Step 1: Order and Design
Based on the customer’s operating conditions (pressure, temperature, and medium), confirm the specifications and materials (e.g., PVC, CPVC, PP) of the electric butterfly valve, as well as the actuator parameters, and complete the structural design and drawing output.
Step 2: Raw Material Preparation & Molding
Select high-quality plastic raw materials and perform drying treatment. Mold key components such as the valve body and disc using injection molding or compression molding processes to ensure dimensional stability and corrosion resistance of the electric butterfly valve.
Step 3: Machining
Perform precision machining (such as turning and milling) on the valve body sealing surfaces, shaft bores, and other critical areas to ensure the sealing performance and assembly accuracy of the electric butterfly valve.
Step 4: Assembly
Assemble the valve body, valve disc, valve stem, and seals, and install the electric actuator to complete the overall assembly and commissioning of the electric butterfly valve.
Step 5: Testing & Quality Assurance
Conduct seal testing, strength testing, and electric actuator functional testing on the electric butterfly valve to ensure the product complies with international standards (such as ISO and DIN).
Step 6: Finishing, Packaging and Shipment
Clean and protect the product, apply labels, and package it to ensure the electric butterfly valve remains undamaged during transport, then arrange for shipment.
