force balance force actuator and by regulating the media, in order to achieve a stable pressure and differential pressure value. ZZCP-1 type differential pressure valve adopts balanced single seat valve, which has the advantages of stable pressure, high precision and good sealing performance. It is used to control the small differential pressure.

I. ZZVP self powered micro pressure regulating valve(natural gas pressure relief valve)Summary

Model ZZVP self operated micro pressure regulating valve(natural gas pressure relief valve)It is a kind of energy saving product without external energy. The pressure of the medium in the process pipe is compared with the signal, so that the force of the regulating medium and the output force of the actuator are balanced, so as to achieve the stable pressure and differential pressure value. ZZCP-1 type differential pressure valve adopts balanced single seat valve, which has the advantages of stable pressure, high precision and good sealing performance. It is used to control the small differential pressure. ZZCN-10 type differential pressure valve adopts two seat valve, the flow coefficient is large, the spool is positive and inverted, can form two different varieties of products. The product is suitable for various industrial furnace combustion systems to control two kinds of fuel gas mixture flow rate, or used in the hydrogen cooling generator sealing oil system, at the same time, it can also be used for various industrial gas pressure reduction, pressure regulation or automatic control of pressure relief.

ZZVP typezzv(natural gas pressure relief valve)The balance single seat valve can be used to adjust the setting value at any time. Therefore, it is suitable for various industrial furnaces combustion fuel gas, oil in process or oil tank storage gas and heat treatment protection gas micro pressure automatic adjustment and other occasions.ZZC and ZZV50mm.WC to 0.1MPa self differential (micro) pressure regulating valve is a kind of actuator which does not need additional energy. It can be used for nominal pressure PN0.1 and PN10. The differential (micro) pressure can be adjusted by stages. From 50mm.WC to 0.1MPa. It is widely used and can be used in industrial combustion furnace system to control two kinds of materials, such as gas and air flow ratio, so as to achieve ideal combustion. It is used for sealing oil system of hydrogen cooling generator set to control the pressure difference between sealing oil and hydrogen, so as to ensure reliable sealing. When the pressure valve of the low-pressure end through the atmosphere is the micro pressure (differential pressure valve valve pressure, end pressure, force is zero).
Two, product characteristics
Adjust the setting value without stopping production;
No padding, no friction on the upper and lower of the valve stem, and the upper seal is absolutely reliable
The actuators are extremely sensitive and extremely small pressure changes are sensed
The valve body is four way, so K and B can be used as one kind of valve body
