Quality Control in Producing ANSI Globe and Butterfly Valves

At Zhejiang Xiongxiang Valve Co., Ltd., manufacturing is not just about casting metal and assembling parts—it is about crafting components that meet stringent quality standards and stringent performance metrics. In our valve factory, the production of both the ANSI Globe Valve and the ANSI Butterfly Valve undergoes rigorous quality control, because these valves often operate under demanding conditions.

When producing an ANSI Globe Valve, the precision of the seating surface and the alignment of the stem and plug are critical. Our machining team ensures that tolerances are tight and surfaces are smooth, to guarantee consistent sealing and flow behavior. The globe valve’s internal flow path must be manufactured accurately to ensure that the pressure drop and flow control behave as engineered. We also conduct leak testing, endurance testing, and cycle testing to verify that each globe valve meets performance standards.

On the other hand, for the ANSI Butterfly Valve, the disc and the stem connection must be very precise to ensure smooth quarter-turn operation and dependable sealing. The seat material (e.g., resilient rubber or metallic liner) is chosen carefully, and the valve body is often stress tested under pressure to confirm that the flanged ends (ANSI standard flanges) maintain integrity. We also test for torque, leakage, and durability. The short face-to-face design of butterfly valves demands tight control in assembly to avoid misalignment.

Moreover, because both valve types are built to ANSI-compatible dimensions, our quality assurance team verifies flange dimensions, bolt hole patterns, and pressure class markings to match ANSI B16.5 or other relevant standards. This ensures that when our customers integrate these valves into broader systems, installation is straightforward and reliable.

Through careful design, rigorous inspection, and continuous improvement, Zhejiang Xiongxiang Valve Co., Ltd. builds ANSI Globe Valves and ANSI Butterfly Valves that serve in industrial environments with trust and stability. Our commitment to quality helps minimize field failures and ensures long-term performance.
