Step 1: Order and Design
Based on the operating conditions provided by the customer—such as nominal diameter, pressure rating, temperature, medium type, and jacket heating/insulation requirements—determine the structural configuration, main dimensions, seat sealing method, and jacket connection scheme for the jacketed globe valve, and complete the drawing design and process review.
Step 2: Forging & Casting
In accordance with the material requirements for the jacketed globe valve, key components such as the valve body, bonnet, and disc are forged or cast. The valve body must meet the structural strength requirements for both the main flow path and the jacket cavity. After casting, the components undergo desanding, heat treatment, and raw material inspection.
Step 3: Machining
Precision machining is performed on the valve body, bonnet, stem, disc, and flange sealing surfaces. The machining focus for the jacketed globe valve lies in the dimensional accuracy and concentricity of the main flow path, seat sealing surfaces, and jacket flow channel interfaces to ensure proper subsequent assembly and media circulation.
Step 4: Assembly
Assemble the machined parts in accordance with process requirements, including the valve seat, disc, stem, packing, bonnet, and handwheel. During the assembly of the jacketed globe valve, the fit of the jacket connection ports, gaskets, and connecting bolts must also be inspected to ensure a reliable seal between the valve body and the jacket section.
Step 5: Testing & Quality Assurance
After assembly, the jacketed globe valve undergoes shell strength testing, seal testing, operational testing, and jacket cavity leakage testing. Concurrently, the appearance, dimensions, material reports, and pressure test records are verified to ensure the product complies with relevant standards and customer requirements.
Step 6: Painting and Finishing
After passing inspection, the valve’s exterior surfaces are cleaned, treated with rust prevention, and spray-painted. Non-machined surfaces are painted as required, flange surfaces are properly protected, and nameplates, markings, packaging, and final pre-shipment inspections are completed.
It is primarily used in high-temperature, high-pressure environments or applications requiring medium insulation in industries such as chemicals, petroleum, and metallurgy.
