Step 1: Order and Design
Based on customer requirements, determine the dimensions, pressure rating, connection standards (e.g., DIN/ANSI), and materials (e.g., PVC/CPVC/PP) for the turbo butterfly valve. Complete the structural design and confirm the drawings, including the design of the valve body, disc, and turbo actuator.
Step 2: Raw Material Preparation & Molding
Select high-quality plastic raw materials, dry them, and then process the valve body, disc, and certain structural components of the turbo butterfly valve via injection molding or compression molding to ensure material uniformity and dimensional stability.
Step 3: Machining
Machine the molded turbo butterfly valve components to precision, including turning of sealing surfaces, drilling of holes, and flange surface finishing, to ensure fitting accuracy and sealing performance.
Step 4: Assembly
Assemble the valve body, disc, seal rings, and gear operator to complete the turbo butterfly valve assembly, while adjusting the transmission mechanism to ensure smooth opening and closing without sticking.
Step 5: Testing & Quality Assurance
The assembled turbo butterfly valve undergoes seal testing, pressure testing, and operating torque testing to ensure compliance with relevant standards (such as ISO/API) and customer requirements.
Step 6: Finishing, Packaging and Shipment
The product is cleaned and protected, clearly labeled, and packaged (in cardboard or wooden crates). Shipment is arranged to ensure the turbo butterfly valve remains undamaged during transit.
Turbo butterfly valve is an industrial valve controlled by a worm gear drive mechanism. It is widely used in industrial piping systems—such as those in the metallurgy, power generation, petrochemical, water supply and drainage, and fire protection industries—where the medium temperature is high, serving to shut off, connect, and regulate flow.
These valves are widely used in:
Oil and Gas
Chemical Processing
Power Plants
Water Treatment
Metallurgy and Mining
Agriculture and Irrigation
