Welded Y-type forged steel stop valves are high-performance stop valves suitable for high pressure and high-temperature conditions in various industrial fields.

Definition and Application

Welded Y-Type Forged Steel Stop Valves are a type of stop valve connected by welding, primarily used in industries such as oil, chemicals, fertilizer, and power, for cutting off or connecting media like water, oil, steam, and acidic mediums.

Design and structural features

Design features of the焊接Y型锻钢截止阀 include:

The valve body and cover are welded together to ensure both sealing and strength.

‌The sealing surface is made of Stellite hard alloy, which features wear resistance, corrosion resistance, and friction resistance, thereby extending the service life.‌

The valve rod has been heat treated and surface nitrided, enhancing its corrosion and wear resistance.

Utilizing a bellows seal design, it eliminates the drawback of quick aging and leakage in the stuffing box of ordinary valve stems, improves energy efficiency, and enhances the safety of production equipment.

Application Scenarios and Advantages

Welded Y-type forged steel stop valves are suitable for the following scenarios:

High-pressure and high-temperature conditions, such as deep-sea platforms and Sinopec pipelines.

Low-flow resistance design, reducing pressure drop of the medium in the pipeline.

‌Extended seal life, tested for 100,000 cycles of opening and closing, ensuring long-term stable operation.‌

‌Intelligent operation experience, the low-torque design enhances operational efficiency.‌

Manufacturing Standards and Materials

The manufacturing standards for the Y-type forged steel stop valve include:

API 623-2013, JIS E101, and NB/T 47044-2014 specifications.

‌Material variety includes A105 forgings, A182 F22, A182 F304(L), and A182 F316(L), etc.‌
