ABOUT
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 for demanding industrial environments.
Who We Are
At Procetek, we believe industrial performance is not defined by individual components alone, but by how an entire system performs over time. We work alongside customers to improve system reliability, operational safety, and lifecycle performance in complex and extreme conditions.
Technology-Driven Integration
We combine advanced valve engineering, oil-free screw compression, and Roots blower technologies into practical system-level solutions that reduce complexity and improve compatibility.
Engineering for Reliability
Our engineering philosophy is built on rigorous standards, validated performance, and a zero-failure mindset shaped by demanding rail transit and industrial applications.
From Selection to Integration
We help customers choose the right components and combine them into systems that work reliably under real operating conditions.
From Installation to Operation
Our role continues beyond delivery, supporting installation, commissioning, and long-term system stability.
From Troubleshooting to Optimization
We assist in identifying issues, improving performance, and extending service life throughout the system lifecycle.
From Components to Integrated Systems
Procetek combines key product technologies into a system-level approach that helps lower total cost of ownership while improving operational efficiency.
High-Performance Industrial Butterfly Valves
Designed for severe service conditions requiring dependable sealing, long service life, and stable performance.
Oil-Free Screw Compressors & Blowers
Built for processes where air purity, efficiency, and low contamination risk are critical to production quality.
Roots Blowers for Continuous Duty
Reliable solutions for applications demanding robust performance in long-running and continuous industrial operations.
Innovation at the Core
Moving beyond traditional triple-offset designs, Procetek has developed the Penta-offset “Ball-Butterfly” Valve — a breakthrough technology that combines the sealing strength of a ball valve with the compact advantages of a butterfly valve.
Zero-Friction Kinematics
The penta-offset geometry ensures the disc fully disengages from the seat upon opening, enabling frictionless movement throughout the 90° stroke.
Self-Cleaning Spherical Seal
An asymmetrical spherical sealing system naturally wipes away debris, maintaining stable sealing performance and extending service life.
Extreme Capability
Engineered for millions of cycles under pressure, with performance in ultra-low temperatures down to -196°C, high temperatures up to 1200°C, and pressure ratings up to 2500LB.
Strategic Focus: Flow Under Extreme Conditions
Our expertise is not defined by a single industry, but by our ability to solve fluid system challenges under severe operating conditions.
