Material Selection and Preparation: High-grade materials such as Stainless Steel (304, 316, 316L), Carbon Steel (WCB), and various alloys are chosen based on the intended application's pressure, temperature, and corrosive environment. For instance, 316L Stainless Steel is often preferred for highly corrosive media due to its enhanced resistance. Raw materials undergo strict incoming inspection, including chemical composition analysis and mechanical property testing, to ensure compliance with ASTM or EN standards.
-
Body & End Connection Fabrication (Casting/Forging):
-
Casting: For larger valves or complex geometries, molten metal is poured into molds. This process is followed by heat treatment (e.g., annealing, normalizing) to relieve internal stresses and optimize mechanical properties.
-
Forging: For higher pressure ratings and superior material integrity, metal billets are plastically deformed under high pressure and temperature. Forging enhances grain structure, eliminating porosity and improving strength and fatigue resistance, crucial for the body and end connections of a 2 pcs ball valve.
-
CNC Machining: Precision machining is critical for achieving tight tolerances. Computer Numerical Control (CNC) machines are used to shape the valve body, end caps, ball, and stem. This includes precise boring of the spherical cavity for the ball, machining the stem for smooth rotation, and threading or flanging end connections to ANSI B16.5 or DIN standards. The QSL3S-1 model, for example, features a precision-machined ball and seat interface for reliable sealing.
-
Ball and Seat Grinding/Polishing: The spherical ball and the valve seats are ground and polished to achieve an exceptionally smooth surface finish. This ensures minimal friction during operation and a bubble-tight shut-off. Lapping techniques are often employed to create a perfect mating surface between the ball and seats.
-
Assembly: Components are meticulously assembled in a clean environment. This includes inserting the blow-out proof stem, placing the seats (e.g., PTFE, RPTFE, PEEK for various temperatures), installing the ball, and bolting the two body pieces together. The assembly sequence is critical to ensure proper alignment and sealing integrity. The mounting pad (e.g., ISO 5211 standard for QSL3S-1) is integrated during this stage or as part of the body casting/forging.
-
Testing and Quality Assurance: Every 2pcs ball valve undergoes rigorous testing to comply with international standards.
-
Hydrostatic Shell Test: Pressure testing of the valve body to verify its structural integrity against design pressure (e.g., API 598, MSS SP-61).
-
Seat Leakage Test: Testing the sealing capability of the valve seats against leakage (e.g., API 598, ISO 5208).
-
Fugitive Emissions Testing: For critical applications, valves may undergo fugitive emission tests to ISO 15848-1 or API 622, ensuring minimal leakage to the atmosphere.
-
Functional Test: Verifying smooth operation, quarter-turn actuation, and torque requirements.
-
Surface Treatment and Packaging: Final surface treatments, such as painting, passivation, or protective coatings, are applied. Valves are then carefully packaged to prevent damage during transit, often with protective end caps and robust crating.
This comprehensive process ensures that each 2pcs ball valve delivered to clients offers exceptional service life, energy efficiency through reduced pressure drop in full-bore designs, and superior corrosion resistance due to material selection and surface finish.
