Precise Control and Zero-Leakage for Closed Pipeline Systems
German office Erlangen, Germany | Local Production in China
Our Technological Advantages
Measurable, tested and documented — from stainless steel valves to flow sensors.
Wide Pressure & Temperature Range
Work pressure 0.2-10 bar with 16 bar maximum, media temperature -40 °C to +115 °C (max. 120 °C) — one valve platform from the data center to the wind turbine.
100 % Helium Leak Test | Zero Leakage
Every valve is 100 % helium leak-tested before delivery. SUS 316L bodies withstand circulating cooling media and keep CDU and rack-level loops permanently leak-free.
Precision Measurement | Smart Connectivity
Electromagnetic flowmeters with ±0.5 % accuracy and a 1:150 turndown ratio, plus PPA vortex sensors with no moving parts; outputs via IO-Link, RS-485 Modbus and 4-20 mA.
German Engineering | China Production
Developed with German engineering in Erlangen and produced locally in China — ISO 9001:2015 certified, delivered in under 30 days from our Greater China operations center.
