With a minimum cracking pressure of 270 Pa and differential pressure lower than 200 Pa, these are the basic parameters of all check valves, and all check valves are based on the guide sleeve structure.
Designed with a patented guide sleeve structure, our Micro Pressure Check Valve Series achieves gas sealing zero leakage with tailored low differential opening for each valve size. It reduces system energy consumption and fugitive emissions, helping industrial enterprises meet energy-saving requirements and carbon neutrality targets. All models follow the same core technical principles.
The series includes four tailored models: zero-leakage check valves, micro-resistance check valves, micro differential pressure check valves, and self-centering check valves. Parameters and structures are fine-tuned separately to fit diverse application requirements. All models feature a minimum cracking pressure of 270 Pa and differential pressure lower than 200 Pa. Micro-resistance and micro differential check valves are built for ultra-low flow resistance, delivering smooth media flow and minimal pressure loss.
Typical scenarios: precision gas regulating pipelines, low-flow liquid transfer, laboratory fluid control systems, gas circulation loops.
Adopting a self-aligning guiding structure, it resists vibration and pulse impact, and can operate stably in pipelines with continuous mechanical vibration and unstable fluid flow.
Typical applications: petrochemical process pipelines, offshore engineering, marine pipelines, compressor skids, pump discharge lines.
The unique design effectively suppresses fluid turbulence. The guide sleeve and radial limiting structure eliminate disc flutter and irregular movement caused by turbulence, ensuring stable valve operation and long-term pipeline sealing integrity.
This series serves high-precision micro-pressure applications worldwide, including chemical processing, biopharmaceuticals, power generation, VOC emission control, ultra-pure water transfer, and photoresist handling systems.
The valves deliver energy-saving and emission-reduction performance to meet the demands of European and American industrial projects. Compliant with EU CBAM, EU ETS and global corporate ESG evaluation standards, it provides practical green compliance support for end users. The underlying working mechanisms are detailed below:
The unique micro-pressure actuating structure greatly lowers pipeline starting pressure requirements. All valves have a minimum cracking pressure of 270 Pa and differential pressure lower than 200 Pa. Standard test conditions: working pressure 0.01–0.2 MPa, ambient temperature 5–40°C. Compared with pipelines equipped with traditional check valves, power consumption of supporting pumps, compressors and other power equipment can be reduced by 15%–25%.
Energy-saving performance varies with temperature, pressure and medium. Actual performance depends on field working conditions. This parameter is for reference only. It cuts long-term power and fuel consumption and improves the efficiency of the whole production system.
The optimized internal flow channel reduces pressure loss and fluid resistance. No extra energy is required to overcome excessive pipeline resistance during medium delivery, cutting ineffective energy loss and continuous operating energy consumption.
Gas sealing zero leakage fully blocks escape and volatilization of VOC, greenhouse gases, toxic chemicals and high-value process media. It meets strict emission standards of EU and US EPA and avoids heavy fines for non-compliance.
Prevent environmental pollution and material loss caused by medium leakage. For high-purity and high-value working conditions such as biopharmaceuticals and photoresist processes, eliminate material scrapping and subsequent environmental treatment costs caused by leakage.
For customers with carbon compliance requirements, energy-saving and emission-reduction data can be submitted to third-party institutions for verification, for carbon quota accounting and corporate ESG report compilation.
Verified emission reduction data helps enterprises cope with EU CBAM carbon tariffs and carbon quota management, lowering carbon compliance pressure for export enterprises to Europe and America, and improving product competitiveness.
Stable carbon reduction performance helps enterprises raise ESG ratings, meet requirements of international capital markets and sustainable development policies, strengthen green brand image and attract high-quality cooperation opportunities.
Stable and reliable valve operation reduces shutdown and maintenance frequency, cutting energy consumption and carbon emissions during maintenance. Long service life brings sustained carbon reduction benefits, helping enterprises achieve carbon neutrality goals and build sustainable production systems.
