Step 1: Order and Design
Confirm the technical specifications of the ASME globe valve based on the pressure rating, dimensions, material, and connection standards provided by the customer.
The engineering department completes drawing design, structural verification, and manufacturing process reviews in accordance with ASME, API, and relevant standards to ensure the valve meets the requirements of the operating conditions.
Step 2: Forging & Casting
Select appropriate raw materials according to order specifications, and perform forging or precision casting on major components such as the valve body, bonnet, and disc.
Pressure-bearing components of the ASME globe valve undergo heat treatment and blank inspection after forming to ensure dense internal structure and stable mechanical properties.
Step 3: Machining
Precision machining is performed on the valve body flange surfaces, sealing surfaces, stem threads, and seat mating surfaces.
This stage is a critical step in the manufacturing of ASME globe valves, directly affecting sealing performance, operational flexibility, and dimensional accuracy.
Step 4: Assembly
Machined and inspected parts are cleaned, matched, and assembled, including components such as the valve stem, disc, bonnet, packing, and handwheel.
During assembly, coaxiality, sealing surface contact, and operating torque must be strictly controlled to ensure the ASME globe valve operates smoothly and reliably.
Step 5: Testing & Quality Assurance
After assembly, the ASME globe valve undergoes shell strength testing, sealing tests, and necessary air tightness tests. Appearance, dimensions, and markings are inspected according to standards.
The quality department simultaneously verifies material reports, heat treatment records, and inspection documents to ensure the product meets factory release requirements.
Step 6: Painting and Finishing
After passing the pressure test, the valve surface is cleaned, treated with rust prevention, painted, and the nameplate is affixed.
Finally, packaging, protective measures, and warehousing are completed to ensure the product remains in good condition during transportation and delivery.
Primarily used in high-temperature, high-pressure piping systems in thermal power plants, petrochemical plants, and other industries, these valves control the flow of non-corrosive media such as water and steam.
