Equipment and spare partsBrowse manufacturers Search by manufacturerDirect supply of industrial control valves, process instrumentation, and plant automation systems manufactured by Chongqing Chuanyi Automation Co., Ltd. We engineer and deliver heavy-duty modulating control valves, PDS smart pressure transmitters, electromagnetic/vortex flowmeters, temperature assemblies, level gauges, CEMS stations, and DCS control platforms.
We supply the complete lineup of industrial control, modulating, and emergency shutdown valves manufactured by Chongqing Chuanyi Automation Co., Ltd. The product family encompasses top-guided single-seated globe valves (ZJHM/ZJHP), double-seated heavy-duty valves (ZJHN), balanced cage-guided control valves (ZJHQ/ZJHR) engineered for severe pressure drop cavitation suppression, and precision micro-flow valves (ZJHV). For abrasive slurries, high-viscosity media, and chemical lines, we deliver V-notch control.
PDS series smart pressure and differential pressure transmitters from Chongqing Chuanyi Automation Co., Ltd. represent a benchmark of accuracy and field endurance across refining, petrochemicals, power utilities, and metallurgy. The PDS instrument family incorporates PDS403/PDS405 gauge pressure transmitters, PDS423 absolute pressure transmitters, PDS443 micro-draft and PDS463 high-differential pressure models, PDS473/PDS483 direct-flange level transmitters, and flagship PDS803/PDS873 ultra-precision transmitters. Utilizing monocrystalline silicon resonant.
Chongqing Chuanyi flow metering portfolio encompasses all primary physics principles for precision liquid, gas, and steam measurement. For conductive fluids, chemical reagents, and abrasive mineral slurries, we provide EMF/MF electromagnetic flowmeters with diverse lining and electrode selections. For saturated and superheated steam, compressed air, and process gases, LUGB/VFM vortex flowmeters incorporate onboard multivariable temperature and pressure sensors for automatic steam density compensation.
Chongqing Chuanyi temperature measurement division manufactures a comprehensive portfolio of contact temperature sensors, primary thermowells, and head-mounted transmitters for thermal power plants, nuclear facilities, chemical reactors, and metallurgical furnaces. The thermocouple offering encompasses WRN (Type K), WRE (Type E), WRP (Type S), WRR (Type B), and WRK (Type N) models capable of operating in continuous severe thermal environments up to +1800 °C..
For dependable continuous and point level monitoring of liquids, pastes, corrosive slurries, and bulk solids in pressurized reactors, storage tanks, and dust-laden silos, Chongqing Chuanyi manufactures an advanced portfolio of level instruments. The flagship MPS7000 80 GHz FMCW non-contact radar series features an ultra-narrow 3° beam angle, high penetration through steam and dust, and millimeter measurement precision. Complementing the lineup are MPS5000.
Chongqing Chuanyi analytical division specializes in turnkey Continuous Emission Monitoring Systems (CEMS) and industrial process gas analyzers for coal-fired power utilities, metallurgical smelting complexes, flue gas desulfurization (FGD) skids, and cement kilns. The flagship PS7400 CEMS platform performs continuous automated monitoring of flue gas pollutant concentrations (SO2, NOx, CO, CO2, O2), particulate dust opacity, velocity, flow, pressure, temperature, and moisture. Turnkey packages.
For turnkey automation of petrochemical units, chemical synthesis plants, municipal water treatment works, and power generation boilers, Chongqing Chuanyi delivers high-availability Distributed Control Systems (DCS). The enterprise-class PAS300 DCS platform is architected around complete decentralization and comprehensive 1:1 hardware redundancy. PAS300 incorporates dual-redundant high-speed controller CPUs, redundant industrial fiber-optic Ethernet network backbones, and a modular library of intelligent I/O modules (AI/AO with.
Chongqing Chuanyi intelligent asset health and functional precision materials division manufactures advanced hardware and analytical software platforms for predictive monitoring of critical rotating machinery (steam/gas turbines, centrifugal pumps, heavy compressors, and industrial gearboxes). Online vibration and stress-wave diagnostic systems detect micro-cracks, bearing fatigue, shaft misalignment, and gear mesh anomalies at their inception. To deliver precision electrical drive regulation, we supply SC600 high-performance.
Our application engineers analyze process conditions (fluid chemistry, differential pressure, line velocity, temperature ranges), performing precise Kv/Cv valve sizing and selecting wetted metallurgy (PTFE, PFA, Hastelloy, Titanium) and bus protocols (HART, Profibus-PA, Modbus) for seamless DCS integration.
CQCY valves and instruments are widely deployed across refinery hydrocracking units, catalytic reforming skids, power plant FGD desulfurization systems, metallurgical smelting converters, and long-distance transmission pipelines.
Chongqing Chuanyi manufacturing processes are certified to ISO 9001, ISO 14001, and ISO 45001 standards. Products comply with SIL 2/SIL 3 functional safety, ATEX/IECEx explosion-proof directives, and ANSI/FCI 70-2 Class IV/V/VI seat leakage tolerances.
All CQCY instrumentation and valve packages are dispatched directly from Chongqing production facilities in heavy-duty export packaging accompanied by factory inspection reports, calibration certificates, and material test reports. We offer an official 12-month warranty and genuine replacement spares.
