Across China’s energy arteries that span from east to west and north to south, there is an “invisible corps” silently safeguarding national energy security — the valve actuators from Yangzhou Hengchun Electronics Co., Ltd. From long-distance natural gas pipelines to crude oil and refined product pipelines, from transmission hubs in bustling cities to unmanned valve chambers in desert wastelands, Hengchun actuators, with over 20 years of stable operation track record, have witnessed and participated in the vigorous development of China’s oil and gas pipeline industry.
Since entering the long-distance pipeline sector in the early 2000s, Hengchun Electronics has focused on the R&D and manufacturing of valve actuators. To date, more than 30,000 Hengchun actuators are operating stably on the long-distance pipelines of Sinopec, PetroChina, and PipeChina, with the longest service history exceeding 20 years.
This is not merely a stack of numbers — it is a record of reliable operation day after day, year after year. Whether in the extreme cold of -40°C in northern Xinjiang, the high-temperature and high-humidity southern coast, the sandstorm-ravaged northwest Gobi, or the rainy southwest mountainous regions, Hengchun actuators always stand their ground, ensuring the safe and smooth operation of every pipeline.
The long-distance pipeline system is a complex and sophisticated entity, where every valve node is critical to the operational safety of the entire pipeline. With outstanding performance and reliability, Hengchun actuators have achieved full-scenario, full-position deep coverage in long-distance pipelines:
Trunk Line Block Valve Chambers: As the first line of pipeline safety defense, trunk line ball valves driven by Hengchun actuators can quickly cut off gas supply in emergencies to prevent accident escalation
Station Inlet/Outlet Valves: Key nodes connecting stations with trunk lines, ensuring safe and reliable station maintenance and isolation
Station Inlet/Outlet Control Valves: Precisely control station inlet/outlet pressure and flow rate to ensure stable pipeline operating parameters
Filter Separator Inlet/Outlet Valves: Protect core filtration equipment and enable maintenance without pipeline shutdown
Compressor Inlet/Outlet Valves: Ensure safe start-stop and isolation maintenance of compressor units
Air Compressor Inlet/Outlet Valves: Reliable control for station utility systems
Pig Launcher/Receiver Valves: Specialized valves for pig launcher and receiver cylinders, supporting pipeline pigging operations
Distribution Stations/Distribution Valves: Enable natural gas distribution to downstream users
Pressure Regulation Skids/Metering Skids: Precise control in skid-mounted integrated devices
ESD Emergency Shut-off Valves: Core execution units of emergency shutdown systems with fast response and high reliability
Vent Valves/Blowdown Valves: Reliable execution for station safety relief and blowdown systems
Safety Valves/Pressure Relief Valves: The last line of defense for overpressure protection
Instrument Root Valves: Isolation and protection for precision instruments
Bypass Valves: Pressure balance control for trunk valve bypass lines
Valve Chamber Block Valves: Core equipment for line block valve chambers, supporting remote control and automatic shut-off
Station Inlet/Outlet Valves: Connection hubs between pumping stations and trunk lines
Main Pump Inlet/Outlet Valves: Safe isolation and control for oil pump units
Charge Pump Inlet/Outlet Valves: Reliable control for main pump booster systems
Filter Inlet/Outlet Valves: Isolation valves for oil filtration and purification systems
Flow/Pressure Control Valves: Precisely regulate oil flow and pressure to meet process requirements
Pressure Relief Valves/Safety Valves: Pipeline overpressure protection
Pig Launcher/Receiver Valves: Specialized valves for crude oil pipeline pigging operations
Blowdown Valves: Station blowdown system control
Tank Farm Inlet/Outlet Valves: Oil product inlet/outlet control for storage tank farms
Metering System Valves: Precise control for custody transfer metering systems
Heating Furnace Inlet/Outlet Valves: Safety control for crude oil heating systems
Pressure Reduction Station Valves: Pressure control for refined product pipeline pressure reduction stations
Batch Transfer Switching Valves: Key switching equipment for sequential batch transport of refined products
Various Skid-Mounted Units: Metering skids, pressure regulation skids, filter separation skids, chemical injection skids, and other integrated devices
Full valve type compatibility: Ball valves, gate valves, plug valves, control valves, check valves, butterfly valves, and more
Multiple drive type adaptation: Electric, pneumatic, electro-hydraulic, gas-hydraulic, and more
In the long-distance pipeline sector, actuators for large-bore, high-pressure valves have always been an industry technical challenge. With profound technical accumulation, Hengchun Electronics has successfully achieved localized application of valve actuators up to 56 inches, Class 900, breaking the technical monopoly of foreign brands.
Whether it’s high-torque driving of fully welded ball valves or precise control of high-pressure gate valves, Hengchun actuators deliver stable and reliable power output, ensuring accurate valve opening and closing under all operating conditions.
Sinopec, PetroChina, and PipeChina — the three leading enterprises in China’s energy industry — have nearly stringent access standards and quality requirements for equipment suppliers. With excellent product quality and comprehensive service system, Hengchun Electronics has successfully entered the supplier lists of all three central SOEs and become their long-term partner.
From the West-East Gas Pipeline to the China-Russia Eastern Route, from the western crude oil pipeline to the eastern refined product pipeline network, from PipeChina’s “One National Network” to local pipeline network construction, Hengchun actuators can be found across China’s energy arteries.
20 years of relentless effort, 30,000+ units stably operating, and the choice of three central SOEs. Hengchun Electronics will continue to uphold the philosophy of “quality-oriented, innovation-driven,” providing more reliable and intelligent valve actuator solutions for the global oil and gas pipeline industry, and jointly safeguarding world energy security with our partners.
