Recently, the Quality Inspection Center of the Safety Inspection Branch under PetroChina Ningxia Petrochemical Company completed the procurement of a large-scale intelligent safety valve test bench for performance testing of 8”–24” safety valves. Following an open, fair, and transparent tender process, Zhejiang Youji Machinery Technology Co., Ltd. once again won the bid for PetroChina’s safety inspection projects with its JLA-Z high-precision intelligent safety valve testing machine.
The awarded product is a national patented technology (Patent No.: ZL 2013 2 0894666.7) with independent intellectual property rights. The supplied model, JLA-Z-600, delivers precision up to 0.25% with a resolution of 0.01 MPa. Both the control cabinet and all liquid-contact components are made from 304 stainless steel, using stainless steel piping and high-pressure switch valves to ensure durability and corrosion resistance.
Key Features & Applications
- Specifically designed for large-diameter safety valves in petrochemical and metallurgical refining industries.
- Tests safety valve performance parameters including set pressure, opening (pop-off) pressure, and strength.
- Combines simplified structure, full functionality, high accuracy, and user-friendly operation.
As the latest generation of large-diameter intelligent safety valve testing equipment independently developed by Zhejiang Youji, the JLA-Z-600 has already been adopted by:
- Daqing Oilfield Construction Engineering Company
- CNOOC Daya Bay Valve Testing Center
Renowned for its high precision, intelligent control, energy efficiency, and ease of operation, the JLA-Z-600 remains the preferred choice for petrochemical and metallurgical enterprises seeking industry-leading safety valve testing solutions.
