Procetek, the registered trademark of Shanghai Transitec Mechatronic Co., Ltd., is a technology-driven system integrator specializing in high-performance valves, and oil-free compression solutions.
As your Flow Technology Partner, we go beyond supplying components. We work alongside our customers to improve system reliability, operational safety, and lifecycle performance in demanding industrial environments.
What “Flow Technology Partner” Means
Being a Flow Technology Partner means more than delivering products. It means supporting your system across its entire lifecycle:
From component selection to system integrati
From installation to long-term operation
From troubleshooting to performance optimization
Our goal is simple: Ensure your fluid systems run safely, efficiently, and reliably over time.
From Components to Integrated Systems
As your Flow Technology Partner, Procetek combines:
High-performance industrial butterfly valves
Oil-free screw compressors and blowers
Roots blowers for continuous duty
This system-level approach helps reduce complexity, improve compatibility, and lower total cost of ownership (TCO).
Innovation at the Core: Penta-offset Valve Technology
As a Flow Technology Partner, we continuously innovate to solve real operational challenges.
Moving beyond traditional triple-offset designs, Procetek has pioneered the Penta-offset "Ball-Butterfly" Valve—a disruptive technology that combines the robust sealing of a ball valve with the compact, lightweight advantages of a butterfly valve.
Zero-Friction Kinematics
Our unique penta-offset geometry ensures the disc completely disengages from the seat upon opening, achieving frictionless movement throughout the 90° stroke.
Self-Cleaning Spherical Seal
Utilizing an asymmetrical spherical sealing system, the valve naturally wipes away debris, ensuring stable sealing performance and an ultra-long service life.
Extreme Capability
Engineered for millions of cycles under pressure, our valves excel in ultra-low temperatures (-196°C), high temperatures (1200°C), and high-pressure ratings (up to 2500LB).
Strategic Focus: Flow Under Extreme Conditions
Our expertise is defined not by a single industry, but by the ability to handle extreme operating conditions, including:
-
High-frequency switching systems
-
High-pressure and high-temperature environments
-
Cryogenic media handling (LNG, LOX, LIN)
-
Oil-free processes requiring high purity
This enables us to serve a wide range of industries:
-
Industrial gas and air separation (ASU)
-
LNG and cryogenic systems
-
Petrochemical and refining
-
Power and energy systems
-
Environmental and air treatment
-
Advanced manufacturing and industrial processing
Legacy System Upgrade & OEM Replacement
Industrial systems evolve, but many operations rely on legacy equipment.
Procetek supports customers with high-compatibility replacement solutions:
-
Form-Fit-Function engineering approach
-
Seamless integration into existing systems
-
Lifecycle extension up to 30%
-
Reduced downtime and retrofit risk
Engineering DNA: Built on Reliability
Our engineering philosophy is rooted in rail transit systems, where safety and reliability are critical.
As a Flow Technology Partner, we apply the same discipline across all industrial applications:
-
IRIS / ISO-based engineering standards
-
Rigorous testing and validation
-
Zero-failure design mindset
