Micro-Pressure Self-Operated Control Valve （Automatic control of micropressure pressure in industrial production）

      ZZVP micro pressure self operated regulating valve is an energy-saving regulating valve that automatically adjusts based on the pressure changes of the regulated medium itself. It can be applied to combustion systems, generator and air compressor shaft sealing systems, with P ≤ 0.1MPa in front of the valve and<10KPa behind the valve, for continuous control. Its characteristic is that the set value can be adjusted during equipment operation: no filling, sensitive action: able to detect small pressure changes. Widely used in automatic control of micro pressure in industrial production. A pressure reduction ratio greater than 100 requires two stages of pressure reduction. This series is divided into two types: ZZVP/N-16B normally open (valve closes when control pressure exceeds the set value) and ZZVP/N16K normally closed (valve opens when control pressure exceeds the set value).

Product features:

1.The valve body flow channel and wall thickness are analyzed using CAE structural strength analysis. While meeting the design requirements and strength of minimum wall thickness, weight is minimized as much as possible to save costs and achieve high economic efficiency.

2.The valve body passage is S-shaped, with small pressure drop loss and large flow rate.

3.Utilizing medium pressure regulation to control pressure difference, with good continuous control.
